SQL關係查詢

SELECT dbo.Customers.Name, dbo.Items.Name AS ItemName,SUM(dbo.OrderDeliveryDetail.DeliveredQuantity) AS DeliveredQuantity 
FROM dbo.OrderDeliveryDetail 
INNER JOIN dbo.Customers ON dbo.OrderDeliveryDetail.BusinessUnitId = dbo.Customers.BusinessUnitId 
INNER JOIN dbo.Items ON dbo.OrderDeliveryDetail.BusinessUnitId = dbo.Items.BusinessUnitId AND dbo.OrderDeliveryDetail.ItemId = dbo.Items.ItemId 
GROUP BY dbo.Customers.Name, dbo.Items.Name, dbo.OrderDeliveryDetail.DeliveredQuantity

我寫此查詢，讓我執行查詢時DeliveredQuantity的總和，但他並沒有返回DeliveredQuantity的總和SQL關係查詢

dbo.OrderDeliveryDetail.DeliveredQuantity不應位於group by子句中，因爲您正在對此變量進行求和。

所以嘗試：

SELECT dbo.Customers.Name, dbo.Items.Name AS ItemName,  SUM(dbo.OrderDeliveryDetail.DeliveredQuantity) AS DeliveredQuantity 
FROM   dbo.OrderDeliveryDetail INNER JOIN 
dbo.Customers ON dbo.OrderDeliveryDetail.BusinessUnitId =dbo.Customers.BusinessUnitId INNER JOIN 
dbo.Items ON dbo.OrderDeliveryDetail.BusinessUnitId = dbo.Items.BusinessUnitId AND dbo.OrderDeliveryDetail.ItemId = dbo.Items.ItemId 
GROUP BY dbo.Customers.Name, dbo.Items.Name

SELECT dbo.Customers.Name，dbo.Items.Name AS ITEMNAME，dbo.OrderDeliveryDetail.CreatedOn，SUM（dbo.OrderDeliveryDetail.DeliveredQuantity）AS DeliveredQuantity FROM dbo.OrderDeliveryDetail INNER JOIN dbo.Customers ON dbo.OrderDeliveryDetail.BusinessUnitId = dbo.Customers.BusinessUnitId INNER JOIN dbo.Items ON dbo.OrderDeliveryDetail.BusinessUnitId = dbo.Items.BusinessUnitId AND dbo.OrderDeliveryDetail.ItemId = DBO .Items.ItemId GROUP BY dbo.Customers.Name，dbo.Items.Name，dbo.OrderDeliveryDetail.Create dOn – Ali

我想獲得所有記錄與同一日期..當我把我的查詢日期，他是遞送數量返回總和 – Ali

@Ali請不要在評論中發佈新問題。如果你需要別的東西，請提出一個新問題。 –

從GROUP BY取出DeliveredQuantity，因爲它是一個集合列：

SELECT c.Name, 
     i.Name     AS ItemName, 
     SUM(d.DeliveredQuantity) AS DeliveredQuantity 
FROM dbo.OrderDeliveryDetail d 
     INNER JOIN dbo.Customers c 
       ON d.BusinessUnitId = c.BusinessUnitId 
     INNER JOIN dbo.Items i 
       ON d.BusinessUnitId = i.BusinessUnitId 
        AND d.ItemId = i.ItemId 
GROUP BY c.Name, 
      i.Name
