Slow MySQL orders query
Load a MySQL query with joins, filters, ordering, and pagination so SQLito can suggest rewrite and composite-index ideas.
MySQL diagnostics
- Use EXPLAIN FORMAT=JSON for an estimated plan without executing the query.
- Use EXPLAIN ANALYZE only for safe statements because it executes the query.
- SHOW INDEX output and row counts improve index advice.
- ANALYZE TABLE updates optimizer statistics and should be treated as a maintenance command.
Privacy and review notes
- SQLito suggests rewrites and index ideas; it does not execute SQL.
- Redact literals, credentials, hostnames, emails, customer data, table names, and index names.
- Review index changes for write overhead and composite index order before applying them.
MySQL optimizer FAQ
Does SQLito run my MySQL query?
No. SQLito reviews text and pasted diagnostics. It does not connect to or modify your database.
Which MySQL diagnostic is safest to paste?
An estimated EXPLAIN FORMAT=JSON plan is the safest first diagnostic. EXPLAIN ANALYZE executes the statement.
