How to Perform a Synchronous Configuration Manager Query by Using WMI

In Configuration Manager, you perform a synchronous query for Configuration Manager objects by calling the SWbemServices object ExecQuery method and passing a WQL query.

A synchronous query is a query that maintains control over the process of your application for the duration of the query. A synchronous query has the potential of locking up your application for large queries or for queries over a network. Alternatively, you can run an asynchronous query that returns control to the application while the query is run. For more information, see How to Perform an Asynchronous Configuration Manager Query by Using Managed Code

Note

Lazy properties are not returned in synchronous queries. For more information, see How to Read Lazy Properties by Using WMI.

To perform a synchronous query

Set up a connection to the SMS Provider. For more information, see How to Connect to an SMS Provider in Configuration Manager by Using WMI.
Using the SWbemServices object that you obtain from step one, use the ExecQuery method to get a SWbemObjectSet collection containing the query results.
Iterate through the SWbemObjectSet collection to access a SWbemObject for each object returned by the query.

Example

The following example performs a synchronous query of all packages in Configuration Manager.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub QueryPackages(connection)  

    On Error Resume next  

    Dim packages  
    Dim package  

    ' Run the query.  
    Set packages = _  
        connection.ExecQuery("Select * From SMS_Package")  

    If Err.Number<>0 Then  
        Wscript.Echo "Couldn't get Packages"  
        Wscript.Quit  
    End If  

    For Each package In packages  
        WScript.Echo  package.Name  
    Next  

    If packages.Count=0 Then  
        Wscript.Echo "No packages found"  
    End If  

End Sub

This example method has the following parameters:

Parameter	Type	Description
`connection`	SWbemServices	A valid connection to the SMS Provider.
