SQL formatting conventions

This formatter applies the most common SQL style conventions:

  • Keywords in UPPERCASE — SELECT, FROM, WHERE, JOIN, etc. Distinguishes reserved words from identifiers and table/column names.
  • Major clauses on new lines — SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT each start on their own line.
  • JOIN conditions indented — ON clauses are indented under the JOIN keyword.
  • Subqueries indented — nested SELECTs are indented inside parentheses.

Why SQL formatting matters

Production SQL queries are often written in tight windows, copied from ORMs, or extracted from query logs — all of which produce minified, hard-to-read SQL. Formatting is the first step before:

  • Code review of database migrations.
  • Debugging a slow query by finding which subquery or JOIN needs an index.
  • Documenting complex queries in technical specs.
  • Converting raw query logs into readable queries for analysis.
