This is a template maybe it can help:

UPDATE U
SET MyColumn = 'XXX'
FROM MyTable U

or


UPDATE U
SET TableA_ColA = TableB_ColB
FROM MyTableA U
JOIN MyTableB
ON TableB_ColPK = TableA_ColPK

Hi

I have to ask you because I havn't a good solution for this.

I have table F0901 with key fields: GMMCU, GMOBJ and GMSUB and one field
GMR015 which I would like to update.
The source table is FUPD02 with key fields: UPMCU, UPOBJ and UPSUB and
source_update field UPR015.

I check many source but always have some errors; my latest statements is:

UPDATE F0901
SET GMR015 =
(SELECT UPR015 FROM FUPD02 WHERE
GMMCU!!GMOBJ!!GMSUB=UPMCU!!UPOBJ!!UPSUB)
WHERE EXIST
(SELECT UPMCU!!UPOBJ!!UPSUB FROM FUPD02 WHERE
GMMCU!!GMOBJ!!GMSUB=UPMCU!!UPOBJ!!UPSUB)

Have you idea how to change this statement?
