Question

我正在尝试使用变量来执行计算并将其显示为聚合函数。该公式计算产品的总成本 @PurchaseCost是每磅物品的成本。防爆。 $ 5.50
@Prod_CostLBS是每磅的劳动力成本。防爆。 $ 1.00包装
@InputWeight是多少磅。防爆。 4000个
所有这些变量都由用户输入。要计算我使用公式的总成本：

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

然而，由此我得到错误：

当另一列包含“Group By”的组名称
时，相同的“查看视图”无法显示组名称为“Expression”而没有聚合函数的列

我使用的是Microsoft SQL Server 2005。

完整代码：

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;

Answer 1

你能发布完整的代码吗？试试这个

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

也代替

而不是CAST (@InputWeight - SUM(Sum([IC_ProductLots].[OriginalQuantity_Stk])) OVER () AS DECIMAL(18,2)) AS [Shrink]

使用

 `CAST (@InputWeight - SUM([IC_ProductLots].[OriginalQuantity_Stk])
 AS DECIMAL(18,2)) AS [Shrink]

使用OVER子句和变量时出错
