Se déclenche avec \"sous-agent DB\", \"database agent\", \"SQL agent\", \"agent base de données\", \"query agent\", \"agent qui requête\", \"text-to-SQL agent\", \"NL2SQL\". Also triggers on \"database query agent\", \"text to SQL subagent\".\n---\n\n# Database Query Sub-Agent\n\n## Cas d'usage\n\nDéléguer à ce sous-agent toute interrogation DB depuis un agent parent : NL2SQL (question → SQL), analyse de données complexes, BI assistée par IA, drill-down conversationnel multi-tour. Ne pas utiliser pour des mutations — ce sous-agent est en lecture seule par défaut.\n\n---\n\n## Workflow (10 étapes)\n\n### 1. Validation des inputs\n\nRecevoir et valider **avant** toute génération de SQL :\n\n```python\nrequired = [\"question\", \"connection.db_type\", \"connection.host\", \"connection.database\"]\n# Tester la connexion : ping + SELECT 1\n# Si échec → retourner immédiatement errors=[{\"type\": \"connection_error\", ...}]\n```\n\nDefaults : `read_only=True`, `max_rows=1000`, `timeout_s=30`.\n\n---\n\n### 2. Découverte du schéma\n\nSi `schema` non fourni, l'inférer automatiquement :\n\n```sql\n-- PostgreSQL / MySQL\nSELECT table_name, column_name, data_type, is_nullable\nFROM information_schema.columns\nWHERE table_schema = 'public'\nORDER BY table_name, ordinal_position;\n\n-- SQLite\nSELECT name, sql FROM sqlite_master WHERE type='table';\n\n-- SQL Server\nSELECT t.name, c.name, tp.name, c.is_nullable\nFROM sys.tables t\nJOIN sys.columns c ON t.object_id = c.object_id\nJOIN sys.types tp ON c.user_type_id = tp.user_type_id;\n```\n\nConstruire un DDL simplifié (max ~2 000 tokens) à injecter dans le prompt de génération.\n\n---\n\n### 3. NL → SQL (génération)\n\nPrompt structuré :\n\n```\nSchéma DDL :\n<DDL des tables pertinentes uniquement>\n\nQuestion : <question utilisateur>\nDialecte : <db_type>\nContraintes : lecture seule, LIMIT max_rows\n\nRègles :\n- Préférer les CTEs aux sous-requêtes imbriquées\n- Alias explicites sur toutes les colonnes ambiguës\n- Pas de SELECT * sur tables volumineuses\n- Exemples few-shot si disponibles en session_context\n```\n\nCritères de sélection des tables pertinentes : similarité sémantique entre la question et les noms de tables/colonnes (embedding cosine > 0.7, ou matching de mots-clés en fallback).\n\n---\n\n### 4. Validation avant exécution\n\n```python\nimport sqlglot\n\ndef validate_query(sql: str, db_type: str, schema: dict, read_only: bool) -> list[str]:\n    errors = []\n    # 1. Parse syntaxique\n    try:\n        parsed = sqlglot.parse_one(sql, dialect=db_type)\n    except sqlglot.errors.ParseError as e:\n        errors.append(f\"syntax_error: {e}\")\n        return errors\n\n    # 2. Vérifier colonnes et tables vs schéma\n    for table in parsed.find_all(sqlglot.exp.Table):\n        if table.name not in schema[\"tables\"]:\n            errors.append(f\"unknown_table: {table.name}\")\n\n    # 3. Bloquer mutations si read_only\n    if read_only:\n        forbidden = (sqlglot.exp.Drop, sqlglot.exp.Delete,\n                     sqlglot.exp.Update, sqlglot.exp.Insert,\n                     sqlglot.exp.Create, sqlglot.exp.AlterTable)\n        for node in parsed.walk():\n            if isinstance(node, forbidden):\n                errors.append(f\"mutation_blocked: {type(node).__name__}\")\n    return errors\n```\n\nEn cas d'erreur de validation : retourner sans exécuter, inclure la requête invalide dans `errors[].query`.\n\n---\n\n### 5. Exécution sécurisée\n\n```python\nfrom sqlalchemy import create_engine, text\nfrom sqlalchemy.pool import NullPool\n\nengine = create_engine(conn_url, poolclass=NullPool,\n                       connect_args={\"connect_timeout\": 5})\n\nwith engine.connect() as conn:\n    # Lecture seule au niveau transaction\n    conn.execute(text(\"SET TRANSACTION READ ONLY\"))          # PostgreSQL / MySQL\n    # SQL Server : utiliser un login sans droits DML\n\n    # Timeout\n    conn.execute(text(f\"SET statement_timeout = {timeout_s * 1000}\"))  # PostgreSQL ms\n\n    # LIMIT automatique si absent\n    if \"LIMIT\" not in sql.upper() and db_type != \"sqlserver\":\n        sql += f\" LIMIT {max_rows}\"\n    elif db_type == \"sqlserver\" and \"TOP\" not in sql.upper():\n        sql = sql.replace(\"SELECT\", f\"SELECT TOP {max_rows}\", 1)\n\n    result = conn.execute(text(sql))\n    rows = [dict(r) for r in result.fetchmany(max_rows + 1)]\n    truncated = len(rows) > max_rows\n    return rows[:max_rows], truncated\n```\n\n---\n\n### 6. Traitement des résultats\n\nSérialisation sûre pour JSON :\n\n```python\nimport math\nfrom decimal import Decimal\nfrom datetime import date, datetime\n\ndef serialize_row(row: dict) -> dict:\n    out = {}\n    for k, v in row.items():\n        if v is None:\n            out[k] = None\n        elif isinstance(v, (datetime, date)):\n            out[k] = v.isoformat()\n        elif isinstance(v, Decimal):\n            out[k] = float(v)\n        elif isinstance(v, float) and math.isnan(v):\n            out[k] = None  # NaN non serializable JSON\n        elif isinstance(v, bytes):\n            out[k] = v.hex()\n        else:\n            out[k] = v\n    return out\n```\n\nCalculer les stats pour colonnes numériques : `{min, max, mean, std, null_count, p25, p50, p75}`.\n\n---\n\n### 7. Analyse du plan d'exécution\n\nLancer `EXPLAIN` si `row_count > 10 000` ou `execution_time_s > 2` :\n\n```sql\nEXPLAIN (ANALYZE, BUFFERS, FORMAT JSON) <votre requête>;  -- PostgreSQL\nEXPLAIN FORMAT=JSON <votre requête>;                       -- MySQL\n```\n\nSignaux d'alerte à détecter dans le plan :\n- `Seq Scan` sur table > 100 000 lignes sans `WHERE` sélectif\n- `Nested Loop` avec `cost > 10 000`\n- `Hash Join` avec spill sur disque (`\"Disk Spills\" > 0`)\n- Cardinalité estimée / réelle ratio > 10× (statistiques obsolètes)\n\nInclure dans `optimization_hints` uniquement si gain estimé > 50 %.\n\n---\n\n### 8. Dialectes SQL — différences clés\n\n| Feature | PostgreSQL | MySQL | SQLite | SQL Server | BigQuery |\n|---------|-----------|-------|--------|------------|---------|\n| Limite | `LIMIT n` | `LIMIT n` | `LIMIT n` | `TOP n` | `LIMIT n` |\n| Date now | `NOW()` | `NOW()` | `datetime('now')` | `GETDATE()` | `CURRENT_TIMESTAMP` |\n| Regex | `~` / `~*` | `REGEXP` | `LIKE` seulement | `LIKE` / `PATINDEX` | `REGEXP_CONTAINS` |\n| JSON | `->` `->>`  | `JSON_EXTRACT` | `json_extract()` | `JSON_VALUE` | `JSON_EXTRACT_SCALAR` |\n| ILIKE | oui | non (insensible par défaut) | non | `COLLATE` | `LOWER()` |\n| CTE récursive | oui | ≥ 8.0 | ≥ 3.35 | oui | oui |\n\nPour MongoDB : traduire en pipeline d'agrégation (`$match` → `$group` → `$project`), pas de SQL.\n\n---\n\n### 9. Contexte conversationnel multi-tour\n\n```python\nclass QuerySession:\n    def __init__(self):\n        self.history: list[dict] = []  # [{\"question\", \"sql\", \"row_count\", \"columns\"}]\n        self.last_result_columns: list[str] = []\n        self.last_filter: dict = {}\n\n    def resolve_anaphora(self, question: str) -> str:\n        \"\"\"Remplacer 'eux', 'les mêmes', 'parmi ceux-là' par le contexte précédent.\"\"\"\n        if self.history and any(p in question.lower() for p in [\"eux\", \"ceux-là\", \"les mêmes\"]):\n            last = self.history[-1]\n            return f\"Parmi les résultats de '{last['question']}' ({last['sql']}), {question}\"\n        return question\n```\n\nPasser `session_context` (sérialisé) dans chaque call et le retourner mis à jour dans l'output.\n\n---\n\n### 10. Génération du rapport\n\nRetourner systématiquement :\n- **explanation** : 2–3 phrases, langage métier, pas de jargon SQL\n- **visualization_suggestion** : `\"bar_chart\"` (comparaison catégorielle), `\"line_chart\"` (série temporelle), `\"table\"` (> 5 colonnes mixtes), `\"pie_chart\"` (répartition ≤ 6 catégories), `\"scatter\"` (corrélation numérique)\n- **follow_up_questions** : 2–3 questions de drill-down générées par LLM sur la base des résultats\n\n---\n\n## Interface contractuelle\n\n**Input :**\n```python\n{\n  \"question\": str,           # Obligatoire — NL ou SQL direct\n  \"schema\": dict | None,     # Optionnel — inféré si absent\n  \"connection\": {\n    \"db_type\": str,          # \"postgresql\"|\"mysql\"|\"sqlite\"|\"sqlserver\"|\"bigquery\"|\"mongodb\"\n    \"host\": str,\n    \"port\": int | None,\n    \"database\": str,\n    \"username\": str,\n    \"password\": str,         # Jamais loggué\n    \"ssl\": bool              # Défaut: True\n  },\n  \"read_only\": bool,         # Défaut: True\n  \"max_rows\": int,           # Défaut: 1000\n  \"timeout_s\": int,          # Défaut: 30\n  \"session_context\": dict | None,\n  \"explain_results\": bool    # Défaut: True\n}\n```\n\n**Output :**\n```python\n{\n  \"query\": str,\n  \"results\": list[dict],\n  \"row_count\": int,\n  \"execution_time_s\": float,\n  \"explanation\": str,\n  \"stats\": {\"col\": {\"min\": float, \"max\": float, \"mean\": float, \"null_count\": int}},\n  \"optimization_hints\": list[str],\n  \"visualization_suggestion\": str,\n  \"follow_up_questions\": list[str],\n  \"session_context\": dict,\n  \"errors\": list[{\"type\": str, \"message\": str, \"query\": str}],\n  \"truncated\": bool\n}\n```\n\n**Dépendances Python :**\n```\nsqlalchemy>=2.0\nsqlglot>=25.0\npsycopg2-binary>=2.9\npymysql>=1.1\npyodbc>=5.0\npandas>=2.2\npydantic>=2.0\n```\n\n---\n\n## Garde-fous et anti-patterns\n\n**Ne jamais faire :**\n- Concaténer des inputs utilisateur directement dans le SQL → toujours `text(:param)` + `bindparams`\n- Retourner des credentials dans `errors` ou `explanation`\n- Exécuter sans timeout configuré — les requêtes analytiques peuvent saturer la DB\n- Ignorer `truncated=True` dans la réponse — l'agent parent doit en être informé\n- Deviner une table/colonne inconnue — demander clarification ou retourner une erreur explicite\n\n**Pièges courants :**\n- `EXPLAIN ANALYZE` exécute réellement la requête sur PostgreSQL — ne l'utiliser qu'en lecture\n- SQLite ne supporte pas `SET TRANSACTION READ ONLY` — utiliser un fichier en mode `uri=true&mode=ro`\n- BigQuery facture à la lecture de données scannées — toujours ajouter `LIMIT` et vérifier les partitions\n- Les types `DECIMAL`/`NUMERIC` Python ne sont pas sérialisables JSON nativement — convertir en `float`\n- Sur SQL Server, `TOP n` doit précéder les colonnes, pas en fin de requête\n\n**Bonnes pratiques 2026 :**\n- Utiliser `sqlglot.transpile(sql, read=source_dialect, write=target_dialect)` pour la portabilité inter-SGBD\n- Stocker les schémas inférés en cache (TTL 5 min) — éviter l'introspection à chaque appel\n- Pour les embeddings de colonnes (sélection de tables pertinentes), utiliser un modèle léger local (`all-MiniLM-L6-v2`) plutôt qu'un appel LLM externe\n- Logger le hash SHA-256 de chaque requête exécutée pour l'audit — jamais les credentials\n- Tester la génération NL→SQL avec un jeu de questions de référence (golden set) avant déploiement\n","tagline":"Sous-agent spécialisé dans les requêtes base de données — SQL generation, exécution et analyse de résultats.
