Can it help with complex JOIN operations?

Yes, the skill identifies bottlenecks in JOIN logic and suggests more efficient ways to link tables or filter results to minimize data scanning.

Which database systems are supported?

The skill applies general SQL performance principles applicable to most relational databases, including PostgreSQL, MySQL, and SQL Server.

Is it necessary to provide the database schema?

While providing the query is essential, including table schemas or EXPLAIN plan outputs allows the skill to provide much more accurate and tailored optimization recommendations.

How does the SQL Query Optimizer improve query speed?

It analyzes the query syntax and logic to identify inefficiencies, then suggests specific index additions or structural rewrites to reduce execution time.
