Querying the DB Instance List
Updated on 2022-09-16 GMT+08:00
Scenarios
This section describes how to call the API described in Querying Instances and Details to query all DDS DB instances of a tenant using pagination parameters.
Procedure
- Configure parameters limit and offset.
- API information
URI format: GET https://{Endpoint}/v3/{project_id}/instances?id={id}&name={name}&mode={mode}&datastore_type={datastore_type}&vpc_id={vpc_id}&subnet_id={subnet_id}&offset={offset}&limit={limit}
- Obtain {endpoint} from Regions and Endpoints.
- {limit} can be adjusted based on the DDS DB instance data.
- For details, see Querying Instances and Details.
- Example request

- API information
- Collect query results.
- Repeat 1 until the returned query result is empty or the returned body does not contain the instances field. This indicates that all DDS instances have been queried.
- Collect all of the queried DDS instances.
