Validate SQL syntax before treating a query as ready for a database

SQL syntax differs between database dialects such as PostgreSQL, MySQL, SQLite and SQL Server. A validator can identify parsing problems before a query reaches a live database.

Syntactic validity does not prove that tables exist, permissions are correct or business logic is safe.

Useful SQL-validation workflows

  • Review queries during development.
  • Catch obvious syntax errors in generated SQL.
  • Compare whether a statement parses under a selected dialect.

What validation cannot guarantee

  • It does not prove the query returns the intended rows.
  • It does not make unsafe dynamic SQL secure.
  • Test destructive queries against appropriate non-production data first.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
