# pull

The `prisma db pull` command connects to your database and adds Prisma models to your Prisma schema that reflect the current database schema.

## [Usage](#usage)

```
prisma db pull [options]
```

The datasource URL configuration is read from the Prisma config file (e.g., `prisma.config.ts`).

:::callout{intent="warning"}
This command will overwrite the current `schema.prisma` file with the new schema. Back up your current schema or commit to version control before running `db pull` if it contains important modifications.
:::

:::callout{intent="note"}
Introspection with `db pull` on the [MongoDB connector](/guides/core-concepts-v7-supported-databases-mongodb) samples the data instead of reading a schema.
:::

## [Prerequisites](#prerequisites)

Configure your database connection in `prisma.config.ts`:

```
generator client {

  provider = "prisma-client"

  output   = "../generated/prisma"

}

datasource db {

  provider = "sqlite"

}
```

```
import { defineConfig, env } from "prisma/config";

export default defineConfig({

  schema: "prisma/schema.prisma",

  migrations: {

    path: "prisma/migrations",

  },

  datasource: {

    url: env("DATABASE_URL"),

  },

});
```
