Complex wmi queries using execquery

In powershell I can do a query like

> get-wmiobject -query 'select * from win32_groupuser' | % {[wmi]$_.partcomponent|select domain,name,SID}

Which will list for each wmi, the domain, name and sid for each user.

How would I accomplish this using vbscript?

I currently use execquery:

objWMIService.ExecQuery("select partcomponent,groupcomponent from win32_groupuser")

for the first part, but how do I incorporate the equivalent of | % {[wmi]$_.partcomponent|select domain,name,SID}

Alteatively, how could I do

gwmi win32_groupuser | % { [wmi]$_.partcomponent }

using vbscript; as it is not a query, I caot use execquery, but it does the same thing
