Frequently asked questions

Why should I format SQL?

Formatted SQL is dramatically easier to read, debug, and review. Consistent formatting also helps team members understand queries without needing to parse dense one-liners.

Does formatting change query behavior?

No. SQL formatting is purely cosmetic. Whitespace and newlines do not affect how the query is parsed or executed.

What is the difference between SQL dialects?

Each database has extensions and syntax differences. MySQL uses backtick quoting; PostgreSQL uses double-quote; SQL Server uses square brackets. The formatter adapts to the selected dialect.

How do I make a slow SQL query faster?

Use EXPLAIN ANALYZE to see the query plan. Add indexes on columns used in WHERE, JOIN, and ORDER BY clauses. Avoid SELECT * and reduce the number of rows processed.
