SQL Syntax Checker

Check whether SQL parses in the selected dialect before you run it.

A syntax pass does not verify tables, permissions or execution results.

Check Oracle SQL and PL/SQL blocks, procedures, functions, and packages. This does not compile code in a database.

Choose a database and select Check syntax.

Fix the first reported issue, then check again.

Supports Oracle/PLSQL, Oracle-compatible Tibero syntax, MySQL, PostgreSQL, SQLite, and SQL Server. Version-specific extensions and successful execution are not guaranteed. Named :binds need no values; render HQML/FreeMarker templates to SQL before checking. SQL is never executed.

Select your database
Choose Oracle, Tibero, MySQL, PostgreSQL, SQLite or SQL Server. The selected dialect can change how the same statement is interpreted.
Check rendered SQL
Paste the actual SQL and run the check. Separate statements with semicolons, and expand template tags into SQL before checking.
Inspect where parsing stopped
Jump to the reported line and column, then inspect nearby commas, brackets and operators. Fix the issue and check again; verify execution separately in your database.

A worked example

A missing value after WHERE

Start with: SELECT id, name FROM users WHERE status = ;
Check the result: Use the issue location to check for the missing value after =.

The marker shows where parsing stopped. Unsupported syntax may also be reported, so confirm the dialect.
