What Is SQL EXPLAIN?
The EXPLAIN statement provides information about how MySQL or PostgreSQL executes a query. It shows the query execution plan, including table scan methods, join types, index usage, and estimated row counts. EXPLAIN ANALYZE actually executes the query and adds timing information.
