The set of object IDs returned is dependant on the difference type category. For example, if the difference type DeleteNoChange is applied, the cursor will be nothing since the row no longer exists. In this case, it is necessary to enumerate until the returned OID equals -1. Use the OID returned in the cursor to retrieve the row in the other version of the table where the row has not been deleted yet.
