   I haven't tried this, but it should work:   
      
   WHENEVER SQLERROR EXIT FAILURE   
      
   DECLARE   
        recs number := 0;   
   BEGIN   
        SELECT COUNT(*) INTO recs FROM WarehouseTable WHERE ROWNUM=1;   
        IF recs = 0 THEN   
   	RAISE_APPLICATION_ERROR(-20001,'Table empty');   
        END IF;   
   END;
