Question

我的查询旨在将一个名为“WeightFactor”的附加字段添加到表的末尾。我的SQL代码如下。当我尝试运行时，我收到“缺少操作员错误”。我可以在之前的问题中看到OVER（）是一个语法正确的语句。自从我采用rowprice / totalprice以来，“WeightFactor”字段应该是100％的一小部分。当我删除OVER子句时，错误消失但结果只是在每行显示100％，而不是每行100％的正确百分比。

我被警告过，Access中不支持OVER，所以想知道这是否属实，如果有，是否有人知道的解决方法？

SELECT  [2-C: Avg Prices by Customer Number Query].[Part Number],
    [2-C: Avg Prices by Customer Number Query].[Customer Name],
    [2-C: Avg Prices by Customer Number Query].[Customer Number],
    [2-C: Avg Prices by Customer Number Query].SumOfQuantity,
    [2-C: Avg Prices by Customer Number Query].TotalCost,
    [2-C: Avg Prices by Customer Number Query].TotalPrice,
    [2-C: Avg Prices by Customer Number Query].[Gross Margin],
    [TotalPrice] / SUM([TotalPrice]) OVER() AS WeightFactor
FROM    [2-C: Avg Prices by Customer Number Query]

Answer 1

为什么不创建第二个查询来计算所有项目的总数？

'TotalQuery
SELECT SUM([2-C: Avg Prices by Customer Number Query].TotalPrice) AS TotalPriceOver
FROM [2-C: Avg Prices by Customer Number Query];

然后你可以在原始查询中使用这个：

'OriginalQuery
SELECT [2-C: Avg Prices by Customer Number Query].TotalPrice,
[TotalPrice]/[TotalPriceOver] AS WeightFactor
FROM [2-C: Avg Prices by Customer Number Query], TotalQuery;

Access 2007，OVER子句变通方法 - 缺少运算符错误
