InfluxQL requires a database and retention policy (DBRP) combination in order to query data.
In {{< product-name >}}, databases and retention policies are
combined and replaced by InfluxDB [buckets](/influxdb/cloud-serverless/reference/glossary/#bucket).
To query an {{< product-name >}} bucket with InfluxQL, first map each DBRP
combination to a bucket.

- [List DBRP mappings](#list-dbrp-mappings)
- [Update a DBRP mapping](#update-a-dbrp-mapping)
- [Delete a DBRP mapping](#delete-a-dbrp-mapping)

## Automatic DBRP mapping

{{< product-name >}} automatically creates DBRP mappings for you during the
following operations:

- Writing to the [`/write` v1 compatibility endpoint](/influxdb/cloud-serverless/guides/api-compatibility/v1/#write-data)
- [Upgrading from InfluxDB 1.x to InfluxDB Cloud](/influxdb/v2/upgrade/v1-to-cloud/)

For more information, see [Database and retention policy mapping](/influxdb/cloud-serverless/api/#tag/DBRPs).

## Create DBRP mappings

Use the [`influx` CLI](/influxdb/cloud-serverless/reference/cli/influx/) or the
[InfluxDB API](/influxdb/cloud-serverless/reference/api/) to create DBRP mappings.

{{% note %}}
#### A DBRP combination can only be mapped to a single bucket
Each unique DBRP combination can only be mapped to a single bucket.
If you map a DBRP combination that is already mapped to another bucket,
it will overwrite the existing DBRP mapping.

Use the [`influx v1 dbrp create` command](/influxdb/cloud-serverless/reference/cli/influx/v1/dbrp/create/)
to map a database and retention policy to a bucket.
Include the following:

{{< req type="key" >}}

- {{< req "\*" >}} **API token** to authenticate. We recommend setting your token to
  your active InfluxDB connection configuration in the `influx` CLI, so you don't
  have to add these parameters to each command.
  To set up your active InfluxDB configuration, see
  [`influx config set`](/influxdb/cloud-serverless/reference/cli/influx/config/set/).
- {{< req "\*" >}} **database name** to map
- {{< req "\*" >}} **retention policy** name to map
- {{< req "\*" >}} [Bucket ID](/influxdb/cloud-serverless/admin/buckets/view-buckets/#view-buckets-in-the-influxdb-ui) to map to
- **Default flag** to set the provided retention policy as the default retention policy for the database

## List DBRP mappings

Use the [`influx` CLI](/influxdb/cloud-serverless/reference/cli/influx/) or the
[InfluxDB HTTP API](/influxdb/cloud-serverless/reference/api/) to list all DBRP
mappings and verify the buckets you want to query are mapped to a database and
retention policy.
