If i'm not wrong, below query should do the job:

SQL

UPDATE Article t1 SET stock = (SELECT [received goods] AS stock FROM [Order] t2 WHERE t2.articlenumber = t1.articlenumber)

It's strongly recommended to change the name of Order table, because it is one of reserved words of Oracle database[^]! You can use Orders instead.
