Ms access MS Access将行信息转换为列信息

ms-access vba

Ms access MS Access将行信息转换为列信息,ms-access,vba,rows,Ms Access,Vba,Rows,我花了好几个小时想弄明白这一点。这是为一家制造厂准备的车间人员使用计算机系统在不同的机器上记录他们的活动，该计算机系统生成如下数据： Empnbr Datestamp Shift Machnbr Time 00090 6/30/2010 1 0354 11:10 00090 6/30/2010 1 S 12:00 00098 6/30/2010 1 0920 7:00 00098 6/30/2010 1 0143

我要写的报告需要这样一种形式的信息

Empnbr      Datestamp      Shift      Time Start       Time End       Machine

这将允许我计算每人每天在每台机器上花费的时间量。基本上，Access需要查看员工编号、日期戳和班次，并在第一次看到时进行查看。然后需要获取下一次看到的时间，并在第一次输入时将该时间归因于机器。这种情况持续发生，直到访问遇到机器S，这意味着注销

现在是时候吃点止痛药了-谢谢你的帮助

我会用一张临时桌子。要显示报告时，请使用VBA代码浏览输入表、生成报告数据并填充临时表。然后使用临时表中的数据显示报告。填充报告表的函数如下所示：

分组查询不适合的原因有哪些？例如：

SELECT Empnbr, Datestamp, Shift, Machnbr, 
       Min(CDate([datestamp] & " " & [Time])) AS TimeStart, 
       Max(CDate([datestamp] & " " & [Time])) AS TimeEnd
FROM MachineLog 
GROUP BY Empnbr, Datestamp, Shift, Machnbr

编辑再评论

也许：

SELECT m.Empnbr, m.Datestamp, m.Shift, m.Machnbr, 
     Nz((SELECT Max(CDate([datestamp] & " " & [Time])) 
         FROM MachineLog x WHERE x.Empnbr=m.Empnbr 
         AND x.Machnbr<m.Machnbr),CDate([datestamp] & " 08:00")) AS st, 
     Max(CDate([datestamp] & " " & [Time])) AS TimeEnd
FROM MachineLog m
GROUP BY m.Empnbr, m.Datestamp, m.Shift, m.Machnbr

因为结束时间将具有不同的机器编号。一台机器的开始时间是前一台机器的结束时间。
