About SQL Dialect Conversion

What is SQL Dialect Conversion?

Different database systems use slightly different SQL syntax, known as "dialects." For example, MySQL uses backticks for identifiers, while PostgreSQL uses double quotes. Oracle might use different date functions than SQL Server. Our SQL dialect converter automatically translates queries between these systems, saving developers time when migrating databases or working with multiple systems.

Supported Database Dialects

  • MySQL
  • PostgreSQL
  • Oracle
  • SQL Server
  • SQLite
  • BigQuery

Why Convert SQL Dialects?

  • Migration: Move applications between database systems
  • Compatibility: Work with multiple database backends
  • Learning: Understand syntax differences between databases
  • Development: Test queries across different platforms
  • Integration: Connect systems using different databases

How to Use This Tool

  1. Select the source database dialect from the dropdown menu (MySQL, PostgreSQL, Oracle, etc.)
  2. Choose the target database dialect you want to convert to
  3. Paste your SQL query in the input field
  4. Configure formatting options like reindentation and keyword case if needed
  5. Click "Convert & Format" to transform your SQL
Conversion Examples 
MySQL → PostgreSQL:
LIMIT 10 → LIMIT 10

Oracle → SQL Server:
SYSDATE → GETDATE()

SQLite → MySQL:
AUTOINCREMENT → AUTO_INCREMENT

SQL Dialect Conversion Best Practices

  • Test Thoroughly: Always test converted queries in the target environment

  • Performance: Review query performance after conversion, as syntax may affect execution plans
  • Features: Some advanced database features may not have direct equivalents
