PLSQL Block for Update Statement

Question

Oracle : 10.2.0.5
update TEST.USER_PROFILEs c
set c.uswin = (
select a.uswin from TEST.GBL_USER_PROFILE a, test.user_profiles b
where b.five_and_two=a.uswin
where c.five_and_two in ( select e.uswin from TEST.GBL_USER_PROFILE e, test.user_profiles f
where f.five_and_two=e.uswin )
above query is throwing
ORA-01427: single-row subquery returns more than one row that's because of my in clause.
Looks like I have to write a block to update my user_profile table from GBL_USER_PROFILE. Any suggestiion ??

Answer 1

It is completely unclear what are you trying to do, but looks like:
update  TEST.USER_PROFILEs c
   set  c.uswin = (
                   select  a.uswin
                     from  TEST.GBL_USER_PROFILE a
                     where c.five_and_two=a.uswin
  where c.five_and_two in (
                           select  uswin
                             from  TEST.GBL_USER_PROFILE
/SY.
