Frequently Asked Questions
Common questions about SQL formatting and our online SQL beautifier.
What SQL dialects are supported?
Our SQL formatter supports Standard SQL, MySQL, PostgreSQL, SQLite, and SQL Server dialects. Each dialect handles specific syntax differences like backtick quoting in MySQL, dollar-quoted strings in PostgreSQL, and bracket identifiers in SQL Server.
Is my SQL query sent to a server?
No. All SQL formatting happens entirely in your browser using JavaScript. Your queries never leave your device, making it safe to format sensitive database queries containing production data or credentials.
Can I format complex queries with JOINs and subqueries?
Yes. The formatter handles complex SQL including multi-table JOINs, nested subqueries, CTEs (WITH clauses), window functions, CASE expressions, and stored procedures. Each is properly indented for readability.
What is SQL minification?
SQL minification removes unnecessary whitespace, newlines, and comments from your query to create the most compact version. This is useful for embedding SQL in application code, API calls, or reducing query string length.
Does the formatter change my query logic?
No. The formatter only changes whitespace, indentation, and optionally keyword casing. Your query logic, table names, column names, values, and structure remain completely unchanged.
