Introduction

This online SQL minifier tool helps you compress and optimize your SQL code efficiently. It’s perfect for reducing file size and improving the readability of complex SQL queries by removing unnecessary whitespace.

How to Use This Tool

  1. Paste your SQL code directly into the editor or type it in.
  2. Click the Minify button to compress your SQL code.
  3. After minifying, you can:
    • Download the optimized result.
    • Save or share it using a unique link.
    • Sign in with Google or GitHub to save your minified SQL for future use.

What is SQL?

SQL (Structured Query Language) is the standard language for managing and interacting with relational databases. It can perform a wide range of tasks, including:

  • Inserting, searching, updating, and deleting database records.
  • Optimizing and maintaining database performance.
  • Defining database schema and managing data access control.

SQL is widely used in applications that require robust data storage and retrieval, making it an essential tool for developers and database administrators.

SQL Syntax

      
SELECT employee.first_name,
       employee.last_name,
       call.start_time,
       call.end_time,
       call_outcome.outcome_text
FROM employee
INNER JOIN CALL ON call.employee_id = employee.id
INNER JOIN call_outcome ON call.call_outcome_id = call_outcome.id
ORDER BY call.start_time ASC;

Examples

Before minified

      
SELECT
    first_name,
    last_name,
    employees.department_id,
    departments.department_id,
    department_name
FROM
    employees
        INNER JOIN
    departments ON departments.department_id = employees.department_id
WHERE
    employees.department_id IN (1 , 2, 3);

After minified

      
SELECT first_name, last_name, employees.department_id, departments.department_id, department_name FROM employees INNER JOIN departments ON departments.department_id=employees.department_id WHERE employees.department_id IN (1 , 2, 3);
