Name: SQL to Prisma Schema Converter
Author: Trools

Convert PostgreSQL, MySQL, and SQLite CREATE TABLE DDL statements into Prisma Schema models.

Presets:

SQL DDL (CREATE TABLE)PostgreSQL • MySQL • SQLite

CREATE TABLE users (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  email VARCHAR(255) UNIQUE NOT NULL,
  full_name VARCHAR(100),
  role VARCHAR(20) DEFAULT 'CUSTOMER',
  created_at TIMESTAMPTZ DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE categories (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  slug VARCHAR(100) UNIQUE NOT NULL,
  name VARCHAR(100) NOT NULL
);

CREATE TABLE products (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  title VARCHAR(200) NOT NULL,
  price DECIMAL(10, 2) NOT NULL,
  stock INT DEFAULT 0,
  category_id UUID NOT NULL,
  created_at TIMESTAMPTZ DEFAULT CURRENT_TIMESTAMP,
  CONSTRAINT fk_category FOREIGN KEY (category_id) REFERENCES categories (id) ON DELETE CASCADE
);

CREATE TABLE orders (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  user_id UUID NOT NULL,
  total_amount DECIMAL(12, 2) NOT NULL,
  status VARCHAR(50) DEFAULT 'PENDING',
  created_at TIMESTAMPTZ DEFAULT CURRENT_TIMESTAMP,
  CONSTRAINT fk_user FOREIGN KEY (user_id) REFERENCES users (id)
);

CREATE TABLE order_items (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  order_id UUID NOT NULL,
  product_id UUID NOT NULL,
  quantity INT NOT NULL DEFAULT 1,
  unit_price DECIMAL(10, 2) NOT NULL,
  CONSTRAINT fk_order FOREIGN KEY (order_id) REFERENCES orders (id) ON DELETE CASCADE,
  CONSTRAINT fk_product FOREIGN KEY (product_id) REFERENCES products (id)
);

Generated Prisma Schema

Understanding SQL to Prisma Schema Converter

When migrating existing SQL databases or scaffolding an ORM layer, writing schema.prisma models by hand from SQL DDL is tedious and error-prone. This converter parses CREATE TABLE statements from PostgreSQL, MySQL, and SQLite, accurately translating column types, primary keys, nullability, unique constraints, and foreign key relations into clean, idiomatic Prisma schema models.

Modern web workflows demand tools that operate without arbitrary paywalls, intrusive tracking scripts, or data latency. With Trools, all underlying computational algorithms, formatting routines, and state manipulations run directly inside your client-side JavaScript V8 engine. Because no payload is transmitted across external networks, SQL to Prisma Schema Converter offers zero-latency client-side execution that guarantees proprietary keys, database schemas, and bearer tokens never traverse public network pipes.

Whether you are performing quick operational checks during production deployments, validating client deliverables, or automating repetitive daily calculations, SQL to Prisma Schema Converter streamlines your workflow with real-time reactive feedback, cross-platform responsiveness, and one-click copy and download functionality.

Privacy Guarantee: The Trools architecture strictly guarantees that all operations performed within SQL to Prisma Schema Converter execute in local browser memory. Zero analytics tracking, zero session cookies, and zero server uploads. Your data remains strictly yours.

How to use the SQL to Prisma Schema Converter

Paste your SQL CREATE TABLE statements into the input editor.

Click 'Convert to Prisma' or choose one of the pre-loaded SQL presets.

Review the generated Prisma schema with mapped scalar types and @relation directives.

Download the schema.prisma file or copy it with one click.

Practical Applications & Scenarios

Daily Professional Workflows

Debugging microservice payload serialization and deserialization errors in real-time.

Quality Assurance & Validation

Verifying cryptographic signatures, token expiries, and access permissions across development and staging environments.

Cross-Device Operational Readiness

Validating database schema migrations and relational constraints prior to production rollouts.

Confidential & Air-Gapped Environments

Ensuring 100% compliance in corporate, regulated, and privacy-sensitive industries where proprietary data cannot touch third-party cloud servers.

Why this tool is important

Rapidly migrate legacy SQL databases to modern Prisma ORM without manual schema authoring.

Automatically maps dialect-specific data types (UUID, SERIAL, TIMESTAMPTZ, JSONB) to Prisma equivalents.

Generates two-way relation fields and back-references on parent and child models automatically.

Best Practices & Tips

•Always double-check input formatting to ensure values strictly adhere to expected units (e.g. metric vs imperial, ISO timestamps, or valid syntax).
•Utilize the 1-click Copy button to transfer clean output directly into your codebase, spreadsheets, or technical documentation.
•Bookmark this page on your desktop browser bar or add it to your mobile home-screen for instant offline-capable access.
•For batch workflows or team collaboration, export the generated outputs or files directly rather than capturing manual screenshots.

Frequently Asked Questions

Which SQL dialects are supported?

PostgreSQL, MySQL, and SQLite DDL syntax are fully supported.

Does it detect foreign key relations?

Yes. Both inline REFERENCES and table-level CONSTRAINT FOREIGN KEY definitions are converted to Prisma @relation fields.

Is SQL to Prisma Schema Converter free to use?

Yes, SQL to Prisma Schema Converter is completely free to use with zero mandatory registration, limits, or intrusive advertisements.

Does this tool work offline?

Yes! Once the page assets load in your browser cache, the entire calculation and generation engine runs client-side, allowing you to use it even with intermittent or absent internet connectivity.

How does Trools ensure calculation accuracy?

All calculations and formatting routines are audited against established industry specifications (RFC 8259 JSON, ISO/IEC Unicode UTF-8, ANSI SQL, and ECMAScript specifications) and verified with automated test suites.
