Can it help with complex multi-table joins?

Yes, it specifically analyzes join logic to suggest more efficient join orders and identify where indexes can best assist in reducing table scans.

Which database engines does this skill support?

The SQL Query Optimizer provides general SQL optimization principles and patterns applicable to most major engines including PostgreSQL, MySQL, SQL Server, and SQLite.

Is an EXPLAIN plan required for analysis?

While not strictly required, providing the output of an EXPLAIN statement allows the skill to provide much more accurate and effective performance recommendations.

Does the skill automatically apply changes to my database?

No, it generates optimized code and index recommendations. You should review and test these suggestions in a staging environment before manually applying them.
