Conversion is rule-based and focuses on common syntax. Review complex queries before production use.
About SQL Dialect Converter & Analyzer
SQL Dialect Converter & Analyzer combines lightweight SQL migration assistance with practical static checks. Convert common syntax between MySQL or MariaDB, PostgreSQL and SQL Server, or inspect a query for referenced tables, JOINs, CTEs and risky statements without connecting to a database.
How to use SQL Dialect Converter & Analyzer
- 1
Choose Dialect Converter or SQL Analyzer.

Paste SQL and convert common identifiers, date functions, auto-increment syntax, data types and row-limit syntax.

Review warnings such as UPDATE or DELETE without WHERE, DROP, TRUNCATE, SELECT * and multiple statements.
Tips for better results
- Treat dialect conversion as a migration helper rather than a full SQL compiler; stored procedures and vendor-specific extensions still need manual review.
- Run converted SQL in a test environment before using it in production.
- The analyzer is static and heuristic. It does not inspect schema statistics, execution plans or live indexes.

Which file formats can I use?
