Which SQL dialects are supported?

The formatter supports standard SQL, MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), and PL/SQL (Oracle). Select your dialect for the most accurate formatting.

Will formatting change the behavior of my query?

No. Formatting only changes whitespace, indentation, and keyword casing. The logical behavior and results of the query remain identical.

Why Format SQL?

Formatted SQL is dramatically easier to read and debug. Proper formatting reveals the logical structure of a query at a glance: which tables are joined, what conditions filter the results, and how the output is sorted or grouped. During code reviews, formatted SQL helps reviewers spot issues quickly. Consistent formatting across a team reduces cognitive load and makes database code maintainable.

SQL Formatting Best Practices

Put each major clause (SELECT, FROM, WHERE, JOIN) on its own line.
Indent columns and conditions under their parent clause.
Use uppercase for SQL keywords for visual distinction.
Align JOIN conditions for readability.
Break long WHERE clauses into multiple lines with AND/OR at the start of each line.
