Overview

ResourceQL provides SQL-like functions, allowing you to flexibly query your cloud resources.

SELECT name, created, updated FROM resources WHERE region_id = 'regionid1'

The statement is case insensitive. SELECT COUNT(*) and select CoUnT(*) are the same. Use single quotation marks to represent the literal of a string.

The following table lists seven data types supported by ResourceQL. For the array type, [] is used to index a position, and the number starts from 1.

**Table 1** Supported data types
Type Name	Type
Integer	Int/Integer
Float	Float/Double
Boolean	Boolean
Array	Array
String	String
Dictionary	Object
Timestamp	Date

All your cloud resources are included in a table. The table name is fixed to resources. The resources under your aggregator account forms a table. The table name is fixed to aggregator_resources. Each row in the table records a piece of data. The conventions of each column are as follows.

**Table 2** Parameter descriptions in table **resources**
Parameter	Type	Description
id	String	Specifies the resource ID.
name	String	Specifies the resource name.
provider	String	Specifies the cloud service name.
type	String	Specifies the resource type.
region_id	String	Specifies the region ID.
project_id	String	Specifies the project ID.
ep_id	String	Specifies the enterprise project ID.
checksum	String	Specifies the resource checksum.
created	Date	Specifies the time when the resource was created.
updated	Date	Specifies the time when the resource was updated.
provisioning_state	String	Specifies the result of an operation on resources.
tag	Array(Map<String,String>)	Specifies the resource tag.
properties	Map<String,Object>	Specifies the resource attribute details.

aggregator_resources contains domain_id that indicates the account ID. The type of a domain ID is a string.

provider and type represent a unique resource. For different resources, properties varies. For example, for an ECS, the provider and type are ecs and cloudservers, and the properties contains flavor. For a VPC, the provider and type are vpc and publicips, and the properties contains bandwidth.

You can obtain resource attributes that can be included in the properties element for each resource on Config console or by calling the related API. For more details, see How Can I Obtain Resource Attributes Reported to Config?

properties supports nested queries. The following shows an example of how to query the addresses parameter under properties for the running ECS.

SELECT name, created, updated, properties.addresses FROM resources 
	WHERE provider = 'ecs' AND type = 'cloudservers' AND properties.status = 'ACTIVE'
