Exclusion of a pc

Hello good to all many thanks for sharing your knowledge.

The issue is that I have installed the SCCM 2007 and I would be able to exclude the pc´s of a collection in all the other collections to be able to add them with "Add resource" manually. I've tried with a Query that excludes the collection, but introducing a pc d that collection by hand let me enter it, I used this sentence:

<<select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ResourceId not in (Select ResourceID from SMS_FullCollectionMembership where CollectionID="IND00160")>>
