CURSOR c
IS
  SELECT COMPANYID,
         GROUPID,
         PERIODID,
         FN_PPROCESSCURRENT
FROM LIQUIDATIONSDETAILS
   WHERE     PROCESSID = FN_PPROCESSPREVIOUS
         AND (UNCOLLECTED > 0 OR INVOICE = 0)
         AND (((GROUPID = vgroupid) AND (vgroupid > -1)) OR (vgroupid = -1))

na przykład:jeśli vgroupid = -1 , wtedy ostatnim warunkiem będzie (((GROUPID = -1) AND (-1 > -1)) OR (-1 = -1)) lub ((forever_false AND forever_false) OR (forever_true)) lub (-1 = -1) - wszystkie rekordy

zamiast tego, jeśli vgroupid = 123 ostatnim warunkiem będzie (((GROUPID = 123) AND (123 > -1)) OR (123 = -1)) lub (((GROUPID = 123) and forever_true) OR (forever_false)) lub (GROUPID = 123) - tylko 123 GROUPID
