Quick Examples
Find records
// Find by unique field
const user = await prisma.user.findUnique({
where: { email: 'alice@prisma.io' }
})
// Find with filter
const users = await prisma.user.findMany({
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 }
})
Transactions
const [user, post] = await prisma.$transaction([
prisma.user.create({ data: { email: 'alice@prisma.io' } }),
prisma.post.create({ data: { title: 'Hello', authorId: 1 } })
