Frequently Asked Questions
What SQL dialects does this formatter support?
This formatter supports Standard SQL, MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), MariaDB, and BigQuery. Each dialect uses dialect-specific parsing for accurate formatting of vendor-specific syntax like backtick identifiers (MySQL), double-quoted identifiers (PostgreSQL), and square bracket identifiers (SQL Server).
Does formatting change the meaning of my SQL?
No. Formatting only changes whitespace and optionally the case of SQL keywords. The logical structure and execution plan of your query remain identical. Minification similarly only removes unnecessary whitespace and comments.
Why should I format my SQL queries?
Formatted SQL is easier to read, review, and debug. Consistent formatting helps teams maintain code quality, makes complex queries with multiple JOINs and subqueries more understandable, and is considered a best practice in professional development.
Is my SQL data safe?
Yes. All formatting happens entirely in your browser using JavaScript. No SQL queries are sent to any server. Your data never leaves your machine.
Can I format stored procedures and DDL statements?
Yes. The formatter handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, DROP, and other DDL/DML statements. When using dialect-specific modes like PL/SQL or T-SQL, stored procedure syntax is also supported.
