Question

我需要获得Alias专栏的％保证金，并且它让我烦恼，我说得不对，而且可能很简单。

我的查询是我正在使用的内容，我通过从OH.TotalSellPrice列中减去OH.TotalCostPrice来创建了列Profit。我需要获得％保证金，因此我需要SUM新创建的列，将其除以OH.TotalSellPrice列，然后* 100以获得保证金。

    SELECT U.Name AS [Created By], 
    SUM(OH.TotalSellPrice) as [Sale value],
    SUM (OH.TotalSellPrice-OH.TotalCostPrice) as [Profit], 
    COUNT(OH.OrderID) / 100 AS ID1
    FROM OrderHeader AS OH WITH(NOLOCK)
    LEFT JOIN Users AS U WITH(NOLOCK) ON U.UserID = OH.CreatedByID
    WHERE OH.Deleted = 0 AND OH.OrderType = 1 
and U.UserID in (129,245,336,337,378,387,388,425,427,433,458,480, 489, 370,458)
    and OH.Invoiced=1
    GROUP BY U.Name

Answer 1

您必须对聚合值而不是别名列名进行计算，如下所示：

(SUM(OH.TotalSellPrice-OH.TotalCostPrice) / 
 SUM(OH.TotalSellPrice))*100 AS PercentageMargin

因此完整查询将如下所示：

SELECT U.Name AS [Created By], 
    SUM(OH.TotalSellPrice) as [Sale value],
    SUM (OH.TotalSellPrice-OH.TotalCostPrice) as [Profit], 
    COUNT(OH.OrderID) / 100 AS ID1,
    (SUM (OH.TotalSellPrice-OH.TotalCostPrice) / 
     SUM(OH.TotalSellPrice))*100 AS PercentageMargin
FROM OrderHeader AS OH WITH(NOLOCK)
    LEFT JOIN Users AS U WITH(NOLOCK) ON U.UserID = OH.CreatedByID
    WHERE OH.Deleted = 0 AND OH.OrderType = 1 
and U.UserID in (129,245,336,337,378,387,388,425,427,433,458,480, 489, 370,458)
    and OH.Invoiced=1
    GROUP BY U.Name

对已经有计算的别名列求和
