SQL Syntax Checker
Check Oracle, compatible Tibero SQL, PL/SQL, and other dialects.
Check SQL syntax before running itSQL is checked in this browser, without uploading or saving it.
No database connectionCheck Oracle SQL and PL/SQL blocks, procedures, functions, and packages. This does not compile code in a database.

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.
Complete guide
How to use SQL Syntax Checker
When to use it
Check Oracle SQL/PLSQL, Oracle-compatible Tibero syntax, MySQL, PostgreSQL, SQLite, or SQL Server in your browser. Supports named binds, error line/column navigation, and formatting before checking.
01
Three-step workflow
- 1
Choose Oracle/PLSQL, Tibero (Oracle compatible), MySQL, PostgreSQL, SQLite, or SQL Server.
- 2
Paste SQL or PL/SQL and select Check syntax or press Ctrl/⌘ + Enter. Named binds such as :departmentId do not need values.
- 3
Go to the first reported line/column, edit, and check again. SQL, PL/SQL/tbPSM examples and Format & check are also available.
02
What to enter and check
Check up to 100,000 characters. Finish a PL/SQL block with END; and place an optional script separator / on its own line. Semicolons inside blocks do not split the script into separate units. Editing input or switching databases clears results; running checks can be cancelled.
Checks Oracle SQL/PLSQL and Oracle-compatible Tibero SQL/tbPSM grammar. Database compilation, declared variables, types, tables, columns, function arguments, and permissions are not verified. Check Tibero-specific features and database-version extensions separately. Render HQML/FreeMarker templates to SQL first; SQL*Plus/tbSQL client commands are outside this checker’s scope.
Practical example
Oracle and Tibero modes can check SELECT NVL(name, 'Unknown') FROM employees WHERE department_id = :departmentId; . Leaving WHERE department_id = ; reports an issue. DECLARE v_count NUMBER := 0; BEGIN v_count := v_count + 1; END; is parsed as one PL/SQL block.
How to read the result
Checks Oracle SQL/PLSQL and Oracle-compatible Tibero SQL/tbPSM grammar. Database compilation, declared variables, types, tables, columns, function arguments, and permissions are not verified. Check Tibero-specific features and database-version extensions separately. Render HQML/FreeMarker templates to SQL first; SQL*Plus/tbSQL client commands are outside this checker’s scope.
05
Before you use the result
- SQL is never uploaded, saved, or executed, and no database connection is made.
- Tibero uses Oracle-compatible grammar. Database compilation, types, and permissions are not verified. Render HQML templates to SQL first.
