Hi Vern
What happens if in fileA, there is one record with key with a value of 1 (lets keep it simple)
But in fileB - there are more that one record with key with a value of 1
You may have been lucky in that the time it worked for you there was a 1 to 1 relationship from fileA to fileB

Subject: [EXTERNAL] Re: RFE for SQL update from
Can't we do something like this already?
update fileA
set fileA.field1 = (select field1
from fileB wherekey = fileA.key)
I could be wrong, but I feel like I've done this. Please correct me it it's not doable.
And how is the RFE request different from that?
Cheers
Vern

update fileA
set fileA.field1 = fileB.field1
from fileA inner join fileB on fileB.key = fileA.key
May I have your votes please.
Thanks
