Frequently Asked Questions

What is SQL formatting?▼

SQL formatting adds proper indentation, line breaks, and consistent capitalization to SQL queries. It transforms hard-to-read single-line queries into well-structured, readable code — essential for maintaining complex database queries.

Should SQL keywords be uppercase?▼

Uppercase SQL keywords (SELECT, FROM, WHERE, JOIN) is a widely followed convention that improves readability by visually distinguishing keywords from table/column names. Most style guides recommend it, though SQL itself is case-insensitive.

Does formatting change how SQL executes?▼

No, SQL formatting is purely cosmetic. Adding whitespace, newlines, and changing keyword case doesn't affect query execution or performance. The database engine ignores all formatting when parsing and executing queries.
