Write, debug, and tune SQL
SQL Copilot helps you write, debug, review, and improve SQL across major database platforms. It adapts queries to the correct SQL dialect, checks joins, NULL handling, dates, duplicates, and output grain, and helps make UPDATE, DELETE, MERGE, and schema changes safer with preview and validation steps. It can also analyze performance issues using execution-plan evidence, support BI and data-modeling SQL, and explain fixes clearly without claiming to run queries or inspect databases it cannot access.
