Today, we are issuing the 5.12.1 patch release to fix two small problems with our new Cloudflare D1 support.

Fixes in Prisma CLI

Windows-only fix for new D1 specific flags for migrate diff and db pull

The flags --from-local-d1 and --to-local-d1 for migrate diff and --local-d1 to db pull we added in 5.12.0 were not working as expected when running on Windows only. This is now fixed.

📚 Documentation: Deploying a Cloudflare worker with D1 and Prisma ORM

New option for migrate diff: -o or --output

We added a new parameter --output to migrate diff that can be used to provide a filename into which the output of the command will be written. This is particularly useful for Windows users, using PowerShell, as using > to write into a file creates a UTF-16 LE file that can not be read by wrangler d1 migrations apply. Using this new option, this problem can be avoided:

npx prisma migrate diff --script --from-empty --to-schema-datamodel ./prisma/schema.prisma --output ./schema.sql

Related issues:

• ✘ [ERROR] near "��": syntax error at offset 0 when running wrangler d1 migrations apply with Prisma generated migration (on Windows, using PowerShell) #23702
• prisma migrate resolve --applied not working on new project, migration ... could not be found.

Today, we are excited to share the 5.12.0 stable release 🎉

Cloudflare D1 (Preview)

This release brings Preview support for Cloudflare D1 with Prisma ORM 🥳

D1 is Cloudflare’s SQLite database that can be used when deploying applications with Cloudflare.

When using Prisma ORM with D1, you can continue to: model your database with Prisma schema language, specify sqlite as your database provider in your Prisma schema, and interact with your database using Prisma Client.

To use Prisma ORM and D1 on Cloudflare Workers or Cloudflare Pages, you need to set sqlite as your database provider and use the @prisma/adapter-d1 database adapter via the driverAdapters Preview feature, released back in version 5.4.0.

Here is an example of sending a query to your D1 database using Prisma Client in your Worker:

// src/index.ts file
import { PrismaClient } from '@prisma/client'
import { PrismaD1 } from '@prisma/adapter-d1'

// Add the D1Database to the Env interface
export interface Env {
// This must match the binding name defined in your wrangler.toml configuration
  DB: D1Database
}

export default {
  async fetch(
    request: Request,
    env: Env,
    ctx: ExecutionContext
  ): Promise<Response> {
    // Make sure the database name matches the binding name in wrangler.toml and Env interface
    const adapter = new PrismaD1(env.DB)
    // Instantiate PrismaClient using the PrismaD1 driver adapter
    const prisma = new PrismaClient({ adapter })

    const users = await prisma.user.findMany()
    const result = JSON.stringify(users)
    return new Response(result)
  },
}

createMany() for SQLite

Bringing support for createMany() in SQLite has been a long-awaited feature ⭐

createMany() is a method on Prisma Client, released back in version 2.16.0, that lets you insert multiple records into your database at once. This can be really useful when seeding your database or inserting bulk data.

Here is an example of using createMany() to create new users:

const users = await prisma.user.createMany({
  data: [
    { name: 'Sonali', email: '[email protected]' },
    { name: 'Alex', email: '[email protected]' },
    { name: 'Yewande', email: '[email protected]' },
    { name: 'Angelina', email: '[email protected]' },
  ],
})

Before this release, if you wanted to perform bulk inserts with SQLite, you would have most likely used $queryRawUnsafe to execute raw SQL queries. But now you don’t have to go through all that trouble 🙂

With SQLite, createMany() works exactly the same way from an API standpoint as it does with other databases except it does not support the skipDuplicates option. At the behavior level, SQLite will split createMany() entries into multiple INSERT queries when the model in your schema contains fields with attributes like @default(dbgenerated()) or @default(autoincrement()) and when the fields are not consistently provided with values across the entries.

📚Documentation: createMany() - Prisma Client API Reference

Fixes and Improvements

Prisma Client

• N+1 Issue with Decimal data type and combining queries (batching)
• Batched findUnique() error out when the field is of Boolean type
• relationJoins MySQL converts nested Decimal to float
• Unexpected query leading to querying full table when using batched findUnique()
• node-postgres (pg) errors with misleading P2010 PrismaClientKnownRequestError when using @prisma/adapter-pg with SSL (?sslmode=require)
• D1 DateTime type does not work

Edge function support for Cloudflare and Vercel (Preview)

We’re thrilled to announce that support for edge function deployments with Prisma ORM is now in Preview 🥳 As of this release, you can deploy your apps that are using Prisma ORM to:

• Vercel Edge Functions and Vercel Edge Middleware
• Cloudflare Workers and Cloudflare Pages

In order to deploy to an edge function, you’ll need to use a compatible database driver (along with its Prisma driver adapter):

• Neon Serverless Driver (for PostgreSQL databases hosted via Neon)
• PlanetScale Serverless Driver (for MySQL databases hosted via PlanetScale)
• pg driver (for traditional PostgreSQL databases)
• @libsql/client driver (for SQLite databases hosted via Turso)

Check out our documentation to learn how you can deploy an edge function using any combination of supported edge function provider and database.

You can also read more about it in the announcement blog post!

Performance improvements in nested create operations

With Prisma ORM, you can create multiple new records in nested queries, for example:

const user = await prisma.user.update({
  where: { id: 9 },
  data: {
    name: 'Elliott',
    posts: {
      create: {
        data: [{ title: 'My first post' }, { title: 'My second post' }],
      },
    },
  },
})

In previous versions, Prisma ORM would translate this into multiple SQL INSERT queries, each requiring its own roundtrip to the database. As of this release, these nested create queries are optimized and the INSERT queries are sent to the database in bulk in a single roundtrip. These optimizations apply to one-to-many as well as many-to-many relations.

With this change, using the nested create option to create multiple records effectively becomes equivalent to using a nested createMany operation (except that createMany only works with one-to-many relations, whereas create works both with one-to-many and many-to-many).

Note: Only the deepest nested operation is optimized. If a user specified create (1) -> create (2) -> create (3) in their query, only create (3) will be optimized.

Optimized relation queries in MySQL (Preview)

This release brings the optimizations for relation queries from the previous releases to MySQL as well! This means that by enabling the relationJoins Preview feature with the mysql database provider, you now also get access to the relationLoadStrategy option in relation queries that let you choose whether you want to merged relations on the application- or database-level.

If you enable the relationJoins Preview feature, you can choose between the join and query options:

• join (default): Sends a single query to the database and joins the data on the database-level.
• query: Sends multiple queries to the database and joins the data on the application-level.

To get started, enable the Preview feature in your Prisma schema:

// schema.prisma
generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["relationJoins"]
}

Be sure to re-generate Prisma Client afterwards:

npx prisma generate

And finally, specify the relation loading strategy for your relation query via the relationLoadStrategy option as follows:

await prisma.user.findMany({
  relationLoadStrategy: 'join', // or 'query' 
  include: {
    posts: true,
  },
})

Note that in the example above, the relationLoadStrategy could be omitted altogether because join is used as the default value.

A few notes about relationLoadStrategy support on MySQL:

• relationLoadStrategy is supported for MySQL v8.0.14 and higher. MariaDB is not supported.
• Prisma ORM uses correlated sub-queries for MySQL (as opposed to LATERAL JOINs which are used on PostgreSQL).

Configure transaction options in the PrismaClient constructor

This feature enables you to configure the following transaction options on a global level via the PrismaClient constructor:

• isolationLevel: Sets the transaction isolation level. By default, this is set to the value currently configured in your database.
• timeout: The maximum amount of time the interactive transaction can run before being canceled and rolled back. The default value is 5 seconds.
• maxWait: The maximum amount of time Prisma Client will wait to acquire a transaction from the database. The default value is 2 seconds.

Here is an example of how you can set this value globally for all transactions:

const prisma = new PrismaClient({
  transactionOptions: {
    isolationLevel: 'ReadCommitted',
    timeout: 1_000, // 1 sec
    maxWait: 2_000  // 2 sec
  }
})

Thanks a lot to our fantastic community member @tockn, who took the initiative to implement this feature in Prisma ORM 🎉

Note that you can still override the global values by setting them on a particular transaction.

New P2037 code for “Too many database connections opened” errors

We introduced a new error code for “Too many database connections opened” errors: P2037. You can find all error codes in our documentation.

Access the Prisma Data Platform via Prisma CLI

Now available in Early Access, you can manage your workspace and configure Prisma Accelerate and Prisma Pulse directly from the terminal.

This release brings a number of small improvements as we continue our work on larger features which you will hear more about in the coming weeks:

• Improve the performance of relation queries by introducing JOINs (see last release).
• Support deployment to edge functions (already available in Early Access, you can apply for trying it out by taking our survey).

Highlights

Optimized result sets for more efficient queries

We continue our efforts of the performance of Prisma Client queries. In 5.1.0, we introduced the RETURNING keyword for several queries on PostrgeSQL and CockroachDB. We now expanded the use of RETURNING to SQLite and a broader range of queries for existing databases (e.g. delete on PostgreSQL and MongoDB). You can learn more about the optimizations of the result sets in these PRs:

• feat(qe): avoid extra select on delete queries
• feat(qe): enable queries with returning for sqlite

SQL Server: Return proper error for unreachable database

When trying migrate/introspect a SQL server instance that’s unreachable, Prisma ORM now returns the correct P1001 error instead of failing without an error. Learn more in this PR: SQL Server: Migrate/Introspection engine doesn't return P1001 error for unreachable url.

Fixes and improvements

Prisma Client

• Skip unnecessary select queries on create/update/delete
• .prisma/client: Name can't start with a dot
• Nested json is transformed to string when used “$type” key in object
• Parallel execution with Promise.all causes P2024 error in version 5.8.0 due to connection limit

Prisma Migrate

• SQL Server: Migrate/Introspection engine doesn't return P1001 error for unreachable url
• Prisma errors fetching table 'CHECK_CONSTRAINTS' (which only exists in MySQL 8.0.16+) in MySQL 8.0.14
• ERROR: column "..." being dropped, try again later when applying migrations with CRDB 23.1

Language tools (e.g. VS Code)

• Extension wrongfully suggests Json as a valid type completion on Sqlite

Test edge functions support in Early Access

Today, the only way how to use Prisma ORM in edge functions (e.g. Cloudflare Workers or Vercel Edge Functions) is by using Prisma Accelerate. However, we are actively working on making Prisma ORM compatible with edge functions natively as well. If you want to become an early tester, you can apply for the private Early Accessing program by taking this survey.

We Transitioned Prisma Accelerate to IPv6 Without Anyone Noticing

Last year, AWS announced the decision to begin charging for IPv4 addresses beginning in February 2024. This move had a major impact on Prisma Accelerate, prompting us to go all-in on IPv6.

Happy New Year from your friends at Prisma! 🎊

In the last 4 weeks, we resolved some bugs on the ORM and made some progress on some exciting features that we’re not yet ready to announce. Stay tuned for the upcoming releases, in which we’ll be announcing new features. 😉

relationJoins improvements: Relation loading strategy per query (Preview)

In version 5.7.0, we released relationJoins into Preview. The relationJoins feature enables support for JOINs for relation queries.

This release adds support for the ability to specify the strategy used to fetch relational data per query when the Preview feature is enabled. This will enable you to choose the most efficient strategy for fetching relation data depending on your use case.

You can now load relation data using either of the following strategies:

• join — uses JOINs to fetch relation data
• query — uses separate queries to fetch relation data

When the relationJoins Preview feature is enabled, by default, the relation fetching strategy used is join. You can override the default behavior by using the relationLoadStrategy query option.

To get started, enable the Preview feature:

// schema.prisma
generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["relationJoins"]
}

… and specify the relation loading strategy for your query as follows:

await prisma.user.findMany({
  relationLoadStrategy: 'query',
  include: {
    posts: true,
  },
})

Try it out and share your feedback and create a bug report if you encounter any issues.

Survey: Edge functions support

We’re working on bringing Edge function support to Prisma ORM and we would appreciate your input by submitting a response to our survey. By filling out the survey, you will be considered for our Early Access cohort as soon as we have something for you to try out.

Fixes and improvements

Prisma Client

• Log output of Node-API library engine is different
• target and timestamp are undefined in info events in Data Proxy client
• Wrong types of timestamp and duration in query events with Data Proxy
• Using citext fields with neon database driver causes conversion error
• Add FreeBSD 14 as a new platform
• PostgresError { code: "54023", message: "cannot pass more than 100 arguments to a function", severity: "ERROR", detail: None, column: None, hint: None }
• Int[] return as null

Prisma Migrate

• Prisma Migrate errors with Environment is non-interactive when VERCEL env var is defined

Language tools (e.g. VS Code)

• Add quickfix for Error validating field 'id' in model 'Post': MongoDB '@default(auto())' fields must have 'ObjectId' native type.
• Append mention of update to "preview feature not known" error message
