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

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.

I appreciate your help!

Try:

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

Notice I used MIN to select lowest value for 'noptcod'.  You can use MAX if

you prefer. Bottom line is, you need to ensure your SELECT only selects one record per 'optcod'. With your initial statement, you were getting multiple

matches on the primary dial (optcod).

CREATE TABLE XFILE
(IFUTCOD CHAR (4 ),
  NOPTCOD CHAR (6 ) NOT NULL,
  IOPTCOD CHAR (6 ) NOT NULL WITH DEFAULT)
RCDFMT XFILER

Hi Rob As you said I created the table as above  and
1)I have done CPYFRMIMPF
===> CPYFRMIMPF FROMSTMF('/etc/dalc/apps/testfile1.csv') TOFILE(JPASCO/
XFILE) MBROPT(*REPLACE) RCDDLM(*CRLF)

and tried to execute the simple SQL:

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

The sql displays line "      Null values not allowed in column or variable
optcod"

---as per Birgitta's advise I tried to execute the below sql, but i get same

problem
update FILE a
       set OPTCOD = (select b.nOPTCOD from XLFILE b where
a.OPTCOD=b.iOPTCOD)
       where exists (select c.iOPTCOD from XLFILE C where
a.OPTCOD=c.iOPTCOD)

I end up with an error which as below:
"Result of SELECT more than one row."

I have introduced distinct in select statement above , but still same
problem...
Do you think any solution for this?


Warm Regards,
