SQL Formatting Best Practices
Consistent Keyword Capitalization
Use uppercase for SQL keywords (e.g., SELECT, FROM, WHERE) to make them stand out. This helps in quickly identifying the structure of the query. For example:
SELECT column1, column2 FROM table_name WHERE condition;
Proper Indentation
If your query becomes long, use indentation to separate different parts of the query. Use tabs or spaces to indent the query. For example:
SELECT * FROM table_name WHERE condition
Logical Line Breaks
Break long lines at logical points, such as after commas or before AND/OR operators. This makes it easier to read and understand the query. For example:
SELECT user_id, user_name, email, created_at FROM users WHERE status = 'active' AND last_login >= '2024-01-01' OR user_type = 'admin' ORDER BY created_at DESC;
Meaningful Aliases
Use meaningful aliases for tables and columns to make the query more readable. Avoid using single-letter aliases unless they are widely accepted (e.g., t for table). For example:
SELECT user.id AS user_id, user.name AS user_name, order.total AS order_total FROM users AS user JOIN orders AS order ON user.id = order.user_id WHERE order.status = 'shipped';
