What SQL dialects are supported?

The formatter supports standard SQL plus dialect-specific features for PostgreSQL, MySQL, SQL Server, SQLite, Oracle, and several others. Select the dialect to get formatting rules that match your database's syntax.

Should SQL keywords be uppercase or lowercase?

It's a matter of convention. Uppercase keywords (SELECT, FROM, WHERE) make keywords visually distinct from identifiers, which improves readability. Lowercase keywords are common in some teams and ORMs. The formatter lets you choose.

Does the formatter handle stored procedures?

Yes. The formatter handles stored procedures, functions, and other procedural SQL constructs including variable declarations, IF/ELSE blocks, and loops. The indentation reflects the control flow structure.

Can I format multiple queries at once?

Yes. The formatter handles multiple SQL statements separated by semicolons. Each statement is formatted independently and the semicolons are preserved.

Does the formatter change the query's logic?

No. The formatter only changes whitespace and keyword casing. The query's logic, table names, column names, values, and operators are preserved exactly as they were. The formatted query produces the same results as the original.
