SQL to TypeScript / Prisma / Drizzle
Converts SQL CREATE TABLE statements to TypeScript interfaces, Prisma schemas, and Drizzle definitions.
What SQL to TypeScript / Prisma / Drizzle does
This tool converts raw SQL CREATE TABLE statements into TypeScript interfaces, Prisma schemas, and Drizzle ORM definitions. Users paste their SQL, and the service outputs ready-to-use code structures that streamline integrating database schemas into TypeScript backend projects. It handles standard column definitions, constraints like PRIMARY KEY and FOREIGN KEY, and maps over 30 SQL data types to their TypeScript equivalents. What sets this particular site apart is that the entire conversion process runs locally in the user's browser. No data is sent to a server, ensuring privacy for sensitive schema definitions. The interface provides clear side-by-side output panels for each format, a dropdown to select SQL dialects (PostgreSQL, MySQL, SQLite), and a detailed SQL Type Mapping Reference table that shows exact conversions for types like INT, VARCHAR, and TIMESTAMP. Users can also choose to make certain fields optional by appending a question mark to the output.

Best for
Developers who need to quickly generate TypeScript types from an existing SQL database schema without leaving their browser or exposing their data to external servers.
Limitations
- Results are estimates and may require manual adjustments for complex schemas
- No explicit unit switching or advanced type customization options listed
- Output format is fixed per selection; mixed outputs for a single table are not supported
SQL to TypeScript / Prisma / Drizzle FAQ
- Can I convert SQL from any database system?
- The tool supports PostgreSQL, MySQL, and SQLite syntax. It parses standard CREATE TABLE statements including quoted identifiers and common constraints, but may not handle proprietary extensions from other database systems.
- Is my SQL data sent to a server when I use this tool?
- No, all processing happens entirely in your browser. Your SQL input and generated outputs never leave your device, which helps keep sensitive schema definitions private.
- What if my SQL includes foreign keys or unique constraints?
- The tool parses PRIMARY KEY, FOREIGN KEY, and UNIQUE constraints from the input and incorporates them into the generated TypeScript interfaces, Prisma schemas, and Drizzle ORM definitions where applicable.
- Can I customize how the generated types look?
- Users can choose to make fields optional by using the 'Export keyword' feature, which replaces the type with a nullable version (?) instead of null. The SQL Type Mapping Reference also allows selecting specific type conversions for each output format.
