Collection query for AD group which has group member

Hi,

I 'm trying to make this query work to get the contents of and AD group visible in an SCCM collection.
For a user collection this works (the group APPV-UNINSTALL pops up in the usercolelction):

select SMS_R_USERGROUP.ResourceID,SMS_R_USERGROUP.ResourceType,SMS_R_USERGROUP.Name,SMS_R_USERGROUP.UniqueUsergroupName,SMS_R_USERGROUP.WindowsNTDomain from SMS_R_UserGroup where SMS_R_UserGroup.UsergroupName = "APPV-UNINSTALL"

For a system collection, I'd like to query the same group but the query doesn't work, just replaced user by system (error in query):

select SMS_R_systemGROUP.ResourceID,SMS_R_systemGROUP.ResourceType,SMS_R_systemGROUP.Name,SMS_R_systemGROUP.UniquesystemgroupName,SMS_R_systemGROUP.WindowsNTDomain from SMS_R_systemGroup where SMS_R_systemGroup.systemgroupName = "APPV-UNINSTALL"

Please advise.
J.
