Frequently Asked Questions (FAQ)
help_outlineWhich SQL dialects are supported?
Our formatter supports standard SQL (ANSI), which covers the vast majority of queries for MySQL, PostgreSQL, SQLite, and Microsoft SQL Server.
help_outlineIs there a limit to the query size?
You can format queries up to several thousand lines, though for optimal performance, we recommend formatting one script at a time.
help_outlineDoes this tool validate my SQL syntax?
While our tool beautifies the code, it does not execute it. We recommend using your database management tool to check for schema-specific errors.
help_outlineCan I use this for complex nested queries?
Absolutely! The SQL Formatter is specifically designed to handle deeply nested subqueries and complex JOIN operations that are often the hardest to read.
