Sql server SQL组合公式时总计不正确

对于我正在创建的报表，我需要使用两个单独的表达式，并将它们组合成一个解决方案

我需要的第一个表达式是总销售额，由

Sum([DCT].[Quantity_Stk] *[ICP].[UnitCost]) AS [Total Sales]

 Max(CAST ((@PurchaseCost + @Prod_CostLBS) * @InputWeight AS DECIMAL (18,2))) AS [Cost]

我需要的第二个表达式是总成本，由

Sum([DCT].[Quantity_Stk] *[ICP].[UnitCost]) AS [Total Sales]

 Max(CAST ((@PurchaseCost + @Prod_CostLBS) * @InputWeight AS DECIMAL (18,2))) AS [Cost]

这两条语句都可以工作，因为它们用于查询中的其他列，并且可以正确显示

为了找出总利润，我尝试使用SUM、AVG、MAX和将其组合成一个表达式，但结果是一个错误。我相信下面的代码有正确的想法，它只是缺少一些重要的部分。也许是一种过度的说法：

CAST (([DCT].[Quantity_Stk] *[ICP].[UnitCost]) - ((@PurchaseCost + @Prod_CostLBS) * @InputWeight) AS DECIMAL(18,2)) AS [Profit]

DECLARE @TotalSales decimal(19,8) = (SELECT Sum([Total Sales]) FROM #TempTable
DECLARE @TotalProfit decimal(19,8) = (SELECT SUM([Profit]) FROM #TempTable
DECLARE @TotalCost decimal(19,8) = (SELECT SUM([Cost]) FROM #TempTable

我的问题是，它正在计算每行的利润，但我只想要总利润。我相信这会使它成为一个聚合函数。或者有没有办法将另外两个表达式存储为变量并使用它们

我正在使用Microsoft SQL Server 2005

SET @InputWeight = 18100;
SET @Prod_CostLBS  = .15;

声明变量：

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

SET @PurchaseCost = 2.58;
SET @InputWeight = 18100;
SET @Prod_CostLBS  = .15;

将所有原始数据放入临时表，如下所示：

    SELECT 
         CAST([ARC].[CustomerCode] AS NVARCHAR(40)) + ' - ' + CAST([ARC].[Name] AS NVARCHAR(40)) AS [Supplier]

您是否试图获得所有产品的总利润？意思是每行显示相同的值？在这种情况下，您可以使用[your table]中的嵌套Select SUM[your formula]作为总计Profit@Samcd是的，不一定每一行都显示相同的值，因为我会将其铸造为标题，但是是的，总利润应该只有一个值，整个报告应该是相同的。这有意义吗？为什么要用MAX？@Samcd作为第二个表达式？因为这是我能让它正常工作的唯一方法。嗯，正确设置值的格式，但是数字太离谱了。这可能是我这边的一个错误。以这种方式声明变量的问题是，我不能在集合中使用WHERE语句，因为WHERE根据用户输入而变化。您能否将没有聚合的基本数据放入临时表中，然后从那里进行计算？我不这么认为，因为我公司使用的程序不允许我添加表格。所有表都已预构建。创建临时表不需要权限。从[…]中选择[…]到EntertableName。该表将在会话关闭时删除
