This works:

SELECT Saved_Searches.* ;
  FROM mmviscollect!saved_searches ;
 WHERE Saved_searches.cusgrlink_fk == ( ?vp_cusgrlink_fk );
 OR (Saved_searches.cusgrlink_fk == ( ?vp_vcam_fk ) ;
    AND NOT EXISTS(SELECT * FROM mmviscollect!saved_searches ;
                   WHERE Saved_searches.cusgrlink_fk == ( ?vp_cusgrlink_fk )));
  ORDER BY Saved_searches.isequence_number

Your first query produced an error message "QUERY of this sort is not supported" (I'm running 8.0)

>>Now, in its current way it will always return all records, because we defined all of them for VCAM user. I want it to return "my" records if it finds that cUsgrLink_fk matches my cUsgrLink_fk. However, if I don't have records for my ID, I want it to return all records. Could you please help me a little bit?
