SQL Schema Generator

Generate complete database schemas from a simple text description — create multiple related tables with foreign keys automatically.

About SQL Schema Generator

Designing a complete database schema from scratch involves writing CREATE TABLE statements for every entity, choosing appropriate data types for each column, defining primary keys and foreign keys, and adding indexes. This tool accelerates the process by inferring data types from column names, automatically adding ID columns, detecting foreign key relationships from naming conventions (user_id → references users), and generating all the boilerplate code you need to get started.

Simply describe your entities in plain format — "table: col1, col2, col3" — and the generator creates a complete, well-structured SQL schema. Column names like id, created_at, email, and price are automatically given appropriate types. Columns ending in _id are given INT type and can be used to establish foreign key relationships in the generated schema.

FAQ

How does the generator infer data types?
The generator uses column name patterns: id → INT/BIGINT/UUID, email → VARCHAR(255), name/title/slug → VARCHAR(255), body/content/description → TEXT, price/amount/total → DECIMAL(10,2), created_at/updated_at/deleted_at → TIMESTAMP, is_*/active/published/enabled → TINYINT(1)/BOOLEAN, *_id → INT (foreign key).
Are foreign key constraints generated?
Columns ending in _id are given INT type matching the id type. Full FOREIGN KEY constraints with REFERENCES can be added manually after generation, as the generator doesn't know with certainty which table each _id column references without additional context.
