Question

我无法在此代码中找到错误。

UPDATE order_items o
set (DISCOUNT_AMOUNT) =
select T.maxdiscount
from (select customer_id , o.order_id as order_id, D.product_id as product_id, D.total, E.maxdiscount as maxdiscount
from orders o, (select sum(quantity)as total, order_id, product_id
from order_items
group by order_id, product_id)  D,
(select max(discount_amount)  as maxdiscount, product_id
from order_items
group by product_id) E
where o.order_id  = D.order_id and E.product_id = D.product_id) T
where exists T.order_id = o.order_id and T.product_id = o.product_id;

我得到的信息是：
