Frequently asked questions

Which SQL dialects are supported?▾

The formatter works on standard SQL shared by MySQL, PostgreSQL, SQL Server, SQLite and Oracle — including backtick, double-quote and [bracket] identifiers, :: casts and -- or /* */ comments.

Can formatting break my query?▾

No. Only whitespace and the letter case of keywords change. String literals, identifiers, numbers and comments are copied exactly, so the query means the same thing.

How are subqueries and joins laid out?▾

Each clause (SELECT, FROM, JOIN, WHERE, GROUP BY…) starts on its own line, select columns go one per line, AND/OR conditions break onto new lines and subqueries are indented inside their parentheses.

What does minify do?▾

It removes comments and collapses the query onto a single line with minimal spaces — handy for logs, config files or embedding SQL in code.
