Database Schema:
{schema}

Context: {context}
Question: {question}

Generate a valid SQL query that answers the question. 
Only return the SQL query, no explanations.

CRITICAL RULES:
- Use proper SQL syntax
- Include appropriate WHERE clauses
- Column aliases MUST use underscores, NEVER spaces (e.g., "total_earnings" NOT "Total Earnings")
- Limit results to 100 rows unless specifically asked for more
- Use proper JOINs when needed
- Only use SELECT statements (no INSERT, UPDATE, DELETE, etc.)
- Use table and column names exactly as they appear in the schema
- Add appropriate ORDER BY clauses for meaningful results
- Use aggregate functions (COUNT, SUM, AVG, etc.) when appropriate
- Handle NULL values appropriately
- Use NOW() for current date/time, NOT CURDATE()
- For date formatting, use CONCAT(YEAR(date), '-', LPAD(MONTH(date), 2, '0')) instead of DATE_FORMAT()

COLUMN ALIAS RULES:
- ALWAYS use underscores in column aliases
- NEVER use spaces in column aliases
- Examples: "total_earnings", "month", "agent_name", "commission_amount"
- WRONG: "Total Earnings", "Month", "Agent Name"
- RIGHT: "total_earnings", "month", "agent_name"

Examples:
- "Show me all deals" → SELECT * FROM deals LIMIT 100
- "What's the total commission" → SELECT SUM(commission_amount) as total_commission FROM deals
- "List agents by performance" → SELECT agent_name, COUNT(*) as deals_count, SUM(commission_amount) as total_commission FROM deals GROUP BY agent_name ORDER BY total_commission DESC
- "earnings by month" → SELECT CONCAT(YEAR(date), '-', LPAD(MONTH(date), 2, '0')) as month, SUM(amount) as total_earnings FROM earning WHERE date >= DATE_SUB(NOW(), INTERVAL 3 MONTH) GROUP BY CONCAT(YEAR(date), '-', LPAD(MONTH(date), 2, '0')) ORDER BY month
