使用 CASE 和 OVER 计算某些项目的 TOTAL

Question

我需要计算特定产品代码的总值。产品代码为 5780 和低于 5700 的所有内容。

要计算我使用代码的值：

CASE WHEN [PC].[ProductCategoryCode] = 5870 THEN [ICP].[UnitCost] * SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits) OVER (PARTITION BY [PC].[ProductCategoryCode] )
WHEN [PC].[ProductCategoryCode] = 5730 THEN ([ICP].[UnitCost] - 0.25) * SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits) OVER (PARTITION BY [PC].[ProductCategoryCode] )
WHEN [PC].[ProductCategoryCode] = 5990 THEN ([ICP].[UnitCost] * 0 ) * SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits) OVER (PARTITION BY [PC].[ProductCategoryCode] )
ELSE [ICP].[UnitCost] * SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits) OVER (PARTITION BY [PC].[ProductCategoryCode] )
END

ELSEpart 与我在报告的这一部分所需的产品代码相关。

我尝试使用两个不同的公式，它们都返回不同的金额，但不是正确的金额。

一个是：

CASE WHEN [PC].[ProductCategoryCode] = 5780 OR [PC].[ProductCategoryCode] < 5700 THEN SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits * [ICP].[UnitCost] )
OVER ()
END

另一个是：

SUM(Sum([PL].[OriginalQuantity_Stk])  / @Credits * [ICP].[UnitCost]) OVER
       (PARTITION BY (CASE WHEN [PC].[ProductCategoryCode] IN (5870, 5730, 5990)
                           THEN [PC].[ProductCategoryCode] 
                           END) 
       )  

他们通过为每个产品代码显示相同的数字来正确地对产品代码进行分组，但计算出来的数字不正确。

样本输出：

    Product Category Code | Value  |
    5870                  | 100    |
    5730                  | 400    |
    5990                  | 200    |
    5780                  | 200    |
    1111                  | 50     |  
    2222                  | 175    |  
    3333                  | 500    |  
    4444                  | 125    |  

    Total Value: 1050 
It has to ignore product code 5870, 5990, and 5730 and not include 
those in the total value.

我使用的是 Microsoft SQL Sever 2005。 如果我需要进一步解释，请告诉我。

我不确定其他所有情况，但对于案例陈述，我认为这应该适合你

SUM(CASE WHEN [PC].[ProductCategoryCode] = 5780 OR [PC].[ProductCategoryCode] < 5700 THEN [PL].[OriginalQuantity_Stk] ELSE 0 END) / @Credits * [ICP].[UnitCost]
