How it works

Column definitions become CREATE TABLE syntax with primary keys, nullability, defaults, unique constraints, and indexes in dialect-specific order. Identifiers are quoted when needed; the script is not executed.

  • Explicit constraints make schema intent reviewable.
  • Dialect controls identity and auto-increment syntax.

Worked example

Users Table with Constraints
Generate a CREATE TABLE statement for a users table
Input
											Table name: users
Columns: [{"name":"id","type":"SERIAL","primaryKey":true},{"name":"email","type":"VARCHAR(255)","nullable":false,"unique":true},{"name":"name","type":"VARCHAR(100)"},{"name":"created_at","type":"TIMESTAMP","defaultValue":"NOW()"}]
Output
												CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email VARCHAR(255) NOT NULL UNIQUE,
  name VARCHAR(100),
  created_at TIMESTAMP DEFAULT NOW()
);

When to use this

Prototype schemas, teaching examples, and migration scaffolds generate table DDL.

Edge cases

  • Reserved column names need quoting.
  • CURRENT_TIMESTAMP is an expression, not a quoted string default.
  • Foreign keys need existing referenced tables and compatible types.
