Usage Examples

Example 1: Basic Query Formatting

Before

SELECT id, name, address FROM users WHERE age > 25 AND city = 'New York' ORDER BY name ASC

After

SELECT id, name, address
FROM users
WHERE age > 25
  AND city = 'New York'
ORDER BY name ASC;

Example 2: Complex Query with Joins and Subqueries

Input

SELECT u.id, u.name, a.address, o.order_id, o.order_date FROM users u JOIN addresses a ON u.id = a.user_id JOIN orders o ON u.id = o.user_id WHERE u.age > 25 AND a.city = 'New York' AND o.status = 'completed' ORDER BY u.name ASC, o.order_date DESC

Output

SELECT u.id, u.name, a.address, o.order_id, o.order_date
FROM users u
JOIN addresses a ON u.id = a.user_id
JOIN orders o ON u.id = o.user_id
WHERE u.age > 25
  AND a.city = 'New York'
  AND o.status = 'completed'
ORDER BY u.name ASC, o.order_date DESC;

Example 3: Formatting with Custom Indentation

Input

SELECT * FROM users WHERE (age > 25 AND city = 'New York') OR (age < 18 AND city = 'Los Angeles')

Output (with 4 spaces indentation)

SELECT *
FROM users
WHERE (age > 25 AND city = 'New York')
   OR (age < 18 AND city = 'Los Angeles');
