1

Why SQL formatting matters

Readable SQL is easier to debug, review and maintain. Proper formatting helps developers understand joins, filters, grouping, ordering and complex query logic faster.

2

Format SELECT queries clearly

Place selected columns on separate lines when queries are long. Keep FROM, JOIN, WHERE, GROUP BY and ORDER BY clauses visually separated so the query structure is easy to scan.

3

Use consistent indentation

Indent nested queries, CASE statements and JOIN conditions consistently. Consistency is more important than a single perfect style because teams need predictable formatting.

4

Avoid very long single-line SQL

Single-line SQL is hard to review and easy to break during changes. Formatting SQL before code review reduces mistakes and improves collaboration.
