[英]Display the order total and the number of products sold for order number
我希望有人可以幫助我朝正確的方向發展嗎? 我正在嘗試編寫一個查詢,其中報告將顯示該訂單號的訂單總數和已售產品數量,我粘貼了現有商品,並希望我走上了正確的道路。 提前致謝!
select distinct od.OrderID, AVG( od.unitprice * od.quantity / od.Discount) 'try',
od.ProductID
from OrderDetails od
where od.OrderID = 10251
group by od.orderid
顯示訂單總數和該訂單號出售的產品數量
應該這樣做:
SELECY OrderID, -- Order Id
count(*) as items, -- number of products
SUM(unitprice * quantity / Discount) as total -- order total
FROM OrderDetails
WHERE OrderID = 10251
GROUP BY OrderID
