What he's asking for is not the SQL Standard Syntax!
The SQL Standard Sytax is:
Update Table a
Set UpdFld = (Select Fld
From Table2 b
Where a.Key1 = b.Key1
and a.Key2 = b.Key2 ?
and a.KeyN = b.KeyN)
Where Exists (Select Fld
from Table2 c
Where a.Key1 = c.Key1
and a.Key2 = c.Key2 ?
and a.KeyN = c.KeyN)

Subject: 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
