我编写此查询以获取基于日期SELECT dbo.Customers.Name, dbo.Items.Name AS ItemName, CONVERT(varchar, dbo.OrderDeliveryDetail.CreatedOn, 1) AS [mm/dd/yy], 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.CreatedOn之和的所有记录。但SQL返回了我需要的所有数据，但他没有给我DeliveredQuantity

的总和

Answer 1

您需要按日期汇总：

SELECT c.Name, i.Name AS ItemName, 
       CONVERT(varchar(10), od.CreatedOn, 1) AS [mm/dd/yy], 
       SUM(od.DeliveredQuantity) AS DeliveredQuantity
FROM dbo.OrderDeliveryDetail od INNER JOIN
     dbo.Customers c
     ON od.BusinessUnitId = c.BusinessUnitId  INNER JOIN
     dbo.Items i
     ON od.BusinessUnitId = i.BusinessUnitId AND
       od.ItemId = i.ItemId
GROUP BY c.Name, i.Name, CONVERT(varchar(10), od.CreatedOn, 1);
-------------------------^

据推测，CreatedOn也有一个时间组件，这会导致每个日期有多行。

另请注意，由于使用了表别名，查询如何更容易理解和。并且，从不在SQL Server中使用varchar()而没有长度。默认长度因上下文而异，您应该明确地防止将来出现错误。

Sql Join Query使用OrderDelivery的总和来获取日期基础上的记录
