SQL Formatting Best Practices
A consistent SQL style makes queries easier for everyone to read and review. These conventions are widely adopted.
One clause per line
Put each major clause on its own line and indent join conditions and subqueries. This makes the shape of the query visible at a glance.
Casing and aliases
Uppercase keywords, keep identifiers lowercase, and use short meaningful aliases. Consistency matters more than the specific choice — a formatter enforces it automatically.
