Question

我是新手，我正在尝试根据表格中的信息创建报告。以下是表格中当前数据的示例...

id      Date          Name       Location      Model      Count
 1      06/10/2012    William    Basement      Desktop    22
 2      06/10/2012    Doug       Top Floor     Desktop    15
 3      06/10/2012    Jane       Top Floor     Laptop     12
 4      06/11/2012    William    Basement      Desktop    29
 5      06/11/2012    Doug       Top Floor     Desktop    35
 6      06/12/2012    William    Basement      Desktop    31
 7      06/12/2012    Doug       Top Floor     Desktop    41
 8      06/12/2012    Jane       Top Floor     Laptop     24

现在我要做的是创建一个报告，该报告将按月分组并累计计数，计算最后一个计数并从记录的月份的第一天减去第一个计数。因此，我的报告应该看起来像这样，遗漏ID，因为这不是报告的必要数据。

Date          Name       Location      Model      Count
June 2012     William    Basement      Desktop    9
June 2012     Doug       Top Floor     Desktop    26
June 2012     Jane       Top Floor     Laptop     12

如果有人有任何想法我怎么能做到这一点，记住我很新，访问，这将是伟大的！

您可以先创建一个查询，然后根据该查询创建报告。包含一个可以设置为MaxOfCount和MinOfCount之间差异的控件。

SELECT DISTINCT Format([Date],"yyyy mm") AS Sort, 
       Format([Date],"mmm yyyy") AS [Month], 
       a.Name, a.Location, a.Model, 
       (SELECT TOP 1 [Count] 
        FROM Report b 
        WHERE a.Name=b.Name AND a.Location=b.Location AND a.Model=b.Model 
        ORDER BY [Date] DESC, Id) As MaxOfCount, 
       (SELECT TOP 1 [Count] 
        FROM Report b 
        WHERE a.Name=b.Name AND a.Location=b.Location AND a.Model=b.Model 
        ORDER BY [Date], Id) AS MinOfCount
FROM Report a
