计算的聚合函数错误

Question

对于我正在创建的报告，我需要计算出 SUM 并将其用于另一个方程式。该方程用于计算 Shrink，这与差异是一回事。要计算收缩率，我使用：

@InputWeight - Sum([IC_ProductLots].[OriginalQuantity_Stk]) AS [Shrink]

输入权重由用户在运行报告前给出。因此，例如，如果输入重量为 15,000，而原始数量的 SUM 为 14,800，则 Shrink 应为 200。

问题是该代码正在为每一行计算收缩，每个报告应该只有一个收缩。

示例输出如下所示：

Input Weight: 15,000
Product # | Weight | Shrink
1234      | 7,000  | 
1235      | 6,500  | 
1236      | 500    | 
1237      | 800    | 
--------------------------
TOTAL     |14,800  | 200

我正在使用 Microsoft SQL Server 2005。

如果有帮助，下面是我的完整代码：

SET NOCOUNT ON; 
DECLARE @PurchaseCost Decimal(19,8);
DECLARE @InputWeight Decimal(19,8);

SET @PurchaseCost = 1;
SET @InputWeight = 15000;
    SELECT DISTINCT 
         CAST([ARC].[CustomerCode] AS NVARCHAR(40)) + ' - ' + CAST([ARC].[Name] AS NVARCHAR(40)) AS [Supplier]
       , [PC].ProductCode
       , [PC].Description1
       , Count(IC_ProductLots.OriginalQuantity_Alt) AS [Boxes]
       , IC_ProductLots.UnitOfMeasure_Alt
       , Sum(IC_ProductLots.OriginalQuantity_Stk) AS [Weight]
       , IC_ProductLots.UnitOfMeasure_Stk
       , [ICP].UnitCost AS [Unit Cost]
       , Sum(ROUND([DCT].[Quantity_Stk] *[ICP].[UnitCost], 2)) AS [Total Sales]
       , Avg(([IC_ProductLots].[OriginalQuantity_Stk] / [IC_ProductLots].[OriginalQuantity_Alt])) AS [Avg. Box Weight]
       , Sum([IC_ProductLots].[OriginalQuantity_Stk] / @InputWeight) AS [Yield]
       , @InputWeight - Sum([IC_ProductLots].[OriginalQuantity_Stk]) AS [Shrink]
     FROM (((( IC_Products [PC] 
        INNER JOIN  DC_Transactions [DCT] 
         ON [PC].ProductKey = [DCT].ProductKey)
        INNER JOIN  AR_Customers [ARC] 
         ON [DCT].CustomerKey = [ARC].CustomerKey)
        INNER JOIN  IC_ProductLots 
         ON [DCT].LotKey = IC_ProductLots.LotKey)
        LEFT OUTER JOIN  IC_ProductCosts [ICP] 
         ON ICP.ProductKey=PC.ProductKey and ICP.ProductCostCode=5)
     WHERE 
        (IC_ProductLots.ProductionDate >= { ts '2015-06-29 00:00:00' }   AND (IC_ProductLots.ProductionDate <= { ts '2015-06-29 00:00:00' } OR IC_ProductLots.ProductionDate Is Null)) 
    AND ([ARC].CustomerCode = '         904') 
     GROUP BY 
         CAST([ARC].[CustomerCode] AS NVARCHAR(40)) + ' - ' + CAST([ARC].[Name] AS NVARCHAR(40))
       , [PC].ProductCode
       , [PC].Description1
       , IC_ProductLots.UnitOfMeasure_Alt
       , IC_ProductLots.UnitOfMeasure_Stk
       , [ICP].UnitCost
       , IC_ProductLots.ProductionDate
       , [ARC].CustomerCode
     ORDER BY 
         CAST([ARC].[CustomerCode] AS NVARCHAR(40)) + ' - ' + CAST([ARC].[Name] AS NVARCHAR(40))

基本上，我需要计算总收缩量而不是每一行的收缩量。

更新：

我尝试使用

@InputWeight - Sum([IC_ProductLots].[OriginalQuantity_Stk]) OVER(PARTITION BY [ARC].[CustomerCode]) AS [Shrink]

但我收到错误："Column 'IC_ProductLots.OriginalQuantity_Stk' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."

Answer 1

我觉得你想要的表达方式是：

@InputWeight - SUM(Sum([IC_ProductLots].[OriginalQuantity_Stk])) OVER ()

注意：您不需要将 select distinct 与 group by 一起使用，因此您应该删除不同的。
