About the WBEM Query Language

The WBEM Query Language (WQL) is a subset of the standard American National Standards Institute Structured Query Language (ANSI SQL). WQL has semantic changes to support WBEM in the Solaris environment.

The following table shows the mapping of SQL concepts to WQL.

Table 5–1 Mapping of SQL Concepts to WQL

SQL Concept 

WQL Representation 


CIM class 


CIM instance 


CIM property 

Note –

Like SQL, WQL statements use single (` ') quotation marks.

In the implementation of Solaris WBEM Services, WQL is a retrieval-only language. You can use WQL to query data that is stored using the CIM data model. In the CIM model, information about objects is stored in CIM classes and CIM instances. CIM instances can contain properties, which have a name, data type, and value.
