Common questions

Does formatting change execution?

No. Whitespace is insignificant to the database, though string literals are preserved exactly.

Which dialects are supported?

Common MySQL, PostgreSQL and standard SQL syntax. Vendor-specific extensions may format imperfectly.

Can it format stored procedures?

Simple bodies format well. Complex procedural code with delimiters may need manual cleanup.
