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 on the Solaris platform.

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

Table 5-1 Mapping of SQL Concepts to WQL

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.
