createManyAndReturn()

We’re happy to announce the availability of a new, top-level Prisma Client query: createManyAndReturn(). It works similarly to createMany() but uses a RETURNING clause in the SQL query to retrieve the records that were just created.

Here’s an example of creating multiple posts and then immediately returning those posts.

const postBodies = req.json()['posts']

const posts = prisma.post.createManyAndReturn({
  data: postBodies
});

return posts

Additionally,createManyAndReturn() supports the same options as findMany(), such as the ability to return only specific fields.

const postBodies = req.json()['posts']

const postTitles = prisma.post.createManyAndReturn({
  data: postBodies,
  select: {
    title: true,
  },
});

return postTitles

Full documentation for this feature can be found in the Prisma Client API Reference.

Note: Because createManyAndReturn() uses the RETURNING clause, it is only supported by PostgreSQL, CockroachDB, and SQLite databases. At this time, relationLoadStrategy: join is not supported in createManyAndReturn() queries.

MongoDB performance improvements

Previously, Prisma ORM suffered from performance issues when using the in operator or when including related models in queries against a MongoDB database. These queries were translated by the Prisma query engine in such a way that indexes were skipped and collection scans were used, leading to slower queries especially on large datasets.

With 5.14.0, Prisma ORM now rewrites queries to use a combination of $or and $eq operators, leading to dramatic performance increases for queries that include in operators or relation loading.

Fixes and improvements

Prisma Client

• createMany() should return the created records
• Generating Prisma client without any model in its schema
• MongoDB: Performance issue with nested take on many-to-one relationship
• Slow queries on MongoDB using include for relations
• [MongoDB] Performance issue in findMany() query execution with in
• MongoDB nested/include query slow
• MongoDB Connector generates queries which do not take advantage of indices.
• Mongodb Nested Queries Not Using Indexes
• MongoDB slow delete with onDelete: SetNull
• Slow query with many-to-one relationship on MongoDB
• prisma init --with-model
• Fixed version of @opentelemetry/* dependencies
• Usage of deprecated punycode module
• Bug: D1 One-to-Many Relation INSERTs fail with The required connected records were not found. when using indices

Prisma Migrate

• Empty dbgenerated() still breaking for Unsupported() types
• Validation error when shadowDatabaseUrl is identical to url (or directUrl)
• MongoDB Query with 'in' condition will cause COLLSCAN, without leveraging indexes
• "Not Authorised" when directly applying Prisma generated migrations to Cloudflare D1 with PRAGMA foreign_key_check;

Language tools (e.g. VS Code)

• make superior: model generate
• Missing code autocomplete for referential actions with mongodb
