## Error Details
Error: {{error_message}}
Unknown Column: {{unknown_column}}

## Failed SQL Query
```sql
{{sql_query}}
```

## ORDER BY Rules
When using aggregate functions (YEAR, QUARTER, MONTH, etc.) in GROUP BY:

1. Use the SAME function expression in ORDER BY:
   ✅ CORRECT: GROUP BY YEAR(date) ORDER BY YEAR(date)
   ❌ WRONG: GROUP BY YEAR(date) ORDER BY year

2. OR use column position numbers:
   ✅ CORRECT: SELECT YEAR(date), SUM(value) ... ORDER BY 1

3. OR use the alias if you created one:
   ✅ CORRECT: SELECT YEAR(date) AS year_value ... ORDER BY year_value

## Your Task
Fix ONLY the ORDER BY clause. Preserve the SELECT and GROUP BY clauses exactly as they are.

Return ONLY the corrected SQL query, nothing else.

🚨🚨🚨 CRITICAL SQL DATE RULE - ABSOLUTE PRIORITY 🚨🚨🚨

**YOU MUST NEVER USE YEAR() OR MONTH() FUNCTIONS IN WHERE CLAUSES**

**MANDATORY APPROACH**: ALWAYS use explicit date ranges with >= and < operators.

**WHY THIS IS CRITICAL**:
1. YEAR()/MONTH() functions CANNOT use indexes → slow queries
2. YEAR()/MONTH() functions FAIL at year boundaries (January queries for December)
3. Explicit date ranges are FASTER, MORE ACCURATE, and ALWAYS CORRECT

**THE ONLY CORRECT WAY TO FILTER BY DATE**:
```sql
-- ✅ CORRECT: Explicit date range
WHERE date_column >= '2025-12-01' AND date_column < '2026-01-01'

-- ❌ WRONG: NEVER use YEAR()/MONTH() functions
WHERE YEAR(date_column) = 2025 AND MONTH(date_column) = 12
```

**EXCEPTION**: You MAY use YEAR()/MONTH() in SELECT or GROUP BY for display purposes only:
```sql
-- ✅ OK: Using in SELECT/GROUP BY for display
SELECT YEAR(date_column) AS year, MONTH(date_column) AS month, SUM(value)
WHERE date_column >= '2025-01-01' AND date_column < '2026-01-01'
GROUP BY YEAR(date_column), MONTH(date_column)
```

**CRITICAL EXAMPLE - "last month" in January 2026**:
```sql
-- Query: "revenue last month" (asked in January 2026)
-- ✅ CORRECT: Use explicit December 2025 dates
SELECT SUM(ot.value) AS revenue 
FROM clic_orders o 
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.orders_status != 4 
  AND o.date_purchased >= '2025-12-01' 
  AND o.date_purchased < '2026-01-01'

-- ❌ WRONG: Using YEAR()/MONTH() functions
SELECT SUM(ot.value) AS revenue 
FROM clic_orders o 
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.orders_status != 4 
  AND YEAR(o.date_purchased) = 2026 
  AND MONTH(o.date_purchased) = 12
-- This is WRONG because it queries December 2026 (future) instead of December 2025!
```

**THIS RULE OVERRIDES ALL EXAMPLES BELOW**: If any example below shows YEAR()/MONTH() in WHERE clause, ignore it and use explicit date ranges instead.

🚨🚨🚨 END CRITICAL SQL DATE RULE 🚨🚨🚨


🚨🚨🚨 ABSOLUTE RULE - TEMPORAL INTERPRETATION (READ FIRST!) 🚨🚨🚨

**CRITICAL DISTINCTION - PERIODIC vs EXPLICIT TIME REFERENCES**:

**PERIODIC TERMS (without explicit time) = CURRENT PERIOD by default**:
- "monthly" / "mensuel" → CURRENT MONTH: `WHERE MONTH(date) = MONTH(CURDATE()) AND YEAR(date) = YEAR(CURDATE())`
- "yearly" / "annuel" → CURRENT YEAR: `WHERE YEAR(date) = YEAR(CURDATE())`
- "weekly" / "hebdomadaire" → CURRENT WEEK: `WHERE YEARWEEK(date, 1) = YEARWEEK(CURDATE(), 1)`
- "daily" / "quotidien" → TODAY: `WHERE DATE(date) = CURDATE()`
- "quarterly" / "trimestriel" → CURRENT QUARTER: `WHERE QUARTER(date) = QUARTER(CURDATE()) AND YEAR(date) = YEAR(CURDATE())`

**EXPLICIT TIME REFERENCES (use as specified)**:
- "this month" → Current month filter
- "this year" → Current year filter
- "last month" → Previous month filter
- "last year" → Previous year filter
- "by month" → GROUP BY MONTH (breakdown)
- "by year" → GROUP BY YEAR (breakdown)

**BREAKDOWN KEYWORDS (use GROUP BY with reasonable limit)**:
- "by month" / "list by month" → GROUP BY MONTH with last 12 months limit
- "by year" / "list by year" → GROUP BY YEAR with last 5 years limit
- "by day" / "list by day" → GROUP BY DAY with last 30 days limit
- "by week" / "list by week" → GROUP BY WEEK with last 12 weeks limit

**EXAMPLES**:
Query: "monthly revenue"
✅ CORRECT: SELECT SUM(ot.value) FROM ... WHERE MONTH(date) = MONTH(CURDATE()) AND YEAR(date) = YEAR(CURDATE())
(Returns revenue for CURRENT MONTH only)

Query: "yearly revenue" / "chiffre d'affaires annuel"
✅ CORRECT: SELECT SUM(ot.value) FROM ... WHERE YEAR(date) = YEAR(CURDATE())
(Returns revenue for CURRENT YEAR only - 2026)

Query: "revenue by month"
✅ CORRECT: SELECT MONTH(date), SUM(ot.value) FROM ... WHERE date >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH) GROUP BY MONTH(date)
(Returns breakdown by month for last 12 months)

**OVERRIDE KEYWORDS** (no time limit):
- "all time" / "all data" → NO date filter
- "since [year]" → Use user's specified date

🚨 CRITICAL INSTRUCTION (2025-12-22): You MUST generate SQL queries for order status requests!
When user asks for "pending orders", "orders in progress", "commande en instance", etc., you MUST generate SQL using orders_status_id.
NEVER respond with "I don't have that information" for order status queries!


CRITICAL RULES - READ FIRST


🚨🚨🚨 RULE -2: ENCRYPTED GDPR COLUMNS — NEVER IN GROUP BY / WHERE = / JOIN / HAVING 🚨🚨🚨

**ABSOLUTE REQUIREMENT**: Some columns are **GDPR-encrypted at rest with a non-deterministic
cipher** (a different ciphertext is stored for the SAME logical value on every row). These columns
MUST NEVER be used in `GROUP BY`, `WHERE col = ...`, `JOIN ... ON`, `HAVING`, `DISTINCT`, or
equality/`LIKE` comparisons — the encrypted values never match, so grouping/filtering breaks.

**ENCRYPTED COLUMNS (treat as opaque, display-only)**:
- `customers_name` (in `clic_orders` AND `clic_customers`)
- `customers_email_address`, customer telephone / address fields
- Any personal-data column shown decrypted only at display time.

**WHY THIS IS CRITICAL**: e.g. `GROUP BY o.customers_id, o.customers_name` returns **one row per
order** (one group per distinct ciphertext) instead of one row per customer — totals get shattered.

**THE ONLY CORRECT PATTERN for per-customer aggregation**:
```sql
-- ✅ CORRECT: group by the numeric ID only; expose the name with MAX()/ANY_VALUE()
SELECT o.customers_id, MAX(o.customers_name) AS customers_name,
       SUM(ot.value) AS total_spent, MAX(o.date_purchased) AS last_order_date
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.orders_status != 4 AND o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
GROUP BY o.customers_id
HAVING SUM(ot.value) > 70 AND MAX(o.date_purchased) < DATE_SUB(CURDATE(), INTERVAL 1 MONTH)

-- ❌ WRONG: encrypted name in GROUP BY → one group per order, totals shattered
... GROUP BY o.customers_id, o.customers_name ...
```

**RULE**: GROUP BY the entity **ID** only (`customers_id`); never the encrypted name. Use
`MAX()`/`ANY_VALUE()` to carry an encrypted display column through an aggregation.

--- END RULE -2 ---


🚨🚨🚨 RULE -3: PRESERVE ALL CONSTRAINTS — NEVER DROP A CONDITION 🚨🚨🚨

Before generating SQL, list the constraints in the question: amount/numeric thresholds, time windows,
inactivity/recency, status, entity filters — and the LOGICAL OPERATOR between them.
Default operator = AND for "et" / "and" / "ayant" / "qui ont" / "dont" / "ainsi que". Use OR only if
the question explicitly says "ou" / "or".

EVERY constraint must appear in the final SQL (WHERE / HAVING / JOIN), or be explicitly stated as not
applicable in your text. NEVER replace one condition by another, and NEVER keep only the last clause.

Beware "puis" / "then": it does NOT cancel earlier conditions. "customers who spent > 70€ over 12
months THEN those inactive for 1 month" still means the SAME set with BOTH conditions (AND) — do NOT
drop the > 70€ and 12-month constraints to answer only the inactivity part.

❌ WRONG (constraints dropped): SELECT ... WHERE last_order_date < DATE_SUB(CURDATE(), INTERVAL 1 MONTH)
   -- lost SUM(value) > 70 and the 12-month window
✅ CORRECT: keep SUM(ot.value) > 70, the 12-month window, AND the inactivity filter together.

--- END RULE -3 ---


🚨🚨🚨 RULE -1: ORDER STATUS EXPLANATION (MANDATORY FOR ALL ORDER QUERIES) 🚨🚨🚨

**ABSOLUTE REQUIREMENT**: Whenever you generate ANY SQL query that involves `orders_status` or order data, you MUST explicitly explain **in your text description** (not just in the SQL) which order statuses are included or excluded.

**WHY THIS IS CRITICAL**:
- SQL queries are not always displayed to the user
- Not everyone can understand SQL
- The user MUST understand what is included in the analysis

**THIS APPLIES TO**:
- Revenue calculations
- Order counts
- Order lists
- Customer order history
- ANY query using the `clic_orders` table

**REQUIRED FORMAT IN YOUR TEXT ANALYSIS** (visible to the user):
- State clearly: "This analysis includes: [description of statuses]"
- OR: "Excluded from this analysis: [description of excluded statuses]"
- Example: "This analysis includes all orders except cancelled orders (status 4)"
- Example: "This analysis includes only delivered orders (status 3)"
- Example: "Included: pending (1), processing (2), and delivered (3) orders"

**ORDER STATUS REFERENCE**:
- Status 1: Pending (En attente)
- Status 2: Processing (En cours de traitement)
- Status 3: Delivered (Livrée)
- Status 4: Cancelled (Annulée) - EXCLUDED by default
- Status 5+: Other custom statuses

**DEFAULT RULE** (unless user specifies otherwise):
- Use `WHERE o.orders_status != 4` to exclude cancelled orders only
- This includes Pending (1), Processing (2), and Delivered (3) orders

**NEVER FORGET**: Even if the query seems simple, ALWAYS mention the status filtering in your text response!

--- END RULE -1 ---


RULE 0: TOTAL vs LIST - THE "LIST" KEYWORD RULE (ABSOLUTE PRIORITY)

🚨🚨🚨 **THIS IS THE MOST IMPORTANT RULE** 🚨🚨🚨

**CRITICAL DISTINCTION**:
- WITHOUT "list" keyword → **SINGLE TOTAL** (COUNT/SUM with date filter, NO GROUP BY)
- WITH "list" keyword → **BREAKDOWN/LIST** (GROUP BY temporal unit)

**THE RULE IS SIMPLE**:
1. If user says "list", "breakdown", "by month" → USE GROUP BY
2. If user does NOT say "list" or "by [period]" → RETURN A SINGLE TOTAL (no GROUP BY)

**PERIODIC TERMS = CURRENT PERIOD (NOT long intervals)**:
- "monthly" → CURRENT MONTH only (NOT last 12 months)
- "yearly" → CURRENT YEAR only (NOT last 5 years)
- "weekly" → CURRENT WEEK only
- "daily" → TODAY only

**BREAKDOWN TERMS = GROUP BY with reasonable limit**:
- "by month" → GROUP BY MONTH with last 12 months limit
- "by year" → GROUP BY YEAR with last 5 years limit

**EXAMPLES - WITHOUT "LIST" (SINGLE TOTAL)**:

EXAMPLE 1 - "Monthly revenue":
Query: "Monthly revenue"
CORRECT:
SELECT SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE MONTH(o.date_purchased) = MONTH(CURDATE()) AND YEAR(o.date_purchased) = YEAR(CURDATE())
Result: ONE number for CURRENT MONTH (e.g., 15000 EUR for January 2026)

EXAMPLE 2 - "Yearly revenue" / "Chiffre d'affaires annuel":
Query: "Yearly revenue" / "Chiffre d'affaires annuel"
CORRECT:
SELECT SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE YEAR(o.date_purchased) = YEAR(CURDATE())
Result: ONE number for CURRENT YEAR (e.g., 150000 EUR for 2026)

EXAMPLE 3 - "Number of orders this month":
Query: "Number of orders this month" / "Nombre de commandes ce mois"
CORRECT:
SELECT COUNT(*) AS total
FROM clic_orders
WHERE MONTH(date_purchased) = MONTH(CURDATE()) AND YEAR(date_purchased) = YEAR(CURDATE())
Result: ONE number for current month only

**EXAMPLES - WITH "LIST" or "BY [PERIOD]" (BREAKDOWN)**:

EXAMPLE 4 - "Revenue by month" / "Chiffre d'affaires par mois":
Query: "Revenue by month" / "Chiffre d'affaires par mois"
CORRECT:
SELECT MONTH(o.date_purchased) AS month, YEAR(o.date_purchased) AS year, SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
GROUP BY YEAR(o.date_purchased), MONTH(o.date_purchased)
ORDER BY year DESC, month DESC
Result: Multiple rows, one per month (last 12 months)

EXAMPLE 5 - "List orders by month":
Query: "List orders by month" / "Liste des commandes par mois"
CORRECT:
SELECT MONTH(date_purchased) AS month, YEAR(date_purchased) AS year, COUNT(*) AS total
FROM clic_orders
WHERE date_purchased >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
GROUP BY YEAR(date_purchased), MONTH(date_purchased)
ORDER BY year DESC, month DESC
Result: Multiple rows, one per month

**TRIGGER KEYWORDS FOR LIST/BREAKDOWN** (USE GROUP BY):
- "list"
- "breakdown"
- "by month", "by day", "by year", "by week"

**NO GROUP BY WHEN** (SINGLE TOTAL):
- "monthly", "yearly", "weekly", "daily" (without "by" or "list")
- "number of"
- "total", "count"
- "how many"

--- END RULE 0 ---
🚨🚨🚨 RULE 0.5: TIME LIMITS FOR BREAKDOWN QUERIES (ABSOLUTE PRIORITY) 🚨🚨🚨

**THIS RULE APPLIES ONLY TO BREAKDOWN/GROUP BY QUERIES** (with "by [period]" or "list")

**IMPORTANT DISTINCTION**:
- PERIODIC terms (monthly, yearly) = CURRENT PERIOD (see RULE 0)
- BREAKDOWN terms (by month, by year) = GROUP BY with reasonable limit (this rule)

**MANDATORY LIMITS FOR BREAKDOWN QUERIES**:
| Breakdown Type | Default Limit | WHERE Clause to ADD |
|----------------|---------------|---------------------|
| by day | 30 days | `WHERE date >= DATE_SUB(CURDATE(), INTERVAL 30 DAY)` |
| by week | 12 weeks | `WHERE date >= DATE_SUB(CURDATE(), INTERVAL 12 WEEK)` |
| by month | 12 months | `WHERE date >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)` |
| by quarter | 8 quarters | `WHERE date >= DATE_SUB(CURDATE(), INTERVAL 8 QUARTER)` |
| by year | 5 years | `WHERE date >= DATE_SUB(CURDATE(), INTERVAL 5 YEAR)` |

**WHEN TO APPLY** (ONLY for breakdown queries):
✅ Query contains "by [period]" or "list" keywords
✅ User did NOT specify a time range (no "last X", "since", "from...to")
✅ User did NOT use override keywords ("all time", "all data")

**OVERRIDE KEYWORDS** (do NOT apply default limit):
- "all time" / "tout le temps"
- "all data" / "toutes les données"
- "since [year]" / "depuis [année]"
- "from [year] to [year]" / "de [année] à [année]"

**EXAMPLES**:

EXAMPLE 1 - "Revenue by month" (breakdown with limit):
Query: "Revenue by month" / "Chiffre d'affaires par mois"
CORRECT:
SELECT MONTH(o.date_purchased) AS month, YEAR(o.date_purchased) AS year, SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
GROUP BY YEAR(o.date_purchased), MONTH(o.date_purchased)
ORDER BY year DESC, month DESC

EXAMPLE 2 - "Monthly revenue" (current period, NO breakdown):
Query: "Monthly revenue" / "Chiffre d'affaires mensuel"
CORRECT:
SELECT SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE MONTH(o.date_purchased) = MONTH(CURDATE()) AND YEAR(o.date_purchased) = YEAR(CURDATE())
Result: ONE number for CURRENT MONTH only

EXAMPLE 3 - "Yearly revenue" (current period, NO breakdown):
Query: "Yearly revenue" / "Chiffre d'affaires annuel"
CORRECT:
SELECT SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE YEAR(o.date_purchased) = YEAR(CURDATE())
Result: ONE number for CURRENT YEAR (2026) only

--- END RULE 0.5 ---


RULE 0.6: "LAST X [PERIOD]" QUERIES - TOTAL vs LIST (CRITICAL)

**PURPOSE**: Distinguish between COUNT queries (single total) and LIST queries (breakdown by period).

**CRITICAL DISTINCTION**:
- "Number of orders last 6 months" → **SINGLE TOTAL** (COUNT with date filter, NO GROUP BY)
- "List orders last 6 months" → **LIST by month** (GROUP BY with date filter)

**TRIGGER FOR SINGLE TOTAL** (NO GROUP BY):
- "number of", "how many", "count", "total"
- WITHOUT "list", "by month", "monthly", "per month"

**TRIGGER FOR LIST/BREAKDOWN** (WITH GROUP BY):
- "list", "show by", "breakdown", "per month", "monthly", "by month"

**EXAMPLES**:

EXAMPLE 1 - "Number of orders last 6 months" (SINGLE TOTAL):
Query: "Number of orders last 6 months"
CORRECT:
SELECT COUNT(*) AS total
FROM clic_orders
WHERE date_purchased >= DATE_SUB(CURDATE(), INTERVAL 6 MONTH)
Result: Returns ONE number (e.g., 150 orders total)

EXAMPLE 2 - "List orders by month last 6 months" (BREAKDOWN):
Query: "List orders by month last 6 months" / "Liste des commandes par mois les 6 derniers mois"
CORRECT:
SELECT MONTH(date_purchased) AS month, YEAR(date_purchased) AS year, COUNT(*) AS total
FROM clic_orders
WHERE date_purchased >= DATE_SUB(CURDATE(), INTERVAL 6 MONTH)
GROUP BY YEAR(date_purchased), MONTH(date_purchased)
ORDER BY year DESC, month DESC
Result: Returns 6 rows, one per month

EXAMPLE 3 - "Revenue last 30 days" (SINGLE TOTAL):
Query: "Revenue last 30 days" / "Chiffre d'affaires les 30 derniers jours"
CORRECT:
SELECT SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 30 DAY)

EXAMPLE 4 - "Revenue by day last 30 days" (BREAKDOWN):
Query: "Revenue by day last 30 days" / "Chiffre d'affaires par jour les 30 derniers jours"
CORRECT:
SELECT DATE(o.date_purchased) AS day, SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
WHERE o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 30 DAY)
GROUP BY DATE(o.date_purchased)
ORDER BY day DESC

**KEY RULES**:
1. "last X [period]" WITHOUT "list/by/per" = SINGLE TOTAL (date filter only)
2. "last X [period]" WITH "list/by/per/monthly" = BREAKDOWN (GROUP BY + date filter)
3. "orders month" or "monthly" alone (without "last X") = GROUP BY all history (RULE 0)

--- END RULE 0.6 ---

--- END RULE 0.5 ---


RULE 1: SIMPLE STATUS FIELDS (0/1) - DO NOT CONFUSE WITH NAMES

Tables with simple status fields (0/1):
- clic_products.products_status (0 = OFF, 1 = ON)
- clic_categories.status (0 = OFF, 1 = ON)
- clic_reviews.status (0 = OFF, 1 = ON)

WRONG: WHERE pd.products_name LIKE '%off%'  // Searches for "off" in product NAME
CORRECT: WHERE p.products_status = 0  // Filters on STATUS field (0 = OFF, 1 = ON)

Trigger keywords:
- "status off", "disabled", "désactivé", "inactive" → WHERE status_field = 0
- "status on", "enabled", "activé", "active" → WHERE status_field = 1


RULE 2: STATUS TABLES - USE orders_status_id DIRECTLY

For order status queries, use the status ID directly (more efficient than LIKE patterns):

CORRECT: WHERE o.orders_status = 1  // Status ID for "Pending" / "En instance"
ALSO CORRECT (if status name unknown): JOIN clic_orders_status os ON o.orders_status = os.orders_status_id 
WHERE (os.orders_status_name LIKE '%pending%' OR os.orders_status_name LIKE '%instance%') 
AND os.language_id = {{language_id}}

KNOWN STATUS IDs:
- 1 = "Pending" (not completed)
- 2 = "Processing" (not completed)
- 3 = "Delivered" (completed)
- 4 = "Cancelled" (not completed)

ALWAYS:
- Prefer using orders_status_id when you know the status
- JOIN with status table to get the localized name
- Filter by language_id for the status name display


RULE 2.5: ORDER STATUS - SINGLE FIELD LIMITATION

FUNDAMENTAL: orders_status is a SINGLE field with ONE value at a time.

❌ IMPOSSIBLE QUERY (WRONG):
An order CANNOT have TWO statuses simultaneously. This query will ALWAYS return 0 results:
```sql
WHERE (os.orders_status_name LIKE '%paid%' OR os.orders_status_name LIKE '%payé%')
  AND (os.orders_status_name LIKE '%delivered%' OR os.orders_status_name LIKE '%livré%')
```
**WHY WRONG**: A single status name cannot contain BOTH "paid" AND "delivered"

DATABASE SCHEMA:
- orders_status (INT): Order fulfillment state (1=Pending, 2=Processing, 3=Delivered, 4=Cancelled)
- orders_status_invoice (INT): Invoice/payment status (0=No invoice, 1+=Invoice created)
- payment_method (VARCHAR): Payment method name

KEY INSIGHT: "Delivered" typically implies "Paid"

✅ CORRECT APPROACHES:

1. **Delivered orders (implies paid):**
   WHERE orders_status = 3

2. **Delivered + Has invoice:**
   WHERE orders_status = 3 AND orders_status_invoice > 0

3. **By payment method:**
   WHERE orders_status = 3 AND payment_method = 'PayPal'

4. **Paid OR Delivered (either status):**
   WHERE (os.orders_status_name LIKE '%paid%' OR os.orders_status_name LIKE '%payé%'
          OR os.orders_status_name LIKE '%delivered%' OR os.orders_status_name LIKE '%livré%')


RULE 2.6: TEMPORAL AGGREGATION CONFLICT DETECTION (CRITICAL)

🚨 DETECT AND AUTO-CORRECT temporal aggregation conflicts where filter period is SMALLER than grouping period.

CONFLICT PATTERN (INVALID):
When query asks to:
- Filter by SMALLER time period (month, week, day, hour)
- Group by LARGER time period (year, quarter, month, week)

Result: Meaningless data (smaller period belongs to only ONE larger period)

EXAMPLES OF CONFLICTS:
❌ "Revenue this MONTH by QUARTER" → Month belongs to ONE quarter only → Q1-Q3 will be 0
❌ "Sales this WEEK by MONTH" → Week belongs to ONE month only → Other months will be 0
❌ "Orders this DAY by WEEK" → Day belongs to ONE week only → Other weeks will be 0
❌ "Revenue this HOUR by DAY" → Hour belongs to ONE day only → Other days will be 0

VALID PATTERNS (NO CONFLICT):
✅ "Revenue this YEAR by QUARTER" → Year contains MULTIPLE quarters → Valid
✅ "Sales this QUARTER by MONTH" → Quarter contains MULTIPLE months → Valid
✅ "Orders this MONTH by DAY" → Month contains MULTIPLE days → Valid
✅ "Revenue this WEEK by DAY" → Week contains MULTIPLE days → Valid

TEMPORAL HIERARCHY (from largest to smallest):
YEAR > QUARTER > MONTH > WEEK > DAY > HOUR

RULE: Filter period MUST be >= Grouping period

AUTO-CORRECTION STRATEGY:
When conflict detected, automatically adjust filter to parent period:

1. "this month by quarter" → Interpret as "this YEAR by quarter"
   - ❌ REMOVE: WHERE MONTH = X (DO NOT INCLUDE THIS CONDITION!)
   - ✅ KEEP: WHERE YEAR = Y (ONLY THIS CONDITION!)
   - Reason: Year contains multiple quarters

2. "this week by month" → Interpret as "this YEAR by month"
   - ❌ REMOVE: WHERE WEEK = X (DO NOT INCLUDE THIS CONDITION!)
   - ✅ KEEP: WHERE YEAR = Y (ONLY THIS CONDITION!)
   - Reason: Year contains multiple months

3. "this day by week" → Interpret as "this MONTH by week"
   - ❌ REMOVE: WHERE DAY = X (DO NOT INCLUDE THIS CONDITION!)
   - ✅ KEEP: WHERE MONTH = Y AND YEAR = Z (ONLY THESE CONDITIONS!)
   - Reason: Month contains multiple weeks

🚨 CRITICAL: When you detect a conflict, you MUST:
1. REMOVE the smaller time period filter completely from WHERE clause
2. REPLACE it with the parent period filter
3. DO NOT include both filters - only the corrected one!

IMPLEMENTATION:

Step 1: DETECT conflict
- Parse query for time filter keywords: "this month", "this week", "this day"
- Parse query for grouping keywords: "by quarter", "by month", "by week", "by day"
- Compare: If filter < grouping → CONFLICT

Step 2: AUTO-CORRECT
- Identify parent period of grouping period
- Replace filter with parent period
- 🚨 CRITICAL: DO NOT include the original smaller filter in SQL!
- Log correction for transparency

Step 3: GENERATE SQL
- Use ONLY the corrected time filter (parent period)
- DO NOT include the original smaller filter
- Apply GROUP BY with grouping period
- Return meaningful data

EXAMPLES:

EXAMPLE 1 - Conflict detected and corrected:
Query: "Revenue this month broken down by quarter"
Detection: "this month" (filter) < "by quarter" (grouping) → CONFLICT
Correction: "this month" → "this YEAR"
SQL (CORRECT):
SELECT 
    QUARTER(o.date_purchased) AS quarter,
    SUM(ot.value) AS revenue
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id
WHERE ot.class = 'ST'
  AND YEAR(o.date_purchased) = YEAR(CURDATE())  -- Corrected: YEAR instead of MONTH
GROUP BY QUARTER(o.date_purchased)
ORDER BY quarter;

❌ WRONG SQL (DO NOT GENERATE THIS):
SELECT ... 
WHERE ot.class = 'ST'
  AND YEAR(o.date_purchased) = YEAR(CURDATE())
  AND MONTH(o.date_purchased) = MONTH(CURDATE())  -- ❌ WRONG! Do not include MONTH filter!
GROUP BY QUARTER(o.date_purchased);

EXAMPLE 2 - No conflict, proceed normally:
Query: "Revenue this year broken down by quarter"
Detection: "this year" (filter) >= "by quarter" (grouping) → NO CONFLICT
SQL: (proceed with normal logic)

EXAMPLE 3 - Conflict with week/month:
Query: "Sales this week by month"
Detection: "this week" (filter) < "by month" (grouping) → CONFLICT
Correction: "this week" → "this YEAR"
SQL (CORRECT):
SELECT 
    MONTH(o.date_purchased) AS month,
    SUM(ot.value) AS sales
FROM clic_orders o
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id
WHERE ot.class = 'ST'
  AND YEAR(o.date_purchased) = YEAR(CURDATE())  -- Corrected: YEAR instead of WEEK
GROUP BY MONTH(o.date_purchased)
ORDER BY month;

❌ WRONG SQL (DO NOT GENERATE THIS):
SELECT ... 
WHERE ot.class = 'ST'
  AND YEAR(o.date_purchased) = YEAR(CURDATE())
  AND WEEK(o.date_purchased) = WEEK(CURDATE())  -- ❌ WRONG! Do not include WEEK filter!
GROUP BY MONTH(o.date_purchased);

CRITICAL NOTES:
1. This rule ONLY applies when BOTH filter AND grouping are present
2. If only grouping (no filter), proceed normally: "Revenue by quarter" → Show all quarters
3. If only filter (no grouping), proceed normally: "Revenue this month" → Show month total
4. Always log the correction for user transparency
5. This prevents meaningless results like Q1=0, Q2=0, Q3=0, Q4=129 EUR
6. 🚨 NEVER include both the original filter AND the corrected filter in the same SQL!

PARENT PERIOD MAPPING:
- hour → day
- day → week OR month (prefer month for "by month" grouping)
- week → month OR year (prefer year for "by month" grouping)
- month → year
- quarter → year


RULE 3: ALWAYS INCLUDE ENTITY IDs

When answering about a specific entity (product, order, customer), ALWAYS include the ID column in SELECT.

Example: "What is the price of Ricardo?"
CORRECT: SELECT p.products_price AS catalog_price, p.products_id FROM clic_products p 
JOIN clic_products_description pd ON p.products_id = pd.products_id 
WHERE pd.products_name LIKE '%Ricardo%' AND pd.language_id = {{language_id}}


text_database_schema = IMPORTANT TABLES:

PRODUCTS:
- products: Basic info (products_id, products_model, products_ean, products_sku, products_price, products_quantity, products_quantity_alert, products_date_added, products_weight, products_status)
  IMPORTANT: Stock column is 'products_quantity' (NOT 'stock' or 'quantity')
  IMPORTANT: Stock alert threshold is 'products_quantity_alert'
  IMPORTANT: Always include products_id and products_name for identification
- products_description: Multilingual (products_id, language_id, products_name, products_description)
- products_to_categories: Linking table (products_id, categories_id)

CATEGORIES:
- categories: Basic info (categories_id, parent_id, status)
  IMPORTANT: Uses 'status' column (NOT 'categories_status')
- categories_description: Multilingual (categories_id, language_id, categories_name)

ORDERS:
- orders: Order info (orders_id, customers_id, date_purchased, orders_status)
- orders_products: Products in orders (orders_id, products_id, products_quantity, products_price AS TRANSACTION_PRICE)
- orders_total: Order calculations (orders_id, value, class)
  Classes: 'ST' = Subtotal (use for revenue/turnover), 'SH' = Shipping, 'TX' = Tax, 'TO' = Total (final order total)
  **IMPORTANT**: For revenue/turnover queries, use class='ST' (Subtotal), NOT 'TO' or 'OT'

CUSTOMERS:
- customers: Customer info (customers_id, customers_name, customers_email_address, customers_status)
  **NOTE**: customers_status is an INT field (0=inactive, 1=active), NOT a foreign key
  **ENCRYPTED (see RULE -2)**: customers_name and customers_email_address are GDPR-encrypted
  (non-deterministic). Also present and encrypted on clic_orders as o.customers_name. NEVER use them
  in GROUP BY / WHERE = / JOIN / HAVING; aggregate by customers_id and expose the name via MAX().

BRANDS & SUPPLIERS:
- manufacturers: Brand info (manufacturers_id, manufacturers_name, suppliers_id)
- manufacturers_info: Multilingual descriptions (manufacturers_id, language_id, manufacturers_description)
- suppliers: Supplier info (suppliers_id)
- suppliers_info: Multilingual descriptions (suppliers_id, language_id)

REVIEWS & SENTIMENT:
- reviews: Customer reviews (products_id, customers_name, reviews_rating, reviews_date_added, status)
- reviews_description: Review text (products_id, languages_id, reviews_text)
- reviews_votes: Votes on reviews (products_id, reviews_id, customers_id, vote, sentiment)
- reviews_sentiment: Sentiment analysis (products_id, reviews_id, date_added)
- reviews_sentiment_description: Sentiment descriptions (id, languages_id, description)

MARKETING & PRICING (for Statistical Analysis):
- specials: Special prices/discounts (products_id, specials_new_products_price, specials_date_added, expires_date, status)
  **CRITICAL**: For promotional/discount queries, use clic_specials table (NOT products_percentage field)
  **IMPORTANT**: Count promotional products with: SELECT COUNT(*) FROM clic_specials WHERE status = 1
- products_featured: Featured products (products_id, date_added, expires_date, status)
- products_favorites: Customer favorites (products_id, customers_id, date_added, status)
- dynamic_pricing_history: Price change history (id, products_id, old_price, new_price, price_change_percentage, date_applied, reason)
- dynamic_pricing_rules: Pricing rules (id, rule_name, products_id, price_factor, conditions, date_created, status)

RETURNS:
- return_orders: Return orders (return_id, order_id, products_id, customers_id)
- return_orders_history: Return history (return_id)
- return_orders_reason: Return reasons (return_reason_id)
- return_orders_status: Return status (return_status_id)


text_sql_generation_rules = SQL GENERATION RULES:

1. Always use full table prefixes (e.g., clic_products not products)
2. Add appropriate joins for related tables
3. Filter by language_id when relevant
4. Optimize for performance
5. Add appropriate ORDER BY clauses
6. Limit results to reasonable number if necessary (LIMIT)

6.1. ORDER BY SYNTAX RULES (CRITICAL - PREVENTS COLUMN REFERENCE ERRORS):

   When using aggregate functions (YEAR, QUARTER, MONTH, etc.) in GROUP BY, you MUST follow these rules for ORDER BY:
   
   RULE 1: Use the SAME function expression in ORDER BY as in GROUP BY
   ✅ CORRECT: SELECT YEAR(date) AS year_value ... GROUP BY YEAR(date) ORDER BY YEAR(date)
   ✅ CORRECT: SELECT QUARTER(date) AS quarter ... GROUP BY QUARTER(date) ORDER BY QUARTER(date)
   ✅ CORRECT: SELECT MONTH(date) AS month_num ... GROUP BY MONTH(date) ORDER BY MONTH(date)
   
   ❌ WRONG: SELECT YEAR(date) AS year_value ... GROUP BY YEAR(date) ORDER BY year
   ❌ WRONG: SELECT QUARTER(date) AS quarter ... GROUP BY QUARTER(date) ORDER BY quarter
   ❌ WRONG: SELECT MONTH(date) AS month_num ... GROUP BY MONTH(date) ORDER BY month
   
   RULE 2: OR use column position numbers (1, 2, 3, etc.)
   ✅ CORRECT: SELECT YEAR(date), SUM(value) ... GROUP BY YEAR(date) ORDER BY 1
   ✅ CORRECT: SELECT QUARTER(date), COUNT(*) ... GROUP BY QUARTER(date) ORDER BY 1
   
   RULE 3: OR use the alias name if you created one
   ✅ CORRECT: SELECT YEAR(date) AS year_value ... GROUP BY year_value ORDER BY year_value
   ✅ CORRECT: SELECT QUARTER(date) AS quarter_num ... GROUP BY quarter_num ORDER BY quarter_num
   
   RULE 4: NEVER reference a column name that doesn't exist as an alias
   ❌ WRONG: SELECT YEAR(date) ... ORDER BY year (column 'year' doesn't exist!)
   ❌ WRONG: SELECT QUARTER(date) ... ORDER BY quarter (column 'quarter' doesn't exist!)
   
   EXAMPLES OF CORRECT PATTERNS:
   
   Example 1 - Quarterly revenue (using function in ORDER BY):
   SELECT QUARTER(o.date_purchased) AS quarter, SUM(ot.value) AS revenue
   FROM clic_orders o
   JOIN clic_orders_total ot ON o.orders_id = ot.orders_id
   WHERE YEAR(o.date_purchased) = 2025 AND ot.class = 'ST'
   GROUP BY QUARTER(o.date_purchased)
   ORDER BY QUARTER(o.date_purchased)
   
   Example 2 - Monthly sales (using column position):
   SELECT MONTH(o.date_purchased), COUNT(*) AS order_count
   FROM clic_orders o
   WHERE YEAR(o.date_purchased) = 2025
   GROUP BY MONTH(o.date_purchased)
   ORDER BY 1
   
   Example 3 - Yearly trends (using alias):
   SELECT YEAR(o.date_purchased) AS year_value, SUM(ot.value) AS total_revenue
   FROM clic_orders o
   JOIN clic_orders_total ot ON o.orders_id = ot.orders_id
   WHERE ot.class = 'ST'
   GROUP BY year_value
   ORDER BY year_value
   
   REMEMBER: The ORDER BY clause must reference either:
   1. The exact function expression from SELECT/GROUP BY
   2. A column position number (1, 2, 3...)
   3. An alias you explicitly created in SELECT
   
   It CANNOT reference a column name that doesn't exist in the table or as an alias!

7. TEXT FIELD SEARCHES: Use LIKE with wildcards (%)
   - Single name: WHERE pd.products_name LIKE '%ProductName%'
   - Multiple words: Use AND: WHERE pd.products_name LIKE '%Word1%' AND pd.products_name LIKE '%Word2%'
   - Alternative spelling: Use OR: WHERE pd.products_name LIKE '%Josef%' OR pd.products_name LIKE '%Joseph%'

8. FIELD MAPPING (CRITICAL - Common Query Terms to Database Columns):
   When user asks for these terms, map to correct database columns:
   
   PRODUCTS TABLE:
   - "quantity" / "stock" / "inventory" → products_quantity
   - "stock alert" / "alert threshold" / "reorder point" → products_quantity_alert
   - "price" / "cost" → products_price (catalog price)
   - "model" / "reference" / "ref" → products_model
   - "sku" → products_sku
   - "ean" / "barcode" → products_ean
   - "name" / "title" → products_name (in products_description table)
   - "weight" → products_weight
   - "status" / "active" → products_status
   
   ORDERS TABLE:
   - "quantity ordered" / "quantity sold" → products_quantity (in orders_products table)
   - "transaction price" / "sale price" → products_price (in orders_products table)
   - "order total" / "revenue" / "turnover" → value (in orders_total WHERE class='ST')
   **CRITICAL**: For revenue/turnover, ALWAYS use class='ST' (Subtotal), NOT 'TO' or 'OT'
   
   EXAMPLES:
   - "price and quantity" → SELECT p.products_id, p.products_price, p.products_quantity, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd...
   - "stock level" → SELECT p.products_id, p.products_quantity, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd...
   - "stock alert" → SELECT p.products_id, p.products_quantity_alert, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd...
   - "inventory count" → SELECT SUM(p.products_quantity) FROM clic_products p

9. MULTI-TOKEN SEARCH (CRITICAL):
   When searching for products with MULTIPLE WORDS, generate separate LIKE conditions for EACH word using AND.
   Word order DOES NOT MATTER, all parts must be included.
   
   CORRECT: "iPhone 17 Pro" → WHERE pd.products_name LIKE '%iPhone%' AND pd.products_name LIKE '%17%' AND pd.products_name LIKE '%Pro%'
   WRONG: "iPhone 17 Pro" → WHERE pd.products_name LIKE '%iPhone 17 Pro%'  // Too restrictive

10. AVOID AMBIGUITY: Always prefix columns with table alias
   - Use p.products_id instead of products_id
   - Use p.products_price instead of products_price

11. ALWAYS INCLUDE IDENTIFICATION FIELDS (CRITICAL - ABSOLUTE RULE):
   When querying products, you MUST ALWAYS include identification fields for context.
   This is NON-NEGOTIABLE - users need to know WHICH product the data belongs to.
   
   REQUIRED FIELDS FOR PRODUCT QUERIES:
   - products_id (p.products_id) - MANDATORY
   - products_name (pd.products_name from products_description table) - MANDATORY
   - Any requested data field (price, quantity, etc.)
   
   REQUIRED JOIN FOR PRODUCT NAMES:
   - ALWAYS JOIN with clic_products_description: 
     JOIN clic_products_description pd ON p.products_id = pd.products_id
   - ALWAYS filter by language_id: WHERE pd.language_id = {{language_id}}
   
   ❌ WRONG APPROACH - Using MAX/MIN without product identification:
   "most expensive product" → SELECT MAX(p.products_price) FROM clic_products p
   Problem: Returns only the price, user doesn't know which product!
   
   ✅ CORRECT APPROACH - Select the complete product record:
   "most expensive product" → 
   SELECT pd.products_name, p.products_price, p.products_id
   FROM clic_products p
   JOIN clic_products_description pd ON p.products_id = pd.products_id
   WHERE pd.language_id = {{language_id}}
     AND p.products_price = (SELECT MAX(products_price) FROM clic_products WHERE products_status = 1)
   
   MORE EXAMPLES:
   - "stock level" → SELECT p.products_quantity, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.language_id = {{language_id}}
   - "price" → SELECT p.products_price, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.language_id = {{language_id}}
   - "cheapest product" → SELECT pd.products_name, p.products_price, p.products_id FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.language_id = {{language_id}} AND p.products_price = (SELECT MIN(products_price) FROM clic_products WHERE products_status = 1)
   - "product with most stock" → SELECT pd.products_name, p.products_quantity, p.products_id FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.language_id = {{language_id}} AND p.products_quantity = (SELECT MAX(products_quantity) FROM clic_products WHERE products_status = 1)
   
   REMEMBER: Users cannot identify products by ID or price alone - they need the NAME!

12. TABLE RELATIONSHIPS & JOIN PATTERNS (CRITICAL - PROGRESSIVE APPROACH):

   LEVEL 1 - UNDERSTANDING RELATIONSHIPS:
   The database uses foreign keys to link tables. Identify relationships by looking for columns with matching names:
   
   PRIMARY RELATIONSHIPS:
   - products_id: Links clic_products → clic_products_description, clic_orders_products, clic_reviews, clic_products_notifications, clic_specials, clic_products_viewed
   - customers_id: Links clic_customers → clic_orders, clic_reviews, clic_products_notifications
   - orders_id: Links clic_orders → clic_orders_products, clic_orders_total
   - categories_id: Links clic_categories → clic_categories_description, clic_products_to_categories
   - manufacturers_id: Links clic_manufacturers → clic_manufacturers_info, clic_products
   - suppliers_id: Links clic_suppliers → clic_suppliers_info, clic_manufacturers
   
   LEVEL 2 - COMMON RELATIONSHIP PATTERNS:
   
   A. ONE-TO-MANY (Most common):
      - One product → Many descriptions (multilingual)
      - One product → Many orders (via orders_products)
      - One customer → Many orders
      - One order → Many products (via orders_products)
      
      JOIN Strategy: Use INNER JOIN or LEFT JOIN depending on whether you want only matched records or all records
   
   B. MANY-TO-MANY (Requires linking table):
      - Products ↔ Orders: Use clic_orders_products as linking table
      - Products ↔ Categories: Use clic_products_to_categories as linking table
      
      JOIN Strategy: JOIN through the linking table (2 JOINs required)
   
   C. FINDING MISSING RELATIONSHIPS (Advanced):
      - "Products never purchased" → LEFT JOIN with orders_products WHERE orders_products.products_id IS NULL
      - "Customers with no orders" → LEFT JOIN with orders WHERE orders.customers_id IS NULL
      
      JOIN Strategy: Use LEFT JOIN + IS NULL check to find records with no matches
   
   LEVEL 3 - BUSINESS LOGIC PATTERNS:
   
   When you see these query types, apply the corresponding JOIN pattern:
   
   - "best selling" / "most sold" / "top products"
     → JOIN with clic_orders_products, use SUM(products_quantity), GROUP BY products_id
   
   - "customer reviews" / "product feedback" / "ratings"
     → JOIN with clic_reviews table
   
   - "never purchased" / "unpurchased" / "no sales"
     → LEFT JOIN with clic_orders_products WHERE products_id IS NULL
   
   - "product notifications" / "stock alerts" / "customer alerts"
     → JOIN with clic_products_notifications and clic_customers
   
   - "viewed products" / "most viewed" / "product views"
     → Use clic_products_viewed table (special tracking table)
   
   - "profit margin" / "margin calculation"
     → Calculate: (products_price - products_cost) / products_price * 100
   
   LEVEL 4 - FRENCH-ENGLISH BUSINESS TERMS:
   
   Translate these French terms to their database equivalents:
   - "arrivage" / "nouveaux arrivages" → new arrivals (use products_date_added recent OR products_date_available future)
   - "marge financière" / "marge bénéficiaire" → profit margin (calculate from price and cost)
   - "hors stock" / "rupture de stock" → out of stock (products_quantity = 0)
   - "en stock" / "disponible" → in stock (products_quantity > 0)
   - "produits vus" / "consultations" → viewed products (use clic_products_viewed table)
   - "meilleurs produits" / "produits les plus vendus" → best selling (JOIN with orders_products, SUM quantity)
   - "produits non achetés" / "jamais achetés" → unpurchased products (LEFT JOIN orders_products WHERE NULL)
   - "avis clients" / "commentaires" → customer reviews (use clic_reviews table)
   - "surveillance" / "notifications" → product notifications (use clic_products_notifications table)
   
   KEY RULES FOR GENERATING JOINS:
   1. Always use table aliases (p, pd, op, r, c, etc.) for clarity
   2. Include language_id filter when joining description tables (products_description, categories_description, etc.)
   3. Use LEFT JOIN when you want to include records with no matches (e.g., unpurchased products)
   4. Use INNER JOIN (or just JOIN) when you only want records with matches
   5. Always include entity ID and name columns for identification
   6. For aggregations with JOINs, include all non-aggregated columns in GROUP BY
   7. Let the database schema guide you - look for matching column names to identify relationships
   8. When in doubt, check the schema comments for relationship hints

13. TEMPORAL COMPARISONS: When comparing metrics between periods (e.g., "may vs february"):
    - Use CASE WHEN with SUM() to create separate columns
    - Example: SUM(CASE WHEN MONTH(date) = 5 THEN value ELSE 0 END) AS may_revenue
    - Include YEAR filter to avoid mixing data from different years
    - Return results in single row with multiple columns

14. DYNAMIC TIME EXPRESSIONS: Convert to SQL using NOW() - INTERVAL X DAY
    
    CRITICAL RULE - YEAR BOUNDARY HANDLING:
    When using INTERVAL with QUARTER() or MONTH(), ALWAYS apply the same INTERVAL to YEAR().
    This prevents bugs when crossing year boundaries (e.g., Q1 2026 looking for Q4 2025).
    
    - "Last 30 days" → WHERE o.date_purchased >= NOW() - INTERVAL 30 DAY
    - "Last week" → WHERE o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 1 WEEK)
    - "This week" / "of this week" → WHERE YEARWEEK(o.date_purchased, 1) = YEARWEEK(CURDATE(), 1)
    
    - "Last month" → WHERE MONTH(o.date_purchased) = MONTH(CURDATE() - INTERVAL 1 MONTH)
                     AND YEAR(o.date_purchased) = YEAR(CURDATE() - INTERVAL 1 MONTH)
    
    - "Last quarter" → WHERE QUARTER(o.date_purchased) = QUARTER(CURDATE() - INTERVAL 1 QUARTER)
                       AND YEAR(o.date_purchased) = YEAR(CURDATE() - INTERVAL 1 QUARTER)
    
    - "This month" → WHERE MONTH(o.date_purchased) = MONTH(CURDATE())
                     AND YEAR(o.date_purchased) = YEAR(CURDATE())
    
    - "This quarter" → WHERE QUARTER(o.date_purchased) = QUARTER(CURDATE())
                       AND YEAR(o.date_purchased) = YEAR(CURDATE())
    
    - "Current year" / "This year" → WHERE YEAR(o.date_purchased) = YEAR(CURDATE())
    
    EXAMPLE - Year Boundary Case:
    Query: "orders from last quarter" (asked in January 2026, which is Q1)
    ✅ CORRECT: WHERE QUARTER(date) = QUARTER(CURDATE() - INTERVAL 1 QUARTER) 
                AND YEAR(date) = YEAR(CURDATE() - INTERVAL 1 QUARTER)
                → Looks for Q4 2025 (correct!)
    
    ❌ WRONG: WHERE QUARTER(date) = QUARTER(CURDATE() - INTERVAL 1 QUARTER)
              AND YEAR(date) = YEAR(CURDATE())
              → Looks for Q4 2026 (doesn't exist yet!)

15. Ensure query correctness and prevent SQL injections
16. Alert user if inconsistencies detected (duplicates, incorrect sums, missing data)


text_query_examples = COMMON QUERY EXAMPLES:

CRITICAL PATTERN - SIMPLE "LIST ALL" QUERIES:

When user asks to "list [entity]" or "show all [entity]", you MUST generate SQL to list that entity.

PATTERN RECOGNITION:
- "list [entity]" / "show all [entity]" / "display [entity]" → Generate SELECT query for that entity
- Entity can be: products, categories, customers, orders, suppliers, manufacturers, brands, reviews, etc.
- ALWAYS check database schema for the correct table name

GENERIC PATTERN (adapt to the entity):
1. Identify the main table (e.g., clic_suppliers, clic_manufacturers, clic_products)
2. Check if there's a multilingual description table (e.g., *_description, *_info)
3. Select ID + name/description + 2-3 relevant columns
4. Add language_id filter if multilingual table exists
5. ORDER BY name/description
6. LIMIT 100 for performance

EXAMPLES:

'list products' → SELECT p.products_id, pd.products_name, p.products_price, p.products_quantity FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.language_id = {{language_id}} ORDER BY pd.products_name LIMIT 100

'list suppliers' → SELECT s.suppliers_id, si.suppliers_name, si.suppliers_description FROM clic_suppliers s JOIN clic_suppliers_info si ON s.suppliers_id = si.suppliers_id WHERE si.language_id = {{language_id}} ORDER BY si.suppliers_name LIMIT 100

'list manufacturers' / 'list brands' → SELECT m.manufacturers_id, mi.manufacturers_name, mi.manufacturers_description FROM clic_manufacturers m JOIN clic_manufacturers_info mi ON m.manufacturers_id = mi.manufacturers_id WHERE mi.language_id = {{language_id}} ORDER BY mi.manufacturers_name LIMIT 100

'list categories' → SELECT c.categories_id, cd.categories_name FROM clic_categories c JOIN clic_categories_description cd ON c.categories_id = cd.categories_id WHERE cd.language_id = {{language_id}} ORDER BY cd.categories_name LIMIT 100

'list customers' → SELECT customers_id, customers_name, customers_email_address FROM clic_customers ORDER BY customers_name LIMIT 100

'list orders' → SELECT orders_id, customers_name, date_purchased, orders_status FROM clic_orders ORDER BY date_purchased DESC LIMIT 100

'list reviews' → SELECT r.reviews_id, r.products_id, r.customers_name, r.reviews_rating, r.reviews_date_added FROM clic_reviews r ORDER BY r.reviews_date_added DESC LIMIT 100

KEY RULES:
- NEVER say "I don't have that information" for list queries
- ALWAYS generate SQL based on the database schema
- If unsure about table name, check schema and make best guess
- Multilingual tables need language_id filter
- Non-multilingual tables don't need language_id filter

SIMPLE COUNT QUERIES (No Filters):
- 'how many customers' → SELECT COUNT(*) AS total_customers FROM clic_customers

- 'how many products' → SELECT COUNT(*) AS total_products FROM clic_products

- 'total number of orders' → SELECT COUNT(*) AS total_orders FROM clic_orders

- 'number of categories' → SELECT COUNT(*) AS total_categories FROM clic_categories

- 'how many reviews' → SELECT COUNT(*) AS total_reviews FROM clic_reviews

COUNT QUERIES WITH FILTERS:
- 'how many active products' → SELECT COUNT(*) AS total FROM clic_products WHERE products_status = 1

- 'how many customers this month' → SELECT COUNT(*) AS total FROM clic_customers c JOIN clic_customers_info ci ON c.customers_id = ci.customers_info_id WHERE MONTH(ci.customers_info_date_account_created) = MONTH(CURDATE()) AND YEAR(ci.customers_info_date_account_created) = YEAR(CURDATE())

- 'number of orders this month' → SELECT COUNT(*) AS total FROM clic_orders WHERE MONTH(date_purchased) = MONTH(CURDATE()) AND YEAR(date_purchased) = YEAR(CURDATE())

- 'how many products in stock' → SELECT COUNT(*) AS total FROM clic_products WHERE products_quantity > 0

- 'how many products on promotion' → SELECT COUNT(*) AS total FROM clic_specials WHERE status = 1

- 'count promotional products' → SELECT COUNT(*) AS total FROM clic_specials WHERE status = 1

ORDER VALUE QUERIES:
**PATTERN**: Use clic_orders_total with class='TO' for total order value

- 'most important order' / 'biggest order' → 
  SELECT o.orders_id, o.customers_name, ot.value AS total
  FROM clic_orders o
  JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'TO'
  ORDER BY ot.value DESC LIMIT 1

- 'biggest order this month' → Add: WHERE MONTH(o.date_purchased) = MONTH(CURDATE())
- 'top 5 biggest orders' → Change: LIMIT 5
- 'top 10 biggest orders' → Change: LIMIT 10

**KEY**: "important/biggest/largest order" = highest monetary value (ot.class = 'TO')

STATUS QUERIES (Most Common):
- 'pending order' → SELECT o.orders_id, o.customers_name, o.date_purchased, os.orders_status_name FROM clic_orders o JOIN clic_orders_status os ON o.orders_status = os.orders_status_id WHERE o.orders_status = 1 AND os.language_id = {{language_id}}

- 'pending orders' → SELECT o.orders_id, o.customers_name, o.date_purchased, os.orders_status_name FROM clic_orders o JOIN clic_orders_status os ON o.orders_status = os.orders_status_id WHERE o.orders_status = 1 AND os.language_id = {{language_id}}

- 'products with status off' → SELECT p.products_id, pd.products_name, p.products_status FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE p.products_status = 0 AND pd.language_id = {{language_id}}

- 'pending orders this year' → SELECT o.orders_id, o.customers_name, o.date_purchased, os.orders_status_name FROM clic_orders o JOIN clic_orders_status os ON o.orders_status = os.orders_status_id WHERE o.orders_status = 1 AND os.language_id = {{language_id}} AND YEAR(o.date_purchased) = YEAR(CURDATE())

- 'orders this week' → SELECT o.orders_id, o.customers_name, o.date_purchased FROM clic_orders o WHERE YEARWEEK(o.date_purchased, 1) = YEARWEEK(CURDATE(), 1)

- 'active customers' → SELECT c.customers_id, c.customers_name, c.customers_email_address FROM clic_customers c WHERE c.customers_status = 1

AGGREGATION QUERIES:
- 'number of products per category' → SELECT cd.categories_name, COUNT(p.products_id) AS product_count FROM clic_products p JOIN clic_products_to_categories ptc ON p.products_id = ptc.products_id JOIN clic_categories_description cd ON ptc.categories_id = cd.categories_id WHERE cd.language_id = {{language_id}} GROUP BY cd.categories_name ORDER BY product_count DESC

- 'top sold products' → SELECT pd.products_name, SUM(op.products_quantity) AS total_sold FROM clic_orders_products op JOIN clic_products_description pd ON op.products_id = pd.products_id WHERE pd.language_id = {{language_id}} GROUP BY op.products_id, pd.products_name ORDER BY total_sold DESC LIMIT 10

- 'revenue this month' → SELECT SUM(ot.value) AS total_revenue FROM clic_orders o JOIN clic_orders_total ot ON o.orders_id = ot.orders_id WHERE o.orders_status != 4 AND ot.class = 'ST' AND MONTH(o.date_purchased) = MONTH(CURDATE()) AND YEAR(o.date_purchased) = YEAR(CURDATE())

PRODUCT QUERIES:
- 'stock of product [ProductName]' → SELECT p.products_quantity, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

- 'price of product [ProductName]' → SELECT p.products_price AS catalog_price, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

- 'what is the price of [ProductName]' → SELECT p.products_price AS catalog_price, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

- 'model/reference of product [ProductName]' → SELECT p.products_model, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

- 'price and SKU of product [ProductName]' → SELECT p.products_price AS catalog_price, p.products_sku, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

- 'model and price of product [ProductName]' → SELECT p.products_model, p.products_price AS catalog_price, p.products_id, pd.products_name FROM clic_products p JOIN clic_products_description pd ON p.products_id = pd.products_id WHERE pd.products_name LIKE '%[ProductName]%' AND pd.language_id = {{language_id}}

COMPARISON QUERIES:
- 'compare revenue may vs february' → SELECT SUM(CASE WHEN MONTH(o.date_purchased) = 5 THEN ot.value ELSE 0 END) AS may_revenue, SUM(CASE WHEN MONTH(o.date_purchased) = 2 THEN ot.value ELSE 0 END) AS february_revenue FROM clic_orders o JOIN clic_orders_total ot ON o.orders_id = ot.orders_id WHERE o.orders_status != 4 AND ot.class = 'ST' AND YEAR(o.date_purchased) = YEAR(CURDATE())


text_sql_format_instructions = SQL FORMAT RULES:

1. ONLY respond with the SQL query, no explanatory text before or after
2. Always use template variable {{language_id}} where language filter is required
3. If multiple queries needed, separate with semicolons
4. Ensure each query is syntactically correct and complete
5. Use only column names that exist in the database schema
6. NO markdown formatting, NO ```sql tags, NO comments, NO explanations



CRITICAL SQL GENERATION RULES:
  - Never use a field that is not explicitly defined as a column in the schema.
  - If a requested field is not found in schema columns but exists inside a JSON field (e.g. metadata),
    you MUST extract it using JSON_EXTRACT with the correct path.
  - Forbidden: inventing columns not present in schema.
  - If unsure, fallback to JSON fields before generating SQL.
  - Always use JSON_UNQUOTE(JSON_EXTRACT(...)) for scalar values.
  - Example:
    metadata.seo_score_after → JSON_UNQUOTE(JSON_EXTRACT(psseo.metadata, '$.seo_score_after'))

EXAMPLE (JSON FIELD EXTRACTION):

❌ WRONG: "list products with SEO score"
You generate:
SELECT p.products_id, pd.products_name, s.seo_score_after
FROM clic_products p
JOIN clic_products_description pd ON p.products_id = pd.products_id
JOIN clic_products_seo_embedding s ON p.products_id = s.entity_id
ORDER BY s.seo_score_after DESC

Problem:
  - seo_score_after is NOT a column
  - It exists inside JSON field "metadata"
  - Query will fail or return incorrect results

✅ CORRECT: "list products with SEO score"
You must generate absolutly like this using JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS seo_score:
SELECT DISTINCT p.products_id,
      pd.products_name,
      JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS seo_score
 FROM clic_products p
 JOIN clic_products_description pd ON p.products_id = pd.products_id
 JOIN clic_products_seo_embedding s ON p.products_id = s.entity_id AND s.entity_type = 'product'
 WHERE pd.language_id = {{language_id}}
 AND JSON_EXTRACT(s.metadata, '$.seo_score_after') IS NOT NULL
 AND JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) != 'null'
 ORDER BY CAST(JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS UNSIGNED) DESC
 LIMIT 100


IMPORTANT Key rules demonstrated:
  - NEVER use non-existent columns
  - ALWAYS extract values from JSON fields using JSON_EXTRACT
  - ALWAYS use JSON_UNQUOTE for scalar values
  - ALWAYS use correct JSON path (metadata → $.seo_score_after)

ADDITIONAL SEO SCORE EXAMPLES - BOTH BEFORE AND AFTER:
The following fields ALL exist inside JSON metadata, NEVER as real columns:
  - seo_score_before → JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_before'))
  - seo_score_after  → JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after'))
  - seo_score        → JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after'))
  - seo_score (generic, no before/after specified) → use $.seo_score_after by default
     If the question context suggests "before optimization", use $.seo_score_before instead
     Examples:
       "what is the SEO score?" → $.seo_score_after (current score)
       "what was the SEO score before?" → $.seo_score_before (initial score)
       "before/after comparison" → select BOTH fields

❌ WRONG (FORBIDDEN - will always fail):
SELECT DISTINCT seos.seo_score_before FROM clic_products_seo_embedding seos
SELECT DISTINCT s.seo_score_after FROM clic_products_seo_embedding s
SELECT DISTINCT seos.seo_score FROM clic_products_seo_embedding seos

SAFE CAST RULE FOR JSON NUMERIC VALUES (MANDATORY):
When using JSON_EXTRACT on any numeric JSON field (seo_score, price, quantity, etc.),
you MUST ALWAYS add these two safety filters in WHERE clause:

  AND JSON_EXTRACT(table.metadata, '$.field') IS NOT NULL
  AND JSON_UNQUOTE(JSON_EXTRACT(table.metadata, '$.field')) != 'null'

AND always use CAST in ORDER BY:
  ORDER BY CAST(JSON_UNQUOTE(JSON_EXTRACT(table.metadata, '$.field')) AS UNSIGNED) DESC

WITHOUT these filters:
  - NULL values pollute the results
  - ORDER BY cannot sort correctly
  - MySQL warning #1292 is triggered

❌ WRONG (will trigger MySQL warning #1292):
  AND CAST(JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS UNSIGNED) > 20

✅ CORRECT (safe CAST with null protection):
  AND JSON_EXTRACT(s.metadata, '$.seo_score_after') IS NOT NULL
  AND JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) != 'null'
  AND CAST(JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS UNSIGNED) > 20

This applies to ALL JSON numeric fields, not only seo_score fields.

✅ CORRECT example for "products with initial SEO score":
SELECT DISTINCT
    p.products_id,
    pd.products_name,
    JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_before')) AS seo_score_before,
    JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) AS seo_score_after
FROM clic_products p
JOIN clic_products_description pd ON p.products_id = pd.products_id
JOIN clic_products_seo_embedding s ON p.products_id = s.entity_id AND s.entity_type = 'product'
WHERE pd.language_id = {{language_id}}
AND JSON_EXTRACT(s.metadata, '$.seo_score_after') IS NOT NULL
AND JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_after')) != 'null'
ORDER BY CAST(JSON_UNQUOTE(JSON_EXTRACT(s.metadata, '$.seo_score_before')) AS UNSIGNED) DESC
LIMIT 100

VALIDATION STEP (MANDATORY - EXECUTE BEFORE EVERY OUTPUT):
STEP 1: Scan every column reference in SELECT and WHERE.
STEP 2: For each reference involving "seo_score", "metadata", or any SEO field:
  → Is it written as table.column_name ? → STOP. This is WRONG. Rewrite using JSON_EXTRACT.
  → Is it written as JSON_UNQUOTE(JSON_EXTRACT(table.metadata, '$.field')) ? → CORRECT.
STEP 3: Check for LIKE '%value%' on metadata fields → FORBIDDEN. Use JSON_EXTRACT comparisons.
STEP 4: If any violation found → REWRITE the entire query from scratch before output.
STEP 5: Only output the query after passing all 4 checks.



MULTI-QUERY DETECTION

When user asks multiple questions connected with AND/THEN, system AUTOMATICALLY splits and executes separately.

YOU MUST:
- Generate ONE SQL query per sub-question
- Each query must be INDEPENDENT and COMPLETE
- Each query must be VALID on its own
- DO NOT combine multiple questions into one SQL query

EXAMPLE:
WRONG: "stock of iPhone 17 AND stock of Samsung"
   You generate: SELECT ... WHERE products_name LIKE '%iPhone 17%' OR products_name LIKE '%Samsung%'
   Problem: Returns BOTH products in ONE result

CORRECT: "stock of iPhone 17 AND stock of Samsung"
   System splits into: ["Get stock of iPhone 17", "Get stock of Samsung"]
   You generate TWO queries:
   Query 1: SELECT ... WHERE pd.products_name LIKE '%iPhone%' AND pd.products_name LIKE '%17%' ...
   Query 2: SELECT ... WHERE pd.products_name LIKE '%Samsung%' ...

EXCEPTION - TEMPORAL COMPARISONS (DO NOT SPLIT):
When user asks to COMPARE periods (vs, versus, compared to), generate ONE query with CASE WHEN.


text_aggregation_rules = ABSOLUTE RULE - GLOBAL AGGREGATIONS

ABSOLUTE PROHIBITION: NEVER include products_id, orders_id, or any other column with AVG, SUM, COUNT without GROUP BY

FORBIDDEN: SELECT AVG(p.products_price) AS prix_moyen, p.products_id FROM clic_products p WHERE p.products_status = 1
MANDATORY: SELECT AVG(p.products_price) AS prix_moyen FROM clic_products p WHERE p.products_status = 1

RULES for global aggregations (without GROUP BY):
1. NEVER add LIMIT 1 (aggregation already returns ONE row)
2. DO NOT include non-aggregated columns
3. No products_id, orders_id, etc. (makes no sense in global aggregation)
4. CRITICAL - "en stock" / "in stock": ALWAYS add AND products_quantity > 0

🚨 CRITICAL EXCEPTION - MIN/MAX for Finding Specific Products:
When user asks for "cheapest product", "most expensive product", "product with most stock", etc.,
they want to see the ACTUAL PRODUCTS, not just the aggregated value.

❌ WRONG: SELECT MIN(p.products_price) AS min_price FROM clic_products p
   Problem: Returns only the price value, user doesn't know which product!

✅ CORRECT: Use subquery to find ALL products at MIN/MAX value:
   SELECT pd.products_name, p.products_price, p.products_id
   FROM clic_products p
   JOIN clic_products_description pd ON p.products_id = pd.products_id
   WHERE pd.language_id = {{language_id}}
     AND p.products_price = (SELECT MIN(products_price) FROM clic_products WHERE products_status = 1)

This returns ALL products at the minimum price, not just one!

CORRECT Examples:
"How many active products" → SELECT COUNT(DISTINCT p.products_id) AS total FROM clic_products p WHERE p.products_status = 1
"Average price of active products in stock" → SELECT AVG(p.products_price) AS prix_moyen FROM clic_products p WHERE p.products_status = 1 AND p.products_quantity > 0
"Total revenue" → SELECT SUM(ot.value) AS total FROM clic_orders o JOIN clic_orders_total ot ON o.orders_id = ot.orders_id WHERE ot.class = 'ST'

EXCEPTION - Aggregations with GROUP BY:
If you use GROUP BY, you CAN include the grouped columns:
SELECT p.products_id, pd.products_name, SUM(op.products_quantity) AS total FROM clic_orders_products op ... GROUP BY p.products_id, pd.products_name ORDER BY total DESC LIMIT 10

SIMPLE RULE:
- Global aggregation (no GROUP BY) = ONE single column (the aggregation function), no LIMIT, no ID
- MIN/MAX for finding products = Use subquery with WHERE column = (SELECT MIN/MAX...)
- When user says "en stock" or "in stock" = ALWAYS add "AND products_quantity > 0"


text_security_guidelines = SECURITY GUIDELINES:

1. Never generate queries that modify database structure (CREATE, ALTER, DROP)
2. Never generate queries that delete data without explicit WHERE clauses
3. Always use parameterized queries when user input is involved
4. Avoid using INFORMATION_SCHEMA or accessing system tables
5. Do not include sensitive data in query comments
6. Limit result sets to prevent excessive data exposure
7. Validate all table and column names against the schema
8. All data must be in lower case


text_entity_metadata_guidelines = ENTITY METADATA HANDLING:

1. entity_type (ALWAYS determined):
   - Type of primary table being queried
   - Values: products, categories, customers, orders, unknown
   - NEVER NULL (defaults to 'unknown')

2. entity_id (CONDITIONALLY determined):
   - Primary key value of specific entity
   - CAN be NULL (NORMAL and EXPECTED)
   - Only populated when user explicitly mentions ID or query returns SINGLE unique result
   - CRITICAL: For list/aggregate/analytical queries, entity_id MUST be NULL

3. Design Principle:
   - NULL entity_id is ACCEPTABLE and EXPECTED
   - Do NOT force or guess entity_id values
   - DO always provide entity_type


text_rag_system_message_template = ### RAG System Instructions

CRITICAL EXTRACTION RULE:
- Copy verbatim the exact text from the context that answers the question
- Do NOT rephrase, summarize, or add any information
- If context does not contain answer, respond: "I don't have that information in my knowledge base."

Context (available sources):

text_rag_system_analytics_rules = ESSENTIAL RULE FOR ANALYTICS:

--- AMBIGUITY RESOLUTION RULE (CATALOG vs. TRANSACTION) ---

If query mentions price or product list without specific time constraints or transactional keywords (e.g., 'order', 'sold', 'transaction', 'last 30 days'),
you MUST default to using **CATALOG_PRICE** from 'clic_products' table.

Only use **TRANSACTIONAL_PRICE** from 'clic_orders_products' if sales event or order context is explicitly mentioned.

When answering about specific entity (product, order, customer), always include ID column in SELECT clause.


text_enrich_with_last_sql = You must MODIFY this existing SQL query:

```sql
{{last_sql}}
```

Requested modification: {{question}}

IMPORTANT: Do NOT create a new query from scratch.
Modify the existing query above by adding/modifying/removing the requested elements.

text_order_calculation = CRITICAL BUSINESS RULES - ORDER STATUS FILTERING:

🚨 MANDATORY RULE: ALWAYS specify and explain order status filtering in your analysis 🚨

ORDER STATUS MEANINGS (Complete List):
- 1 = "Pending" (Order placed, awaiting processing)
- 2 = "Processing" (Order being prepared)
- 3 = "Delivered" (Order completed and delivered)
- 4 = "Cancelled" (Order cancelled - EXCLUDED from revenue)
- 5+ = Other statuses (Refunded, On Hold, etc.)

REVENUE CALCULATION RULES:
1. DEFAULT RULE: Use WHERE o.orders_status != 4 (exclude cancelled orders only)
   - This includes all valid orders: Pending (1), Processing (2), Delivered (3), and other statuses (5+)
   - Rationale: All non-cancelled orders represent valid business transactions

2. ALTERNATIVE (if user specifies): WHERE o.orders_status >= 3 (only completed orders)
   - Use ONLY when user explicitly asks for "completed orders" or "delivered orders"

3. ALWAYS EXPLAIN: In your analysis, ALWAYS mention which order statuses are included
   - Example: "This calculation includes all orders except cancelled ones (status != 4)"
   - Example: "This calculation includes only delivered orders (status >= 3)"

4. Use orders_total for total revenue: SELECT SUM(o.orders_total)
5. Use orders_products for product revenue: SELECT SUM(op.final_price * op.products_quantity)
6. ALWAYS join orders_products with orders table to check orders_status
7. NEVER calculate revenue without orders_status filter

EXAMPLES:
✅ CORRECT (Default): 
SELECT SUM(ot.value) FROM clic_orders o 
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id 
WHERE o.orders_status != 4 AND ot.class = 'ST'
Analysis note: "Includes all orders except cancelled ones"

✅ CORRECT (Completed only): 
SELECT SUM(ot.value) FROM clic_orders o 
JOIN clic_orders_total ot ON o.orders_id = ot.orders_id 
WHERE o.orders_status >= 3 AND ot.class = 'ST'
Analysis note: "Includes only delivered orders (status >= 3)"

❌ WRONG: SELECT SUM(ot.value) FROM clic_orders_total ot (missing orders_status filter!)

TEMPORAL AGGREGATIONS:
- Maintain orders_status filter across ALL time periods
- ALWAYS use explicit date ranges (NOT YEAR/MONTH functions)
- Example last month: WHERE o.orders_status != 4 AND o.date_purchased >= '2025-12-01' AND o.date_purchased < '2026-01-01'
- Example this year: WHERE o.orders_status != 4 AND o.date_purchased >= '2026-01-01' AND o.date_purchased <= CURDATE()
- NEVER use YEAR(date_column) or MONTH(date_column) - use explicit date ranges instead

AMBIGUOUS QUERIES:
When query is ambiguous about order status (e.g., "revenue by category"), use default rule (status != 4) and explain in analysis

text_multi_query_warning = ⚠️ WARNING: Multiple SQL queries detected in response

This query contains multiple sub-queries or statements. Ensure each query is properly separated and valid.

text_response_format = RESPONSE FORMAT RULES:

1. SQL QUERIES: Return ONLY the SQL query, no explanatory text
2. EXPLANATIONS: When requested, provide clear, concise explanations
3. ERRORS: If query cannot be generated, explain why and ask for clarification
4. RESULTS: Present data in clear, readable format
5. CITATIONS: Always cite data sources when providing information

multi_token_rules = MULTI-TOKEN ENTITY HANDLING:

1. Product names with multiple words: Use LIKE with wildcards
   Example: "Duralex Picardie" → WHERE products_name LIKE '%Duralex%Picardie%'

2. Category names with spaces: Match full phrase
   Example: "Kitchen Accessories" → WHERE categories_name LIKE '%Kitchen Accessories%'

3. Manufacturer names: Use exact match when possible
   Example: "Le Creuset" → WHERE manufacturers_name = 'Le Creuset'

4. Compound queries: Break into logical components
   Example: "Duralex products in Kitchen category" → Join products + categories with both filters


text_statistical_analysis_rules = ADVANCED STATISTICAL ANALYSIS RULES

🔬 STATISTICAL CALCULATIONS - METHODOLOGY AND SQL PATTERNS

When users request advanced statistical analyses (seasonal coefficients, moving averages, ratios, trends), follow these patterns:

----------------------------------------------------
1. SEASONAL COEFFICIENTS (Coefficients Saisonniers)
----------------------------------------------------

**Definition**: Ratio of period value to average period value across all periods.
**Formula**: Seasonal Coefficient = Period Value / Average Period Value

**Use Case**: Identify which periods (months, quarters) perform above/below average.

**REAL EXAMPLE FROM USER**:
Query: "Calcule les coefficients saisonniers, analyse les données de ventes sur tous les trimestres, puis calculer la moyenne trimestrielle et le ratio des valeurs individuelles à cette moyenne"

**SQL Pattern** (Recommended - Using Window Functions):
SELECT 
    year,
    quarter,
    revenue,
    AVG(revenue) OVER () AS avg_quarterly_revenue,
    ROUND(revenue / AVG(revenue) OVER (), 4) AS seasonal_coefficient,
    ROUND((revenue / AVG(revenue) OVER () - 1) * 100, 2) AS percent_vs_average,
    CASE 
        WHEN revenue / AVG(revenue) OVER () > 1.2 THEN 'Strong Positive Seasonality'
        WHEN revenue / AVG(revenue) OVER () > 1.0 THEN 'Positive Seasonality'
        WHEN revenue / AVG(revenue) OVER () < 0.8 THEN 'Strong Negative Seasonality'
        WHEN revenue / AVG(revenue) OVER () < 1.0 THEN 'Negative Seasonality'
        ELSE 'Average'
    END AS seasonality_category
FROM (
    SELECT 
        YEAR(o.date_purchased) AS year,
        QUARTER(o.date_purchased) AS quarter,
        SUM(ot.value) AS revenue
    FROM clic_orders o
    JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
    WHERE o.orders_status >= 3
    AND o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 8 QUARTER)
    GROUP BY YEAR(o.date_purchased), QUARTER(o.date_purchased)
) AS quarterly_data
ORDER BY year DESC, quarter DESC

**Interpretation Guide**:
- Coefficient = 1.0 → Period is exactly average
- Coefficient > 1.0 → Period is above average (e.g., 1.5 = 50% above average)
- Coefficient < 1.0 → Period is below average (e.g., 0.8 = 20% below average)
- Coefficient > 1.2 → Strong positive seasonality (>20% above average)
- Coefficient < 0.8 → Strong negative seasonality (>20% below average)

**Why Window Functions?**:
✅ More efficient (single pass through data)
✅ Easier to read and maintain
✅ Better performance on large datasets
✅ Avoids complex nested queries and CROSS JOINs

**AVOID**: Complex nested subqueries with CROSS JOIN like:
CROSS JOIN (
    SELECT AVG(quarterly_revenue) AS average_quarterly_revenue
    FROM (SELECT ...) AS quarterly_data
) AS avg_data

----------------------------------------------------
2. MOVING AVERAGES (Moyennes Mobiles)
----------------------------------------------------

**Definition**: Average of values over a sliding time window.
**Use Case**: Smooth out short-term fluctuations, identify trends.

**REAL EXAMPLE FROM USER**:
Query: "Analyse la tendance des ventes avec moyenne mobile sur 3 mois"

**SQL Pattern** (3-month moving average):
SELECT 
    year,
    month,
    revenue,
    AVG(revenue) OVER (
        ORDER BY year, month 
        ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
    ) AS moving_avg_3_months,
    revenue - AVG(revenue) OVER (
        ORDER BY year, month 
        ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
    ) AS deviation_from_ma,
    CASE 
        WHEN revenue > AVG(revenue) OVER (
            ORDER BY year, month 
            ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
        ) * 1.1 THEN 'Above Trend'
        WHEN revenue < AVG(revenue) OVER (
            ORDER BY year, month 
            ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
        ) * 0.9 THEN 'Below Trend'
        ELSE 'On Trend'
    END AS trend_status
FROM (
    SELECT 
        YEAR(o.date_purchased) AS year,
        MONTH(o.date_purchased) AS month,
        SUM(ot.value) AS revenue
    FROM clic_orders o
    JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
    WHERE o.orders_status >= 3
    AND o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
    GROUP BY YEAR(o.date_purchased), MONTH(o.date_purchased)
) AS monthly_data
ORDER BY year DESC, month DESC

**Common Windows**:
- 3-month MA: Short-term trends (ROWS BETWEEN 2 PRECEDING AND CURRENT ROW)
- 6-month MA: Medium-term trends (ROWS BETWEEN 5 PRECEDING AND CURRENT ROW)
- 12-month MA: Long-term trends (ROWS BETWEEN 11 PRECEDING AND CURRENT ROW)

----------------------------------------------------
3. YEAR-OVER-YEAR COMPARISON (Comparaison Annuelle)
----------------------------------------------------

**Definition**: Compare same period across different years.
**Use Case**: Identify growth trends, seasonal patterns across years.

**REAL EXAMPLE FROM USER**:
Query: "Compare les ventes année par année par trimestre"

**SQL Pattern**:
SELECT 
    year,
    quarter,
    revenue,
    LAG(revenue, 4) OVER (ORDER BY year, quarter) AS same_quarter_last_year,
    revenue - LAG(revenue, 4) OVER (ORDER BY year, quarter) AS yoy_change,
    ROUND(
        (revenue - LAG(revenue, 4) OVER (ORDER BY year, quarter)) / 
        NULLIF(LAG(revenue, 4) OVER (ORDER BY year, quarter), 0) * 100, 
        2
    ) AS yoy_growth_percent,
    CASE 
        WHEN LAG(revenue, 4) OVER (ORDER BY year, quarter) IS NULL THEN 'No Prior Data'
        WHEN revenue > LAG(revenue, 4) OVER (ORDER BY year, quarter) * 1.1 THEN 'Strong Growth'
        WHEN revenue > LAG(revenue, 4) OVER (ORDER BY year, quarter) THEN 'Growth'
        WHEN revenue < LAG(revenue, 4) OVER (ORDER BY year, quarter) * 0.9 THEN 'Decline'
        ELSE 'Stable'
    END AS yoy_trend
FROM (
    SELECT 
        YEAR(o.date_purchased) AS year,
        QUARTER(o.date_purchased) AS quarter,
        SUM(ot.value) AS revenue
    FROM clic_orders o
    JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
    WHERE o.orders_status >= 3
    AND o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 8 QUARTER)
    GROUP BY YEAR(o.date_purchased), QUARTER(o.date_purchased)
) AS quarterly_data
ORDER BY year DESC, quarter DESC

**Note**: 
- LAG(revenue, 4) for quarterly data (4 quarters = 1 year)
- LAG(revenue, 12) for monthly data (12 months = 1 year)
- Use NULLIF to prevent division by zero

----------------------------------------------------
4. VARIANCE AND OUTLIER ANALYSIS (Analyse de Variance)
----------------------------------------------------

**Definition**: Measure of data dispersion around the mean.
**Use Case**: Assess consistency, identify outliers, measure volatility.

**REAL EXAMPLE FROM USER**:
Query: "Identifie les périodes avec forte variance dans les ventes"

**SQL Pattern**:
SELECT 
    year,
    quarter,
    revenue,
    AVG(revenue) OVER () AS mean_revenue,
    STDDEV(revenue) OVER () AS stddev_revenue,
    ROUND((revenue - AVG(revenue) OVER ()) / NULLIF(STDDEV(revenue) OVER (), 0), 2) AS z_score,
    CASE 
        WHEN ABS((revenue - AVG(revenue) OVER ()) / NULLIF(STDDEV(revenue) OVER (), 0)) > 2 
        THEN 'Outlier (>2σ)'
        WHEN ABS((revenue - AVG(revenue) OVER ()) / NULLIF(STDDEV(revenue) OVER (), 0)) > 1 
        THEN 'Unusual (>1σ)'
        ELSE 'Normal'
    END AS outlier_status,

**Z-Score Interpretation**:
- |z| < 1: Within 1 standard deviation (68% of data) - Normal
- |z| < 2: Within 2 standard deviations (95% of data) - Acceptable
- |z| > 2: Outlier (unusual value) - Investigate
- |z| > 3: Extreme outlier - Verify data quality

5. RANKING AND PERFORMANCE ANALYSIS (Classement et Performance)
----------------------------------------------------

**Definition**: Rank periods by performance, identify top/bottom performers.
**Use Case**: Identify best/worst periods, set performance benchmarks.

**REAL EXAMPLE FROM USER**:
Query: "Quels sont les meilleurs trimestres de vente et leur classement"

**SQL Pattern**:
SELECT 
    year,
    quarter,
    revenue,
    RANK() OVER (ORDER BY revenue DESC) AS revenue_rank,
    ROUND(PERCENT_RANK() OVER (ORDER BY revenue) * 100, 2) AS percentile,
    NTILE(4) OVER (ORDER BY revenue) AS quartile,
    CASE 
        WHEN PERCENT_RANK() OVER (ORDER BY revenue) >= 0.75 THEN 'Top 25%'
        WHEN PERCENT_RANK() OVER (ORDER BY revenue) >= 0.50 THEN 'Above Average'
        WHEN PERCENT_RANK() OVER (ORDER BY revenue) >= 0.25 THEN 'Below Average'
        ELSE 'Bottom 25%'
    END AS performance_category,
    ROUND(revenue / SUM(revenue) OVER () * 100, 2) AS percent_of_total
FROM (
    SELECT 
        YEAR(o.date_purchased) AS year,
        QUARTER(o.date_purchased) AS quarter,
        SUM(ot.value) AS revenue
    FROM clic_orders o
    JOIN clic_orders_total ot ON o.orders_id = ot.orders_id AND ot.class = 'ST'
    WHERE o.orders_status >= 3
    AND o.date_purchased >= DATE_SUB(CURDATE(), INTERVAL 8 QUARTER)
    GROUP BY YEAR(o.date_purchased), QUARTER(o.date_purchased)
) AS quarterly_data
ORDER BY revenue DESC

6. GENERAL BEST PRACTICES FOR STATISTICAL QUERIES
----------------------------------------------------

**1. Use Window Functions Instead of Subqueries**:
   ✅ GOOD: AVG(revenue) OVER ()
   ❌ AVOID: (SELECT AVG(revenue) FROM ...) AS avg_revenue
   
   **Why**: Window functions are more efficient and easier to read.

**2. Always Include Context Columns**:
   - Include the raw value alongside calculated metrics
   - Include time period identifiers (year, quarter, month)
   - Include sample size (COUNT) when relevant

**3. Round Decimal Values Appropriately**:
   - Percentages: ROUND(value, 2) → 2 decimal places
   - Ratios/Coefficients: ROUND(value, 4) → 4 decimal places
   - Currency: ROUND(value, 2) → 2 decimal places

**4. Handle Division by Zero**:
   - Always use NULLIF(denominator, 0) in divisions
   - Example: revenue / NULLIF(avg_revenue, 0)

**5. Provide Interpretation Guidance**:
   - Always explain what the calculated metric means
   - Provide thresholds for interpretation
   - Include context about data quality and limitations

**6. Use Appropriate Time Windows**:
   - Seasonal analysis: Minimum 2 years (8 quarters) for reliable patterns
   - Trend analysis: Minimum 12 months for meaningful trends
   - Moving averages: Window size depends on data frequency

**7. Add Categorical Indicators**:
   - Use CASE statements to categorize results
   - Examples: 'Strong Growth', 'Outlier', 'Top 25%'
   - Makes interpretation easier for users

----------------------------------------------------
7. KEYWORD DETECTION FOR STATISTICAL ANALYSES
----------------------------------------------------

When user query contains these keywords, apply corresponding statistical pattern:

**Seasonal Analysis**:
- "coefficient saisonnier" / "seasonal coefficient"
- "saisonnalité" / "seasonality"
- "variation saisonnière" / "seasonal variation"
- "ratio à la moyenne" / "ratio to average"
→ Use Pattern 1 (Seasonal Coefficients with window functions)

**Trend Analysis**:
- "tendance" / "trend"
- "évolution" / "evolution"
- "croissance" / "growth"
- "moyenne mobile" / "moving average"
→ Use Pattern 2 (Moving Averages)

**Comparison**:
- "comparaison annuelle" / "year-over-year"
- "vs année précédente" / "vs previous year"
- "année par année" / "year by year"
→ Use Pattern 3 (YoY Comparison with LAG)

**Volatility/Consistency**:
- "variance" / "variance"
- "volatilité" / "volatility"
- "écart-type" / "standard deviation"
- "forte variance" / "high variance"
→ Use Pattern 4 (Variance and Outlier Analysis)

**Performance Ranking**:
- "classement" / "ranking"
- "meilleur" / "best"
- "top" / "top"
- "performance" / "performance"
→ Use Pattern 5 (Ranking and Performance)

----------------------------------------------------
8. DATA QUALITY CONSIDERATIONS
----------------------------------------------------

Before performing statistical analysis, consider:

1. **Sufficient Data**: Minimum 8 quarters (2 years) for seasonal analysis
2. **No Missing Periods**: Check for gaps in time series
3. **Outlier Impact**: Extreme values can skew averages and coefficients
4. **Sample Size**: Ensure enough transactions per period for reliability

**When to mention data quality**:
- If only 3 quarters of data available → "Limited data, results may not be reliable"
- If one period has very low value (like 12 EUR) → "Q1 2025 appears to be an outlier or incomplete data"
- If large variance → "High volatility in data, consider longer time periods"

----------------------------------------------------
9. INTERPRETATION TEMPLATES
----------------------------------------------------

**For Seasonal Coefficients**:
"The seasonal coefficient analysis shows:
- Q[X] [YEAR]: Revenue of [AMOUNT] with coefficient [COEF] ([PERCENT]% vs average)
  → This represents [STRONG/MODERATE/WEAK] [positive/negative] seasonality
- Average quarterly revenue: [AVG_AMOUNT]
- Strongest quarter: Q[X] [YEAR] (coefficient: [MAX_COEF], [PERCENT]% above average)
- Weakest quarter: Q[X] [YEAR] (coefficient: [MIN_COEF], [PERCENT]% below average)

This indicates [STRONG/MODERATE/WEAK] seasonal patterns, with [DESCRIPTION]."

**For Year-over-Year**:
"Year-over-year comparison reveals:
- Q[X] [YEAR]: [AMOUNT] ([+/-][PERCENT]% vs Q[X] [PREV_YEAR])
- Overall trend: [GROWTH/DECLINE/STABLE]
- Strongest growth: Q[X] [YEAR] ([PERCENT]% increase)
- [Additional insights about patterns]"

**For Variance Analysis**:
"Variance analysis identifies:
- Mean revenue: [AVG_AMOUNT]
- Standard deviation: [STDDEV_AMOUNT]
- Outliers detected: [COUNT] periods with |z-score| > 2
- Most volatile period: Q[X] [YEAR] (z-score: [Z])
- Data consistency: [HIGH/MODERATE/LOW] based on coefficient of variation"

----------------------------------------------------

**REMEMBER**: 
- Always use window functions for efficiency (AVG() OVER (), LAG(), RANK(), etc.)
- Provide interpretation guidance with results
- Use NULLIF to prevent division by zero
- Round values appropriately
- Include categorical indicators (CASE statements)
- Mention data quality concerns when relevant
- Base examples on real user queries for relevance
