Frequently Asked Questions
Which SQL dialects are supported?
The formatter handles standard SQL syntax that is common across most databases including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It focuses on keyword formatting and indentation rather than dialect-specific features.
Does this tool validate my SQL?
No, this tool formats SQL for readability but does not validate syntax or check for errors. It will format whatever input you provide, regardless of whether it is valid SQL.
Are string literals preserved?
Yes. Single-quoted strings and double-quoted identifiers are preserved as-is. The formatter will not modify content inside quotes or incorrectly uppercase text within string literals.
What does minify do?
Minify collapses the entire query to a single line and normalizes all whitespace to single spaces. This is useful when you need a compact query for logging, configuration files, or embedding in code.
