About SQL Query Analyzer
The SQL Query Analyzer parses raw database queries and extracts meaningful metadata. It automatically identifies all referenced tables, selected columns, functions used, and execution operations, which is incredibly useful for database auditing and query optimization.
How to Use
Real-World Examples
Auditing Table Access
Paste a massive stored procedure to quickly generate a list of every single table it interacts with.
SELECT u.id, o.total FROM users u JOIN orders o ON u.id = o.user_id
Tables Detected: `users`, `orders`. Columns: `u.id`, `o.total`, `o.user_id`.
Best Practices
- Use this tool to verify that your queries are not accidentally referencing deprecated tables before deploying code.
Pro Tips
The analyzer handles CTEs (Common Table Expressions) and subqueries gracefully, mapping their dependencies accurately.
