Examples
Basic SELECT Query
Format a basic SQL query with joins and conditions
select u.id,u.name,u.email,p.title from users u join posts p on u.id=p.user_id where u.active=1 order by u.name;
SELECT u.id,
u.name,
u.email,
p.title
FROM users u
JOIN posts p ON u.id = p.user_id
WHERE u.active = 1
ORDER BY u.name;
Complex Query with Subquery
Format complex query with subqueries and aggregations
SELECT customers.customer_name,orders.order_date,(SELECT COUNT(*) FROM order_items WHERE order_items.order_id = orders.order_id) as item_count FROM customers INNER JOIN orders ON customers.customer_id = orders.customer_id WHERE orders.order_date >= '2023-01-01';
SELECT customers.customer_name,
orders.order_date,
(SELECT COUNT(*)
FROM order_items
WHERE order_items.order_id = orders.order_id) AS item_count
FROM customers
INNER JOIN orders ON customers.customer_id = orders.customer_id
WHERE orders.order_date >= '2023-01-01';
Multiple Statements
Format multiple SQL statements
CREATE TABLE users (id INT PRIMARY KEY,name VARCHAR(255) NOT NULL,email VARCHAR(255) UNIQUE);INSERT INTO users (name,email) VALUES ('John Doe','john@example.com'),('Jane Smith','jane@example.com');
CREATE TABLE users (
id INT PRIMARY KEY,
name VARCHAR(255) NOT NULL,
email VARCHAR(255) UNIQUE
);
INSERT INTO users (name, email)
VALUES ('John Doe', 'john@example.com'),
('Jane Smith', 'jane@example.com');

Frequently Asked Questions
What SQL dialects are supported?
The formatter supports standard SQL syntax and is compatible with MySQL, PostgreSQL, SQL Server, Oracle, and SQLite. It handles common keywords, functions, and operators across these platforms.
Can I customize the formatting style?
Yes, you can configure indentation (spaces/tabs), keyword case (upper/lower), comma placement, line breaks for JOINs, and alignment options for a consistent coding style.
Does it validate SQL syntax?
The tool performs basic syntax validation including bracket matching, incomplete statements, and structural issues. For comprehensive validation, use a dedicated SQL parser.
How does minification work?
Minification removes unnecessary whitespace and comments while preserving SQL functionality. This is useful for reducing query size in production environments.
What about complex queries with CTEs and window functions?
The formatter handles Common Table Expressions (WITH clauses), window functions (OVER, PARTITION BY), and other advanced SQL features with proper indentation and formatting.
