This is where I lose my mind. This would have been done a long time
ago with RLA with a CHAIN or even MR. But that's the way I think.

Michael,

If strmstpfd has these values

ststr stm#d stm#e
1 a b
2 c
3 d

SELECT * FROM michael/strmstpfd WHERE stm#d <> ' ' and stm#e <> ' '
would only return
ststr stm#d stm#e
1 a b

So if you had 1,2,3 in strmstp it would try to update 2 & 3 with null
values. Normally fixed by some usage of EXISTS to therefore only update 1
and ignore 2 & 3.

Subject: SQL Update Multiple Fields from Different File
Sent by: midrange-l-bounces@xxxxxxxxxxxx



This stuff drives me crazy. With this SQL statement:

UPDATE michael/strmstp a SET (a.stm#d, a.stm#e) =
(select b.stm#d, b.stm#e
from michael/strmstpfd b WHERE a.ststr = b.ststr
and b.stm#d <> ' ' and b.stm#e <> ' ')

I'm getting a Null values not allowed in column or variable STM#D.

I know there is a one to one relationship between the two tables. I
also know that many records in both files

If I do this:

SELECT * FROM michael/strmstpfd WHERE stm#d <> ' ' and stm#e <> ' '

I get all the records I expect, and there are values for each stm#d
and and stm#e.

Any ideas what I'm doing wrong here?

Thanks!
