分组数据TSQL

我正在尝试制作一份显示用户提交表单的报告。分组数据TSQL

我希望每行显示每个用户每个字段的出现次数。

用户名|首先提交表格|表格地址（第一表格）|最后提交表格|申请表地址（最后形式）

这里就是我有目前：

SELECT form.Name 
      ,(SELECT COUNT (*) FROM dbo.vAdvF_155 af WHERE af.Name = form.Name) AS [TotalForms] 
      ,(SELECT TOP 1 p.Timetag1 FROM dbo.vAdvF_155 af WHERE af.Name = form.Name ORDER BY [TimeTag1] ASC) AS [Started] 
      ,(SELECT TOP 1 af.aField143 FROM dbo.vAdvF_155 af WHERE af.TimeTag1 = form.TimeTag1 ORDER BY [TimeTag1] DESC) AS [FirstFormAddress] 
      ,(SELECT TOP 1 p.Timetag2 FROM dbo.vAdvF_155 af WHERE af.Name = form.Name ORDER BY [TimeTag2] DESC) AS [Submitted] 
      ,(SELECT TOP 1 af.aField143 FROM dbo.vAdvF_155 af WHERE af.RecId = form.RecId ORDER BY [TimeTag2] DESC) AS [LastFormAddress] 

FROM   dbo.vAdvF_155 AS form INNER JOIN 
      dbo.PhoneData AS p ON form.RecId = p.RecID 
      ORDER BY form.Name

结果：

正如你的结果看到它显示的所有形式，因为他们并不是很明显，我从字面上看只是希望将它分组为每人一行，但无法确定分组。

你能提供源表和对数据的选择在他们内部？做这么多的子选择通常是一个坏主意...... 你的数据有重复，因为你根本没有在你的ORDER BY之前使用'GROUP BY'语句，看起来你需要应用一些额外的过滤在你的“表格”表中，因为它将所有行都拉回来。 – iamdave

假设了很多关于你的vAdvF_155表/视图的结构，你可以得到你正在寻找这样的结果：

declare @vAdvF_155 table (Name nvarchar(50) 
          ,aField143 nvarchar(50) 
          ,Timetag1 datetime 
          ,Timetag2 datetime 
          ) 
insert into @vAdvF_155 values 
('CARL SUTTON' ,'4 Archway Old Clipstone' ,'2016-07-31 12:49:29.000','2016-07-31 14:07:05.000') 
,('CARL SUTTON' ,'5 RAVENSHEAD COURT'  ,'2016-08-01 08:20:21.000','2016-08-01 10:08:39.000') 
,('CARL SUTTON' ,'Field CLOSE GEDLING'  ,'2016-08-02 07:56:23.000','2016-08-02 09:48:13.000') 
,('CASEY MORTON','10 ByRON CRESENT Ng162sx' ,'2016-07-22 09:12:08.000','2016-07-22 11:42:30.000') 
,('CASEY MORTON','146 Street Name'   ,'2016-07-22 13:27:12.000','2016-07-22 16:05:29.000') 
,('CASEY MORTON','5 Cossall Road NG93PG' ,'2016-07-25 09:14:37.000','2016-07-25 14:16:53.000') 


select f.Name 
     ,f.TotalForms 
     ,f.FirstForm 
     ,ff.aField143 as FirstFormAddress 
     ,f.LastForm 
     ,lf.aField143 as LastFormAddress 
from (
    select Name 
      ,count(1) as TotalForms 
      ,min(Timetag1) as FirstForm 
      ,max(Timetag2) as LastForm 
    from @vAdvF_155 
    group By Name 
    ) f 
    inner join @vAdvF_155 ff 
     on(f.Name = ff.Name 
      and f.FirstForm = ff.Timetag1 
      ) 
    inner join @vAdvF_155 lf 
     on(f.Name = ff.Name 
      and f.LastForm = lf.Timetag2 
      )

正如你所说，我认为我使所有的子查询太复杂了。我已经打破了代码，看看它是如何工作（你的答案），并根据需要带回结果。非常感谢您的帮助！ – Benzz
