If you're taking the custaddtest then that would be:


UPDATE
    OT
SET
   OT.name = T.name
 
FROM
    CustAddTest T
INNER JOIN
    TEST_DeliveryAddress OT
ON
    T.[Customer] = OT. [Cust_Number] AND T.cust_seq=0

Open in new window


ensure you're getting that by running this:

select
   OT.name oldName, T.name newName
 FROM
    CustAddTest T
INNER JOIN
    TEST_DeliveryAddress OT
ON
    T.[Customer] = OT. [Cust_Number] AND T.cust_seq=0

Open in new window

You are updating the TEST_DeliveryAddress.name column with the TEST_DeliveryAddress.name column.  There isn't going to be any  change.
