Question

我有这个子查询，需要返回每个机架的SUM（qty），然后按最早的最早日期（ASC）对机架/箱进行排序。每当我使用日期字段对数据进行排序时，它都会为每个日期返回一条记录。我在SELECT语句中添加了日期字段以供参考。我将如何去做？

SELECT InventoryItems_1.ItemID,
       SUM(ISNULL(InventoryItems_1.QtyToStock, 0)) AS InvQty,
       InventoryItems_1.Rack,
       InventoryItems_1.Bin,
       InventoryItems_1.LocationID,
       MIN(InventoryItems_1.Date),
       Locations_1.LocationCode,
       Locations_1.DescriptionMed
FROM dbo.InventoryItems AS InventoryItems_1
     INNER JOIN dbo.Locations AS Locations_1 ON InventoryItems_1.LocationID = Locations_1.LocationID
WHERE(InventoryItems_1.OwnerDetailID IS NULL)
GROUP BY InventoryItems_1.ItemID,
         InventoryItems_1.LocationID,
         InventoryItems_1.Rack,
         InventoryItems_1.Bin,
         InventoryItems_1.Date,
         Locations_1.LocationCode,
         Locations_1.DescriptionMed
HAVING InventoryItems_1.ItemID = 10308
ORDER BY InventoryItems_1.LocationID,
         InventoryItems_1.Date,
         InventoryItems_1.Rack,
         InventoryItems_1.Bin;

这是我的结果：

10308   35      21      02-Z    7   2018-10-22 14:48:33.000     WI

这就是我想要的样子，首先按最早的库存日期排序。

Answer 1

您正在按InventoryItems_1.Date字段进行分组，这就是为什么每个日期都有单独的行出现的原因。以此将查询更改为“不分组”，并命名最小日期字段将使您生成正确的输出。另外，如果要将报告限制为仅一个ID，请将其放在WHERE子句中，而不要放在HAVING子句中。这将在执行GROUP BY计算等之前过滤记录，从而加快输出速度。

SELECT InventoryItems_1.ItemID,
       SUM(ISNULL(InventoryItems_1.QtyToStock, 0)) AS InvQty,
       InventoryItems_1.Rack,
       InventoryItems_1.Bin,
       InventoryItems_1.LocationID,
       MIN(InventoryItems_1.Date) As MinDate,
       Locations_1.LocationCode,
       Locations_1.DescriptionMed
FROM dbo.InventoryItems AS InventoryItems_1
INNER JOIN dbo.Locations AS Locations_1 
    ON InventoryItems_1.LocationID = Locations_1.LocationID
WHERE InventoryItems_1.OwnerDetailID IS NULL
    AND InventoryItems_1.ItemID = 10308

GROUP BY InventoryItems_1.ItemID,
         InventoryItems_1.LocationID,
         InventoryItems_1.Rack,
         InventoryItems_1.Bin,
         Locations_1.LocationCode,
         Locations_1.DescriptionMed
-- HAVING InventoryItems_1.ItemID = 10308
ORDER BY InventoryItems_1.LocationID,
         MIN(InventoryItems_1.Date),
         InventoryItems_1.Rack,
         InventoryItems_1.Bin;

Answer 2

您可以这样做：

SELECT 
    InventoryItems_1.ItemID
,   ISNULL(InventoryItems_1.QtyToStock, 0) AS InvQty
,   InventoryItems_1.Rack
,   InventoryItems_1.Bin
,   InventoryItems_1.LocationID
,   InventoryItems_1.Date
,   Locations_1.LocationCode
,   Locations_1.DescriptionMed
FROM (
    SELECT *, ROW_NUMBER() OVER(PARTITION BY ItemID, Bin, LocationID ORDER BY [Date] DESC) RN 
    FROM dbo.InventoryItems 
) InventoryItems_1
INNER JOIN dbo.Locations AS Locations_1 ON InventoryItems_1.LocationID = Locations_1.LocationID
WHERE
    InventoryItems_1.RN = 1
AND InventoryItems_1.OwnerDetailID IS NULL
AND InventoryItems_1.ItemID = 10308
ORDER BY InventoryItems_1.LocationID,
         InventoryItems_1.Rack,
         InventoryItems_1.Bin;

最早日期的订单位置，不返回每个日期戳的记录
