Basic Knowledge

What Does SQL Formatting Align?

SQL formatting aligns the capitalization of keywords like SELECT and WHERE, line breaks between clauses, and indentation based on nesting depth according to consistent rules. The query behavior remains unchanged; only readability improves.

Why Format SQL?

A long SQL query written on a single line is difficult to follow—it's hard to identify where conditions end and joins begin. Adding line breaks and indentation by clause makes it easy to quickly grasp the query's intent during code reviews and troubleshooting.
