## Export D1 Database as SQL

`client.d1.database.export(stringdatabaseId, DatabaseExportParamsparams, RequestOptionsoptions?): DatabaseExportResponse`

**post** `/accounts/{account_id}/d1/database/{database_id}/export`

Returns a URL where the SQL contents of your D1 can be downloaded. Note: this process may take
some time for larger DBs, during which your D1 will be unavailable to serve queries. To avoid
blocking your DB unnecessarily, an in-progress export must be continually polled or will automatically cancel.

### Parameters

- `databaseId: string`

  D1 database identifier (UUID).

- `params: DatabaseExportParams`

  - `account_id: string`

    Path param: Account identifier tag.

  - `output_format: "polling"`

    Body param: Specifies that you will poll this endpoint until the export completes

    - `"polling"`

  - `current_bookmark?: string`

    Body param: To poll an in-progress export, provide the current bookmark (returned by your first polling response)

  - `dump_options?: DumpOptions`

    Body param

    - `no_data?: boolean`

      Export only the table definitions, not their contents

    - `no_schema?: boolean`

      Export only each table's contents, not its definition

    - `tables?: Array<string>`

      Filter the export to just one or more tables. Passing an empty array is the same as not passing anything and means: export all tables.

### Returns

- `DatabaseExportResponse`

  - `at_bookmark?: string`

    The current time-travel bookmark for your D1, used to poll for updates. Will not change for the duration of the export task.

  - `error?: string`

    Only present when status = 'error'. Contains the error message.

  - `messages?: Array<string>`

    Logs since the last time you polled

  - `result?: Result`

    Only present when status = 'complete'

    - `filename?: string`

      The generated SQL filename.

    - `signed_url?: string`

      The URL to download the exported SQL. Available for one hour.

  - `status?: "complete" | "error"`

    - `"complete"`

    - `"error"`

  - `success?: boolean`

  - `type?: "export"`

    - `"export"`

### Example

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const response = await client.d1.database.export('xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx', {
  account_id: '023e105f4ecef8ad9ca31a8372d0c353',
  output_format: 'polling',
});

console.log(response.at_bookmark);
```
