Windows Management Instrumentation Query Language (WQL) is Microsoft's implementation of the CIM Query Language (CQL), a query language for the Common Information Model (CIM) standard from the Distributed Management Task Force (DMTF). It is a subset of ANSI standard SQL with minor semantic changes.[1]
WQL is dedicated to WMI and is designed to perform queries against the CIM repository to retrieve information or get event notifications.
Example
[edit]As an example, the following WQL query selects all the drives on a computer that have less than 2 MB of free space:[2]
SELECT * FROM Win32_LogicalDisk WHERE FreeSpace < 2097152
