Generator / Database

SQL Create Table Generator

Design table schemas visually, validate column rules as you type, and export ready-to-run CREATE TABLE SQL for the database you actually use.

Live schema builder

Add, reorder, and configure columns without hand-writing DDL.

Dialect-aware output

Switch between MySQL, PostgreSQL, SQLite, and SQL Server instantly.

Copy or download

Export clean .sql files or copy to your clipboard in one click.

Schema editor

Set your table name, choose a SQL dialect, then shape columns in place.

Uses AUTO_INCREMENT and backtick identifiers.

Generated SQL

Preview updates as your schema changes.

CREATE TABLE `orders` (
  `id` BIGINT AUTO_INCREMENT NOT NULL,
  `customer_email` VARCHAR(255) NOT NULL,
  `status` VARCHAR(50) NOT NULL DEFAULT 'pending',
  `total_amount` DECIMAL(10,2) NOT NULL DEFAULT 0,
  `created_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  UNIQUE (`customer_email`)
);

Validation checklist

  • Validates empty or duplicate column names before export.
  • Warns when auto increment is paired with a non-integer type.
  • Handles precision and scale for DECIMAL / NUMERIC fields.
  • Generates dialect-specific primary key and default syntax.

How to use this generator

  1. 1. Pick your target database engine so the SQL syntax matches production.
  2. 2. Enter a table name and define each column's type, nullability, uniqueness, and defaults.
  3. 3. Review live validation messages, then copy the output or download a .sql migration starter.

Best for

Quick CRUD scaffolding before you write migrations.
Teaching teammates the differences between SQL dialects.
Drafting database schemas during planning or discovery.
Generating shareable starter DDL for docs and tickets.

Why this tool is useful

Visual DDL drafting

You can sketch a table structure quickly without stopping to remember exact CREATE TABLE syntax for every database engine.

Cross-dialect comparison

Switching between MySQL, PostgreSQL, SQLite, and SQL Server makes differences in quoting, identity columns, and defaults obvious immediately.

Safer starter SQL

Live validation catches missing names, duplicate columns, and questionable auto-increment setups before the SQL leaves your browser.

Handy for planning and docs

It is useful for tickets, architecture notes, migration planning, and quick prototyping when you need something concrete to share fast.

Frequently asked questions

Does this tool create the table in my real database?

No. It only generates SQL in your browser. Nothing is run against your database unless you copy the SQL and execute it yourself.

Can I generate composite primary keys?

Yes. Mark more than one column as a primary key and the generator will output a table-level PRIMARY KEY constraint, except for SQLite autoincrement cases where it has to stay a single INTEGER PRIMARY KEY.

How are default values handled?

Numeric values stay numeric, common timestamp functions are kept as SQL expressions, booleans are normalized per dialect, and other values are emitted as quoted SQL strings.

Is my schema data uploaded anywhere?

No. Everything happens client-side. Your schema, defaults, and generated SQL stay in the browser unless you decide to copy or download them.
