Production Drizzle Kit Ready

Includes instant drizzle.config.ts recipes, migration commands, and TypeScript type inferencing for zero-friction schema workflows.

Technical Reference & Architecture Guide

Drizzle ORM Schema to SQL CREATE TABLE DDL Generator — Reference Guide

Translate Drizzle ORM pgTable, mysqlTable, and sqliteTable definitions back into executable SQL CREATE TABLE migration scripts.

Key Parameters & Controls

SQL Dialect & Driver TargetEnum (PostgreSQL / pgTable | MySQL / mysqlTable | SQLite / sqliteTable)

Selects the target database engine to determine dialect-specific DDL syntax, data type mappings (e.g., TIMESTAMP WITH TIME ZONE vs DATETIME, JSONB vs JSON), identifier quote characters, and constraint rules.

Default: PostgreSQL / pgTable
Constraint Placement StrategyEnum (Table-level Named Constraints | Inline Column Constraints)

Controls whether primary keys, unique constraints, and foreign key references are emitted as inline column definitions or explicit table-level CONSTRAINT clauses at the bottom of each table definition.

Default: Table-level Named Constraints
Index & Enum Emission StrategyEnum (Standalone DDL Statements | Embedded Schema Clauses)

Specifies whether custom PostgreSQL enums (pgEnum) and table indexes are emitted as standalone CREATE TYPE and CREATE INDEX DDL statements or consolidated into table declarations where supported.

Default: Standalone DDL Statements
Idempotency & PreamblesEnum (CREATE TABLE IF NOT EXISTS | Strict CREATE TABLE | Include DROP TABLE IF EXISTS)

Appends safe existence checks (IF NOT EXISTS) or generates prepended DROP TABLE IF EXISTS ... CASCADE; statements for clean migration replay scripts.

Default: CREATE TABLE IF NOT EXISTS

Pro Tips & Best Practices

When converting multi-table schemas

When converting multi-table schemas with foreign key references, ensure parent tables precede child tables in the generated SQL script, or configure the generator to emit foreign keys as separate ALTER TABLE ... ADD CONSTRAINT commands to eliminate dependency cycle errors.

Drizzle ORM updated composite primary

Drizzle ORM updated composite primary keys and index definitions from object notation (table) => ({ pk: primaryKey(...) }) to array returns (table) => [primaryKey(...), index(...)]. Ensure your schema inputs accommodate both formats for seamless compatibility.

When utilizing pgEnum in PostgreSQL

When utilizing pgEnum in PostgreSQL schemas, emit standalone CREATE TYPE ddl blocks wrapped in DO $$ BEGIN ... EXCEPTION WHEN duplicate_object THEN null; END $$; guards to guarantee idempotent migration execution without naming conflicts.

Common Gotchas & Troubleshooting

Table creation fails with relation does not exist error during foreign key resolution

Foreign key constraints require the referenced table and primary key columns to exist beforehand. Reorder table definitions in your schema or separate foreign key constraints into post-creation ALTER TABLE statements.

Data type mismatch or unsupported modifier when converting between database engines

Ensure column definitions match the selected dialect. Features like PostgreSQL jsonb, identity columns, or native UUID generation (gen_random_uuid()) must be mapped to appropriate dialect primitives (such as JSON or CHAR(36)) when targeting MySQL or SQLite.

Frequently Asked Questions

How does the generator translate Drizzle ORM foreign key references and cascade rules?▼

When parsing .references(() => table.column, { onDelete: 'cascade', onUpdate: 'set null' }), the converter translates the expression directly to SQL REFERENCES table(column) ON DELETE CASCADE ON UPDATE SET NULL clauses, maintaining complete relational integrity.

Are composite primary keys and multi-column indexes fully supported?▼

Yes. Composite constraints defined in Drizzle table config callbacks—such as primaryKey({ columns: [table.colA, table.colB] }) or index('idx_user_email').on(table.tenantId, table.email)—are accurately mapped to table-level PRIMARY KEY and standalone CREATE INDEX statements.

Can I convert multiple tables and PostgreSQL enums from a single schema file?▼

Yes. Paste your entire schema file containing multiple pgTable, mysqlTable, or sqliteTable exports. The tool parses each table definition, resolves dependencies, and outputs a complete, sequential SQL DDL migration file.

What is the advantage of using this web tool over running drizzle-kit generate?▼

While drizzle-kit generate requires a configured Node.js environment, drizzle.config.ts, and local npm package installations, this browser-based tool generates raw SQL DDL instantaneously with zero installation, zero server upload, and 100% client-side privacy.
