Bulk updates

Update multiple rows through the relational query builder, with filters, ordering, limits, and typed returned rows where the dialect supports them.

Enable it

import 'drizzle-plus/pg/updateMany'
// or 'drizzle-plus/mysql/updateMany'
// or 'drizzle-plus/sqlite/updateMany'

Update matching rows

set is required. where uses the same relation-aware filter shape as findMany():

const updated = await db.query.user.updateMany({
  set: {
    active: true,
  },
  where: {
    lastSeenAt: { isNotNull: true },
  },
})
// updated: number

Use a callback when the new value references the row being updated:

import { sql } from 'drizzle-orm'

await db.query.user.updateMany({
  set: user => ({
    loginCount: sql`${user.loginCount} + 1`,
  }),
  where: { active: true },
})

Limit which rows are updated

limit caps the number of rows, and orderBy decides which rows are selected when the limit is smaller than the match set:

await db.query.user.updateMany({
  set: { active: false },
  where: { lastSeenAt: { isNull: true } },
  orderBy: { id: 'asc' },
  limit: 100,
})

Without orderBy, the database may choose any matching rows.

Return updated rows

On PostgreSQL and SQLite, use returning to receive an array of selected fields instead of a count:

const users = await db.query.user.updateMany({
  set: { active: false },
  where: { lastSeenAt: { isNull: true } },
  returning: {
    id: true,
    active: true,
  },
})
// users: { id: number; active: boolean }[]

returning can be a function, and SQL expressions are allowed in the result. Leave it undefined or pass {} to receive the number of updated rows.
