Using Prisma Migrate

Creating the database schema

In this guide, you'll use Prisma Migrate to create the tables in your database. Add the following Prisma data model to your Prisma schema in prisma/schema.prisma:

prisma/schema.prisma
1model Post {
2  id        Int      @id @default(autoincrement())
3  createdAt DateTime @default(now())
4  updatedAt DateTime @updatedAt
5  title     String   @db.VarChar(255)
6  content   String?
7  published Boolean  @default(false)
8  author    User     @relation(fields: [authorId], references: [id])
9  authorId  Int
10}
11
12model Profile {
13  id     Int     @id @default(autoincrement())
14  bio    String?
15  user   User    @relation(fields: [userId], references: [id])
16  userId Int     @unique
17}
18
19model User {
20  id      Int      @id @default(autoincrement())
21  email   String   @unique
22  name    String?
23  posts   Post[]
24  profile Profile?
25}

To map your data model to the database schema, you need to use the prisma migrate CLI commands:


$npx prisma migrate dev --name init

This command does two things:

It creates a new SQL migration file for this migration
It runs the SQL migration file against the database

Note: generate is called under the hood by default, after running prisma migrate dev. If the prisma-client-js generator is defined in your schema, this will check if @prisma/client is installed and install it if it's missing.

Great, you now created three tables in your database with Prisma Migrate 🚀

6  content   String?
7  published Boolean  @default(false)
8  author    User     @relation(fields: [authorId], references: [id])
9  authorId  Int
10
11  @@index(authorId)
12}
13
14model Profile {
15  id     Int     @id @default(autoincrement())
16  bio    String?
17  user   User    @relation(fields: [userId], references: [id])
18  userId Int     @unique
19
20  @@index(userId)
21}
22
23model User {
24  id      Int      @id @default(autoincrement())
25  email   String   @unique
26  name    String?
27  posts   Post[]
28  profile Profile?
29}

You are now ready to push your new schema to your database. Connect to your main branch using the instructions in Connect your database.

Now use the db push CLI command to push to the main branch:


$npx prisma db push

In this guide, you'll use Prisma Migrate to create the tables in your database. Add the following Prisma data model to your Prisma schema in prisma/schema.prisma:

prisma/schema.prisma
1model Post {
2  id        BigInt   @id @default(sequence())
3  createdAt DateTime @default(now())
4  updatedAt DateTime @updatedAt
5  title     String   @db.VarChar(255)
6  content   String?
7  published Boolean  @default(false)
8  author    User     @relation(fields: [authorId], references: [id])
9  authorId  BigInt
10}
11
12model Profile {
13  id     BigInt  @id @default(sequence())
14  bio    String?
15  user   User    @relation(fields: [userId], references: [id])
16  userId BigInt  @unique
17}
18
19model User {
20  id      BigInt   @id @default(sequence())
21  email   String   @unique
22  name    String?
23  posts   Post[]
24  profile Profile?
25}

To map your data model to the database schema, you need to use the prisma migrate CLI commands:


$npx prisma migrate dev --name init
