SQL Formatting: How to Write Clean Queries

Messy SQL queries are hard to maintain and optimize. Learn indentation standards and query styling techniques for clean code.

Why Format Your SQL?

Database queries can quickly grow into massive blocks of nested joins and subqueries. If formatted poorly, debugging takes twice as long. Structured spacing and uppercase keywords make the database logic transparent.

Formatting Standards

  • Always capitalize SQL keywords like SELECT, FROM, WHERE, and JOIN.
  • Put each table join and filter criteria on a new line.
  • Indent subqueries consistently.
