Today we are releasing the 6.2.1 patch release to address an issue with some of the omitApi preview feature checks having been accidentally omitted when making the feature GA. Now it is fully functional without the preview feature flag.

Today we're releasing Prisma ORM version 6.2.0 🎉

🌟 Help us spread the word about Prisma by starring the repo or tweeting about the release. 🌟

We have a number of new features in this version, including support for json and enum fields in SQLite, a new updateManyAndReturn function, support for ULID values, as well as the promotion of the omit feature from Preview to Generally Availability.

Highlights

Excluding fields via omit is now production-ready

Our number one requested feature is out of Preview and Generally Available. In 6.2.0, you no longer need to add omitApi to your list of Preview features:

generator client {
  provider        = "prisma-client-js"
- previewFeatures = ["omitApi"]
}

As a refresher: omit allows you to exclude certain fields from being returned in the results of your Prisma Client queries.

You can either do this locally, on a per-query level:

const result = await prisma.user.findMany({
  omit: {
    password: true,
  },
});

Or globally, to ensure a field is excluded from all queries of a certain model:

const prisma = new PrismaClient({
  omit: {
    user: {
      password: true
    }
  }
})

// The password field is excluded in all queries, including this one
const user = await prisma.user.findUnique({ where: { id: 1 } })

For more information on omit, be sure to check our documentation.

json and enum fields in SQLite

Previous to this version, you could not define json and enum fields in your Prisma schema when using SQLite. The respective GitHub issues have been among the most popular ones in our repo, so with our new approach to open-source governance, we finally got to work and implemented these.

Working with JSON and Enum fields works similarly to other database providers, here’s an example:

datasource db {
  provider = "sqlite"
  url      = "file:./dev.db"
}

model User {
  id   Int    @id @default(autoincrement())
  name String
  role Role  
  data Json
}

enum Role {
  Customer
  Admin 
}

Support for auto-generated ULID values

Similar to cuid2 support released in ORM version 6.0.0, we are now adding support for Universally Unique Lexicographically Sortable Identifiers (or short: ULIDs 😄) in version 6.2.0. A ULID value is a 26-character alphanumeric string, e.g. 01GZ0GZ3XARH8ZP44A7TQ2W4ZD.

With this new feature, you can now create records with auto-generated ULID values for String fields:

model User {
  id String @id @default(ulid())  
}

New batch function: updateManyAndReturn

updateMany allows you to update many records in your database, but it only returns the count of the affected rows, not the resulting rows themselves. With updateManyAndReturn you are now able to achieve this:

const users = await prisma.user.updateManyAndReturn({
  where: {
    email: {
      contains: 'prisma.io',
    }
  },
  data: {
    role: 'ADMIN'
  }
})

This call to updateManyAndReturn will now return the actual records that have been updated in the query:

[{
  id: 22,
  name: 'Alice',
  email: 'alice@prisma.io',
  profileViews: 0,
  role: 'ADMIN',
  coinflips: []
}, {
  id: 23,
  name: 'Bob',
  email: 'bob@prisma.io',
  profileViews: 0,
  role: 'ADMIN',
  coinflips: []
}]

Please note that like createManyAndReturn, updateManyAndReturn is only supported in PostgreSQL, CockroachDB, and SQLite.

Fixed runtime error in Node.js v23

While not officially supported, we understand that a lot of you like to be on the latest Node.js version — so we fixed an error that only occurred on Node.js 23. Happy coding ✌️
