MySQL syntax checker

Paste a statement to catch missing commas, unclosed quotes, and similar issues. FlashKit does not connect to MySQL.

MariaDB / Postgres / BigQuery dialects will false-positive. Format first if the query is unreadable.

How to Use

  1. Paste one statement at a time when possible.
  2. Run the check and fix the first reported issue.
  3. Format the query so reviewers can read it.
  4. EXPLAIN it on a replica — not in this tab.

Key Features

  • Local syntax pass
  • No database credentials collected
  • No account
  • Works with the SQL formatter
