What is SQL Formatting?

SQL formatting means organizing your SQL queries so they are:

• Easy to read
• Easy to understand
• Easy to debug

Step 1: Understand Basic SQL Structure

Every SQL query follows a basic structure:

SELECT column_name
FROM table_name
WHERE condition;

Step 2: Start with a Messy Query

select id,name from users where age>18;

This works — but it’s not readable.

Step 3: Apply Basic Formatting Rules

Rule 1: Use Uppercase for Keywords

SELECT id, name FROM users WHERE age > 18;

Rule 2: Break into Multiple Lines

SELECT id, name
FROM users
WHERE age > 18;

Rule 3: Add Indentation

SELECT
  id,
  name
FROM users
WHERE age > 18;

Step 4: Format a Real Query

Messy Query

select u.id,u.name,o.amount from users u join orders o on u.id=o.user_id where u.status='active' and o.amount>100;

Clean Query

SELECT
  u.id,
  u.name,
  o.amount
FROM users u
JOIN orders o
  ON u.id = o.user_id
WHERE u.status = 'active'
  AND o.amount > 100;

Step 5: Use a SQL Formatter Tool

Simple SQL Formatting Rules for Beginners

• Always use uppercase SQL keywords
• Use one line per clause
• Use indentation for readability
• Avoid long single-line queries
• Use meaningful table aliases

Common Beginner Mistakes

❌ Writing Everything in One Line

Hard to read and debug.

❌ Mixing Uppercase and Lowercase

Creates inconsistency.

❌ No Indentation

Makes queries confusing.

Practice Example

Try formatting this query:

select * from orders where amount>200 and status='completed';

Expected Output

SELECT *
FROM orders
WHERE amount > 200
  AND status = 'completed';
