RE: SQL

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

I'd try using the EXISTS predicate. Something like:

UPDATE OEP20E A
  SET OORD20=100, BORD20=0
WHERE
  EXISTS (SELECT * FROM SLP05
          WHERE
             B.CONO05=A.CONO20 AND
             B.CUSN05=A.CUSN20 AND
             B.DSEQ05=A.DSEQ20 AND
             B.CGP105=8)

I use Joe Celko's "SQL for Smarties" as a general reference.  There are
probably better books available, but I don't know them.  Anyway, HTH.

We have 2 files, a customer details file (fields ending in 05) and a
customer attributes files (fields ending in 20). (To readers using JBA,
I'm using SLP05 and OEP20E.)
The join between the customers will be fields called CONO05/20, CUSN05/20
and DSEQ05/20
I would like an SQL statement to the effect of
UPDATE OEP20E SET OORD20=100 BORD20=0
WHERE CGP105 =008
CONO05=CONO20
CUSN05=CUSN20
DSEQ05=DSEQ20

OK, what I REALLY need is an SQL course, but can someone help me?
