Question

我需要计算特定产品代码的总价值。产品代码为5780，一切都低于5700。

要计算值，我使用代码：

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

ELSE部分与报告此部分所需的产品代码有关。

我尝试使用两种不同的公式，它们都返回不同的数量但不是正确的数量。

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分组产品代码，但计算的数字不正确。

示例输出：

    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.

我正在使用Microsoft SQL Sever 2005。如果我需要进一步解释，请告诉我。

整个代码：

DECLARE @Credits Decimal(19,8);
DECLARE @Price Decimal(19,8);

SET @Credits = 41000;
SET @Price = 1.57;

Answer 1

我不确定其他所有事情，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]

使用CASE和OVER计算某些项目的总计
