Querying DB Instances

Function

This API is used to query DB instances based on specified conditions.

URI

URI format
GET /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}

Parameter description

**Table 1** Parameter description
Name	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID of a tenant in a region.
id	No	String	Specifies the DB instance ID.
name	No	String	Specifies the DB instance name. If you use asterisk () at the beginning of the name, fuzzy search results are returned. Otherwise, the exact results are returned. NOTE: The asterisk () is a reserved character in the system and cannot be used alone.
mode	No	String	Specifies the instance type. Sharding indicates the cluster instance. ReplicaSet indicate the replica set instance.
datastore_type	No	String	Specifies the database type. The value is DDS-Community.
vpc_id	No	String	Specifies the VPC ID. You can log in to the VPC console and obtain the ID of the VPC where the DDS instance is located.
subnet_id	No	String	Specifies the network ID of the subnet. You can log in to the VPC console and obtain the network ID of the subnet in the VPC where the DDS instance is located.
offset	No	Integer	Specifies the index position. The query starts from the next instance creation time indexed by this parameter under a specified project. If offset is set to N, the resource query starts from the N+1 piece of data The value must be greater than or equal to 0. If this parameter is not transferred, offset is set to 0 by default, indicating that the query starts from the latest created DB instance.
limit	No	Integer	Specifies the maximum allowed number of DB instances. The value ranges from 1 to 100. If this parameter is not transferred, the first 100 DB instances are queried by default.
