Quick Reference

constructor - PrismaClient setup, adapter wiring, logging, and SQL commenter plugins
model-queries - CRUD operations and bulk operations
query-options - select, include, omit, sort, pagination
filters - scalar and logical filter operators
relations - relation reads and nested writes
transactions - array and interactive transaction patterns
raw-queries - $queryRaw and $executeRaw safety
client-methods - lifecycle methods, extensions, and satisfies patterns for prisma-client

Client Instantiation

import { PrismaClient } from '../generated/client'
import { PrismaPg } from '@prisma/adapter-pg'

const adapter = new PrismaPg({
  connectionString: process.env.DATABASE_URL
})

const prisma = new PrismaClient({ adapter })

Quick Examples

Find records

// Find by unique field
const user = await prisma.user.findUnique({
  where: { email: 'alice@prisma.io' }
})

// Find with filter

  where: { role: 'ADMIN' },
  orderBy: { createdAt: 'desc' },
  take: 10

Create records

const user = await prisma.user.create({
  data: {
    email: 'alice@prisma.io',
    name: 'Alice',
    posts: {
      create: { title: 'Hello World' }
    }
  },
  include: { posts: true }
})

Update records

const user = await prisma.user.update({
  where: { id: 1 },
  data: { name: 'Alice Smith' }
})

Delete records

await prisma.user.delete({
  where: { id: 1 }
})
