I need to fix my SQL query. Let me query the categorical columns separately and properly. ```json { "action": "tool_call", "reasoning": "The UNION ALL syntax failed. I'll query stance distribution first, then country separately. Starting with stance from the fighters table.", "tool": "query_sql", "args": { "sql": "SELECT stance, COUNT(*) as frequency, ROUND(COUNT(*) * 100.0 / (SELECT COUNT(*) FROM raw.fighters WHERE stance IS NOT NULL), 2) as percentage FROM raw.fighters WHERE stance IS NOT NULL GROUP BY stance ORDER BY frequency DESC", "purpose": "Get distribution of fighter stances" } } ```
