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))

till exempel:if vgroupid = -1 , då kommer det sista villkoret att vara (((GROUPID = -1) AND (-1 > -1)) OR (-1 = -1)) eller ((forever_false AND forever_false) OR (forever_true)) eller (-1 = -1) - alla poster

istället om vgroupid = 123 sista villkoret är (((GROUPID = 123) AND (123 > -1)) OR (123 = -1)) eller (((GROUPID = 123) and forever_true) OR (forever_false)) eller (GROUPID = 123) - endast 123 GROUPID
