Database drivers
Default built-in drivers
One of Prisma Client's components is the Query Engine . The Query Engine is responsible for transforming Prisma Client queries to SQL statements. The Query Engine connects to your database using the included drivers that don't require additional setup. The built-in drivers use TCP connections to connect to the database.
Driver adapters
Prisma Client can connect and run queries against your database using JavaScript database drivers using driver adapters. Adapters act as translators between Prisma Client and the JavaScript database driver.
Prisma will use the Query Engine to transform the Prisma Client query to SQL and run the generated SQL queries via the JavaScript database driver.
There are 2 different types of driver adapters:
Database driver adapters
You can connect to your database using a Node.js-based driver from Prisma Client using a database driver adapter. Prisma maintains the following database driver adapters:
Serverless driver adapters
Database providers, such as Neon and PlanetScale, allow you to connect to your database using other protocols besides TCP, such as HTTP and WebSockets. These database drivers are optimized for connecting to your database in serverless and edge environments.
Prisma maintains the following serverless driver adapters:
Community maintained database driver adapters
You can also build your own driver adapter for the database you're using. The following is a list of community maintained driver adapters:
