Frequently Asked Questions
SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) are conventionally written in uppercase to visually distinguish them from table names, column names, and aliases which are typically lowercase. This is a style convention, not a language requirement — SQL is case-insensitive for keywords. Consistent casing makes queries faster to scan and easier to understand, particularly in long or complex queries with many joins and conditions.
Yes. The SQL formatter handles standard ANSI SQL that is common to all major database engines. Dialect-specific syntax (PostgreSQL's :: casting, MySQL's backtick identifiers, SQL Server's [] identifiers, etc.) is passed through unchanged. The formatter focuses on keyword casing and clause indentation which is universal across dialects.
Yes. Paste an entire SQL script with multiple statements separated by semicolons, or a stored procedure body, and the formatter will process the whole input. Each major clause (SELECT, FROM, WHERE, JOIN, ORDER BY, etc.) will be placed on its own line and AND/OR conditions will be indented for readability.
