Hi Peter
try the following
(COMPLETELY UNTESTED)
UPDATE ITEMBL A SET A.ITCLS =
(SELECT ITCLS FROM ITMRVA B
WHERE A.ITNBR = B.ITNBR AND B.STID = 'J2P' AND A.ITCLS <> B.ITCLS AND
A.HOUSE = 'JTG')
WHERE EXISTS
(SELECT * FROM ITMRVA B
WHERE A.ITNBR = B.ITNBR AND B.STID = 'J2P' AND A.ITCLS <> B.ITCLS AND
A.HOUSE = 'JTG')

Hi list!
This is "my complication" on this simple SQL:
=======================================================
FILE:ITEMBL
FIELDS:
ITNBR - ITEM NUMBER (KEY FIELD)
HOUSE - WAREHOUSE (KEY FIELD)
ITCLS - ITEM CLASS
FILE:ITMRVA
FIELDS:
ITNBR - ITEM NUMBER (KEY FIELD)
STID - SITE ID
ITCLS - ITEM CLASS
Goal: Update ITCLS in ITEMBL with ITCLS in ITMRVA only if:
a) STID = 'J2P'
b) HOUSE = 'JTG'
c) ITEMBL.ITCLS <> ITMRVA.ITCLS
=======================================================
This is the SQL I am doing:
UPDATE ITEMBL A SET A.ITCLS =
(SELECT ITCLS FROM ITMRVA B
WHERE A.ITNBR = B.ITNBR AND B.STID = 'J2P' AND A.ITCLS <> B.ITCLS)
WHERE A.ITNBR = B.ITNBR AND A.HOUSE = 'JTG'
?
The error I am having is: COLUMN QUALIFIER OR TABLE B UNDEFINED. If I
remove the "B" qualifier from the last B.ITNBR in the SQL, then I have
this error instead: NULL VALUES NOT ALLOWED IN COLUMN OR VARIABLE ITCLS.
I can't see what I am doing wrong ... HELP! Thanks in advance!
