# Import from MySQL

Move an existing MySQL database into Prisma Postgres, then connect Prisma ORM to it.

## [Prerequisites](#prerequisites)

You need:

- the connection URL for the MySQL database you are importing from
- a Prisma Data Platform account
- `pgloader`
- Node.js 24 or newer

## [1. Create a Prisma Postgres database](#1-create-a-prisma-postgres-database)

Create a Prisma Postgres database from Console or with the CLI. Copy the direct connection string. You will use it for the import and for `DATABASE_URL`.

## [2. Create a pgloader config](#2-create-a-pgloader-config)

Create `config.load`:

```title="config.load"
LOAD DATABASE

    FROM mysql://USER:PASSWORD@HOST:PORT/DATABASE

    INTO postgres://USER:PASSWORD@db.prisma.io:5432/?sslmode=require

WITH quote identifiers,

     include drop,

     create tables,

     create indexes,

     reset sequences

ALTER SCHEMA 'DATABASE' RENAME TO 'public';
```

## [3. Import into Prisma Postgres](#3-import-into-prisma-postgres)

Run pgloader:

```
pgloader config.load
```

## [4. Add Prisma ORM](#4-add-prisma-orm)

From your app root, initialize Prisma ORM:

:::code-group
```title="bun"
bunx prisma@latest orm init
```

```bash title="pnpm"
pnpm dlx prisma@latest orm init
```

```bash title="yarn"
yarn dlx prisma@latest orm init
```

```bash title="npm"
npx prisma@latest orm init
```
:::

Choose PostgreSQL, set `DATABASE_URL` to the Prisma Postgres connection string, then infer and emit the contract:

:::code-group
```title="bun"
bunx prisma contract infer --output ./prisma/contract.prisma

bunx prisma contract emit

bunx prisma db sign
```

```bash title="pnpm"
pnpm prisma contract infer --output ./prisma/contract.prisma
pnpm prisma contract emit
pnpm prisma db sign
```

```bash title="yarn"
yarn prisma contract infer --output ./prisma/contract.prisma
yarn prisma contract emit
yarn prisma db sign
```

```bash title="npm"
npx prisma contract infer --output ./prisma/contract.prisma
npx prisma contract emit
npx prisma db sign
```
:::

## [Next steps](#next-steps)

- Review table and column names in the inferred contract.
- Use the [PostgreSQL existing-project guide](/guides/prisma-orm-2-prisma-orm-add-to-existing-project-postgresql) for the first Prisma ORM query.
- Use the [full Prisma Postgres MySQL import guide](/guides/prisma-postgres-import-from-existing-database-mysql) for deeper migration details.
