Model Queries

CRUD operations for your Prisma models.

const user = await prisma.user.findUnique({
  where: { id: 1 }
})

const user = await prisma.user.findUnique({
  where: { email: 'alice@prisma.io' }
})

With composite unique key

// Model with @@unique([firstName, lastName])
const user = await prisma.user.findUnique({
  where: {
    firstName_lastName: {
      firstName: 'Alice',
      lastName: 'Smith'
    }
  }
})

const user = await prisma.user.findUniqueOrThrow({
  where: { id: 1 }
})
// Throws PrismaClientKnownRequestError if not found

findFirst

Find first matching record:

const user = await prisma.user.findFirst({
  where: { role: 'ADMIN' },
  orderBy: { createdAt: 'desc' }
})

findFirstOrThrow

const user = await prisma.user.findFirstOrThrow({
  where: { role: 'ADMIN' }
})

findMany

Find multiple records:

const users = await prisma.user.findMany({
  where: { role: 'USER' },
  orderBy: { name: 'asc' },
  take: 10,
  skip: 0
})
