RE: NOT allowing null value into PF fields(big puzzle)

["Joseph Pascoguin" <joe.pascoguin@xxxxxxxxxxx>]

update file a set optcod=
 (select MIN(B.noptcod)
  from xlfile b
  where a.optcod=b.ioptcod)
where exists
 (select 1
  from xlfile b
  where a.optcod=b.ioptcod)

Great! Thanks for the response.
As per your advise I have done the above sql, it has updated 252 rows when 
actually it has to update 297 rows..
In order to update correctly in all rows do you have any further advise 
without getting the problmes (as discussed in below posts)..

I appreciate your help!




Warm Regards,
JoeP
