The ANSI SQL compliant rewrite of this query would be:

UPDATE Products
SET Stock = (
SELECT Products.Stock - OrdersProducts.Quantity
FROM OrdersProducts
WHERE OrdersProducts.ProductID = Products.ProductID
AND OrdersProducts.OrderID=63116
)
WHERE EXISTS (
SELECT *
FROM OrdersProducts
WHERE OrdersProducts.ProductID = Products.ProductID
AND OrdersProducts.OrderID=63116
)

Since this is standard SQL, it will run on any SQL Server installation,
and should run on any modern RDBMS. It might even run in MS Access.
