Database Query Generator

Generate a database query from this request:

REQUEST:
[Natural language description of what data is needed]

DATABASE SCHEMA:
[Table structures and relationships]

DATABASE TYPE:
[PostgreSQL / MySQL / MongoDB / etc.]

GENERATE:
{
  "query": "The actual query",
  "query_type": "SELECT | INSERT | UPDATE | DELETE",
  "parameters": ["value1", "value2"],
  "explanation": "What this query does",
  "estimated_impact": "rows affected or returned"
}

SAFETY CHECKS:
- Add LIMIT if SELECT without limit
- Warn if UPDATE/DELETE without WHERE
- Note if query might be slow (missing indexes)

If query cannot be safely generated:
{
  "error": "Cannot generate safe query",
  "reason": "explanation",
  "manual_review_needed": true
}
