How to Generate SQL CREATE TABLE Schemas Online

Writing standard SQL Data Definition Language (DDL) by hand can be prone to syntax errors and dialect inconsistencies. Our visual schema generator lets you define table columns, data types, primary keys, and unique constraints effortlessly.

Choose between PostgreSQL, MySQL, and SQLite to automatically adapt type definitions (like SERIAL vs AUTO_INCREMENT vs INTEGER PRIMARY KEY) and generate ready-to-execute SQL.

Key Features for Database Architects

  • Multi-Dialect Support: Correctly maps auto-increment primary keys and timestamp defaults for PostgreSQL, MySQL, and SQLite.
  • Instant Seed Data Generation: Option to generate realistic sample INSERT INTO statements for rapid testing and prototyping.
  • 100% Client-Side Engine: Your database schema design remains private in your local browser memory.
  • One-Click Copy: Copy production-ready SQL scripts to paste directly into pgAdmin, DBeaver, phpMyAdmin, or migration scripts.

Frequently Asked Questions (FAQ)

What is the difference between PostgreSQL SERIAL and MySQL AUTO_INCREMENT?
In PostgreSQL, SERIAL creates an integer column linked to an auto-incrementing sequence object. In MySQL, the column is defined as INT AUTO_INCREMENT PRIMARY KEY. Our tool handles this syntax automatically.
Can I use this generated SQL in Laravel or Django migrations?
Yes! The generated CREATE TABLE statements follow standard ANSI SQL conventions and can be executed in raw SQL database migrations or used as reference schemas.
