Usage

Upsert

Import the upsert module to extend the query builder API with a upsert method.

[!WARNING] 🐬 MySQL is not supported yet.

The upsert method intelligently infers the correct columns to update based on the primary key and unique constraints of the table. This means you're not required to manually specify a where clause (as you would in Prisma).

// Choose your dialect
import 'drizzle-plus/pg/upsert'
import 'drizzle-plus/sqlite/upsert'

// Now you can use the `upsert` method
const query = db.query.user.upsert({
  data: {
    id: 42,
    name: 'Chewbacca',
  },
})

query.toSQL()
// => {
//   sql: `insert into "user" ("id", "name") values (?, ?) on conflict ("user"."id") do update set "name" = excluded."name" returning "id", "name"`,
//   params: [42, 'Chewbacca'],
// }

// Execute the query
const result = await query
// => {
//   id: 42,
//   name: 'Chewbacca',
// }

Returning clause

By default, upsert will return all columns of the upserted row. But you can specify a returning clause to return only the columns you want. Any SQL expression is allowed in the returning clause.

import { upper } from 'drizzle-plus'

const result = await db.query.user.upsert({
  data: {
    id: 42,
    name: 'Chewbacca',
  },
  // Pass a function to reference the upserted row, or pass a plain object.
  returning: user => ({
    id: true,
    nameUpper: upper(user.name),
    random: sql<number>`random()`,
  }),
})
// => {
//   id: 42,
//   nameUpper: 'CHEWBACCA',
//   random: 0.123456789,
// }

Set returning to an empty object to return nothing.

Upserting many rows

You may pass an array of objects to the data property to upsert many rows at once. For optimal performance and atomicity guarantees, the rows are upserted in a single query.

const rows = await db.query.user.upsert({
  data: [
    { id: 42, name: 'Chewbacca' },
    { id: 43, name: 'Han Solo' },
  ],
})
// => [{ id: 42, name: 'Chewbacca' }, { id: 43, name: 'Han Solo' }]

Conditional updates

If a row should only be updated if it matches a certain condition, you can set the where option. This accepts the same object as the where clause of db.query#findMany().

const query = db.query.user.upsert({
  data: {
    id: 42,
    handle: 'chewie',
  },
  where: {
    emailVerified: true,
  },
})

query.toSQL()
// => {
//   sql: `insert into "user" ("id", "handle") values (?, ?) on conflict ("user"."id") do update set "handle" = excluded."handle" where "user"."email_verified" = true returning "id", "handle"`,
//   params: [42, 'chewie'],
// }

Updating with different data

If the data you wish to insert with is different from the data you wish to update with, try setting the update option. This option can either be a function that receives the table as an argument, or a plain object. This feature works with both single and many upserts (e.g. when data is an array).

const query = db.query.user.upsert({
  data: {
    id: 42,
    loginCount: 0,
  },
  update: user => ({
    // Mutate the existing count if the row already exists.
    loginCount: sql`${user.loginCount} + 1`,
  }),
})

query.toSQL()
// => {
//   sql: `insert into "user" ("id", "login_count") values (?, ?) on conflict ("user"."id") do update set "login_count" = "user"."login_count" + 1 returning "id", "login_count"`,
//   params: [42, 0],
// }

Upserting relations

There are no plans to support Prisma’s connect or connectOrCreate features. It’s recommended to use db.transaction() instead.

[!NOTE] Depending on the complexity of the relations, it may be possible to utilize subqueries instead of using db.transaction(). Do that if you can, since it will avoid the round trip caused by each await in the transaction callback.

import 'drizzle-plus/pg/upsert'
import { nest } from 'drizzle-plus'

await db.transaction(async tx => {
  const { id } = await tx.query.user.upsert({
    data: {
      id: 42,
      name: 'Chewbacca',
    },
    returning: {
      id: true,
    },
  })
  await tx.query.friendship.upsert({
    data: {
      userId: id,
      friendId: nest(
        tx.query.user.findFirst({
          where: {
            name: 'Han Solo',
          },
          columns: {
            id: true,
          },
        })
      ),
    },
  })
})

Update Many

Import the updateMany module to extend the query builder API with a updateMany method.

The updateMany method has the following options:

set: (required) The columns to update. May be a function or a plain object.
where: A filter to only update rows that match the filter. Same API as findMany().
orderBy: The order of the rows to update. Same API as findMany().
limit: The maximum number of rows to update.
returning: The columns to return. Same API as upsert() above.

// Choose your dialect
import 'drizzle-plus/pg/updateMany'
import 'drizzle-plus/mysql/updateMany'
import 'drizzle-plus/sqlite/updateMany'

// Now you can use the `updateMany` method
const query = db.query.user.updateMany({
  // Pass a function to reference the updated row, or pass a plain object.
  set: user => ({
    name: sql`upper(${user.name})`,
  }),
  where: {
    name: 'Jeff',
  },
})

query.toSQL()
// => {
//   sql: `update "user" set "name" = upper("user"."name") where "user"."name" = ?`,
//   params: ['Jeff'],
// }

If the returning option is undefined or an empty object, the query will return the number of rows updated. Otherwise, an array of objects will be returned.

Count

Import the count module to extend the query builder API with a count method.

// Choose your dialect
import 'drizzle-plus/pg/count'
import 'drizzle-plus/mysql/count'
import 'drizzle-plus/sqlite/count'

// Now you can use the `count` method
const count = db.query.foo.count()
//    ^? Promise<number>

// Pass filters to the `count` method
const countWithFilter = db.query.foo.count({
  id: { gt: 100 },
})

// Inspect the SQL:
console.log(countWithFilter.toSQL())
// {
//   sql: `select count(*) from "foo" where "foo"."id" > 100`,
//   params: [],
// }

// Execute the query
const result = await countWithFilter
// => 0

Find Unique

Import the findUnique module to extend the query builder API with a findUnique method.

The only thing findUnique() does differently from findFirst() is that it requires the where clause to match a primary key or unique constraint. Unfortunately, Drizzle doesn't have type-level tracking of primary keys or unique constraints, so findUnique() will only throw at runtime (no compile-time warnings).

// Choose your dialect
import 'drizzle-plus/pg/findUnique'
import 'drizzle-plus/mysql/findUnique'
import 'drizzle-plus/sqlite/findUnique'

// Now you can use the `findUnique` method
const result = await db.query.user.findUnique({
  where: {
    id: 42,
  },
})
// => { id: 42, name: 'Chewbacca' }

If no matching record is found, findUnique() will resolve to undefined.

Find Many and Count

Import the findManyAndCount module to extend the query builder API with a findManyAndCount method.

The findManyAndCount method accepts the same arguments as findMany(), and returns an object with data and count properties. The count is the total number of rows that would be returned by the findMany query, without any limit or offset applied.

// Choose your dialect
import 'drizzle-plus/pg/findManyAndCount'
import 'drizzle-plus/mysql/findManyAndCount'
import 'drizzle-plus/sqlite/findManyAndCount'

// Now you can use the `findManyAndCount` method
const { data, count } = await db.query.foo.findManyAndCount({
  where: {
    age: { gt: 20 },
  },
  limit: 2,
  columns: {
    id: true,
    name: true,
    age: true,
  },
})
// => {
//   data: [
//     { id: 1, name: 'Alice', age: 25 },
//     { id: 2, name: 'Bob', age: 30 },
//   ],
//   count: 10,
// }

The two queries (findMany and count) are executed in parallel.

[!WARNING] Your database connection may not support parallel queries, in which case this method will execute the queries sequentially.

Cursor-Based Pagination

Import the $cursor module to extend the query builder API with a $cursor method.

With $cursor(), you get the peace of mind knowing that TypeScript will catch any errors in your cursor-based pagination. No more forgotten orderBy clauses, mismatched cursor objects, or manually-written where clauses.

Just give it your desired sort order and the cursor object, and it will generate the correct where clause.

// Step 1: Choose your dialect
import 'drizzle-plus/pg/$cursor'
import 'drizzle-plus/mysql/$cursor'
import 'drizzle-plus/sqlite/$cursor'

// Step 2: Use the `$cursor` method
const cursorParams = db.query.foo.$cursor({ id: 'asc' }, { id: 99 })
// => {
//   where: { id: { gt: 99 } },
//   orderBy: { id: 'asc' },
// }

// Step 3: Add the cursor parameters to your query
const results = await db.query.foo.findMany({
  ...cursorParams,
  columns: {
    id: true,
    name: true,
    age: true,
  },
})

Arguments:
- The first argument is the “order by” clause. This is used to determine the comparison operator for each column, and it's returned with the generated where filter. Property order is important.
- The second argument is the user-provided cursor object. It can be null or undefined to indicate the start of the query.
Returns: The query parameters that you should include in your query. You can spread them into the options passed to findMany(), findFirst(), etc.

Cursors with multiple columns

In addition to type safety and auto-completion, another nice thing about $cursor() is its support for multiple columns.

const cursorParams = db.query.user.$cursor(
  { name: 'asc', age: 'desc' },
  { name: 'John', age: 20 }
)

cursorParams.where
// => { name: { gte: 'John' }, age: { lt: 20 } }

cursorParams.orderBy
// => { name: 'asc', age: 'desc' }

[!NOTE] The order of keys in the first argument to $cursor() is important, as it helps in determining the comparison operator for each column. All except the last key allow rows with equal values (gte or lte), while the last key is always either gt (for ascending order) or lt (for descending order).

Also of note, as of June 28 2025, Drizzle doesn't yet provide control over treatment of NULL values when using the Relational Query Builder (RQB) API. While this library could implement it ourselves (at least, for the $cursor method), we'd prefer to wait for Drizzle to provide a proper solution.

Materialized CTEs

Import the $withMaterialized module to extend the query builder API with $withMaterialized() and $withNotMaterialized() methods.

These methods add MATERIALIZED and NOT MATERIALIZED keywords to the CTEs, respectively, just after the AS keyword. You can learn more about materialized CTEs in the PostgreSQL docs.

[!WARNING] This feature is only available in Postgres.

import 'drizzle-plus/pg/$withMaterialized'

// Same API as db.$with()
const cte1 = db.$withMaterialized(alias).as(subquery)
const cte2 = db.$withNotMaterialized(alias).as(subquery)

Universal SQL functions

These functions are available in all dialects, since they're part of the SQL standard.

Syntax:
- caseWhen
- nest
- toSQL
SQL functions:
- abs
- ceil
- coalesce
- concatWithSeparator
- currentDate
- currentTime
- currentTimestamp
- floor
- length
- lower
- mod
- nullif
- power
- round
- sqrt
- substring
- trim
- upper

Import them from the drizzle-plus module:

import { caseWhen } from 'drizzle-plus'

Timestamps

Any drizzle-plus function that returns a timestamp will return a SQLTimestamp object, which extends the SQL class. Call the toDate() method to instruct Drizzle to parse it into a Date object (which is only relevant if the timestamp is used in a select or returning clause).

import { currentTimestamp } from 'drizzle-plus'

const now = currentTimestamp()
// => SQLTimestamp<string>

now.toDate()
// => SQL<Date>

Dialect-specific SQL functions

These functions have differences between dialects, whether it's the name, the function signature, or its TypeScript definition relies on dialect-specific types.

Postgres:
- concat
- jsonAgg
- jsonBuildObject
- position
- uuidv7
- uuidExtractTimestamp
MySQL:
- concat
- jsonArrayAgg
- jsonObject
- position
SQLite:
- concat
- instr
- jsonGroupArray
- jsonObject

// Postgres imports
import { jsonAgg } from 'drizzle-plus/pg'

// MySQL imports
import { jsonArrayAgg } from 'drizzle-plus/mysql'

// SQLite imports
import { jsonGroupArray } from 'drizzle-plus/sqlite'

Utility functions

The drizzle-plus package also has some functions that don't produce SQL expressions, but exist for various use cases.

mergeFindManyArgs Combines two configs for a findMany query.
mergeRelationsFilter Combines two where filters for the same table.

import { mergeFindManyArgs, mergeRelationsFilter } from 'drizzle-plus'

Type-safe query definitions

Import the $findMany module to extend the query builder API with a $findMany method.

The $findMany() method is used to define a query config for a findMany query in a type-safe way. If you pass two configs, it will merge them. This is useful for Query Composition™, which is a technique for building complex queries by composing simpler ones.

[!NOTE] This method does not execute the query. It only returns a query config.

// Choose your dialect
import 'drizzle-plus/pg/$findMany'
import 'drizzle-plus/mysql/$findMany'
import 'drizzle-plus/sqlite/$findMany'

// Now you can use the `$findMany` method
const query = db.query.foo.$findMany({
  columns: {
    id: true,
  },
})

// The result is strongly-typed!
query.columns
//    ^? { readonly id: true }

// You can also pass two configs to merge them
const query2 = db.query.foo.$findMany(
  {
    columns: {
      id: true,
    },
  },
  {
    columns: {
      name: true,
    },
  }
)
// => {
//   columns: {
//     id: true,
//     name: true,
//   },
// }

When you pass two configs to $findMany(), it passes them to mergeFindManyArgs() and returns the result. Here's how the merging actually works:

The columns, with, and extras properties are merged one level deep.
The where property is merged using mergeRelationsFilter().
Remaining properties are merged via spread syntax (e.g. orderBy is replaced, not merged).

Types

Here are some useful types that drizzle-plus provides:

// Universal types
import {
  InferWhereFilter,
  InferFindManyArgs,
  InferFindFirstArgs,
} from 'drizzle-plus/types'

// Pass the query builder to the type
type WhereFilter = InferWhereFilter<typeof db.query.foo>
type FindManyArgs = InferFindManyArgs<typeof db.query.foo>
type FindFirstArgs = InferFindFirstArgs<typeof db.query.foo>
