Hi i have a table "copyTable" with 2 columns "id" and "add_1"

i need to update another table "testTable" and update

1. loop through "copyTable"
2. update "testTable"
3. set "testTable.add_1" = "copyTable.add_1"
4. where "testTable.Id" = "copyTable.Id"

just not sure how to do this in a stored proc?

UPDATE testTable
SET testTable.add_1 = copyTable.add_1
FROM copyTable
WHERE testTable.ID = copyTable.ID

Thanks.

use inner join


UPDATE tt
SET tt.add_1 = ct.add_1
FROM testTable tt
INNER JOIN copyTable ct
ON tt.ID = ct.ID
