FAQ
Which SQL errors can this fix?▾
It catches missing/extra commas, unmatched parentheses/quotes, incorrect keyword usage, missing aliases, wrong string delimiters, semicolon issues, JOIN syntax problems, and database-specific function mismatches. It does not validate table or column names against a live schema.
Why does the IDE selection matter?▾

No. Everything runs in your browser. Your SQL never leaves your machine.
