SQL Formatting Examples
Before Formatting (Compressed SQL)
select u.id,u.name,p.title from users u join profiles p on u.id=p.user_id where u.active=1 and p.public=true order by u.created_at desc limit 10;After Formatting (Beautified SQL)
SELECT u.id, u.name, p.title FROM users u JOIN profiles p ON u.id = p.user_id WHERE u.active = 1 AND p.public = true ORDER BY u.created_at DESC LIMIT 10;
