SQL Syntax Validator

This tool allows you to check and validate your SQL queries for correctness against a chosen dialect, enhancing code quality and reducing errors.

Why Use the SQL Syntax Validator?

Even a small typo can break your database scripts or cause unexpected runtime errors. Our SQL Syntax Validator helps you:

  • Catch Mistakes Early – spot missing keywords, unbalanced parentheses, or invalid functions before deployment

  • Maintain Code Quality – enforce consistent syntax across your team’s queries

  • Support Multiple Dialects – validate against MySQL, PostgreSQL, SQL Server (T-SQL), Oracle (PL/SQL), SQLite, BigQuery, and more

  • Save Debugging Time – instantly pinpoint the exact location and nature of syntax errors

Key Benefits

  • Dialect-Aware Validation
    Choose your target database engine and ensure your SQL conforms to its specific syntax rules—no more guesswork or manual lookups.

  • Error Highlighting & Suggestions
    See highlighted errors in your query and read concise tips on how to fix them, from missing commas to incorrect function usage.

  • No Sign-up Required
    Validate your code directly in the browser—100% free, private, and secure.

How It Works

  2. Paste your SQL query into the input box.

  3. Click Validate Syntax to run the checker.

  4. Review the validation result panel for errors or a green “Syntax is Valid” confirmation.
