Sql server 如何在连接多个表时避免重复,sql-server,Sql Server,该表包含三条记录，见以下临时表： Declare @TimeStamp table (Id int, SalesMan_ID int, Module_Cdoe varchar(50),Time_In varchar(10),Time_Out varchar(10)) Insert into @TimeStamp values (1,13524,'Analysis','1:30pm','1:40pm'), (2,12543,'Analysis','2:10pm','2:30pm'), (3,12

该表包含三条记录，见以下临时表：

Declare @TimeStamp table (Id int, SalesMan_ID int, Module_Cdoe varchar(50),Time_In varchar(10),Time_Out varchar(10))

Insert into @TimeStamp values
(1,13524,'Analysis','1:30pm','1:40pm'),
(2,12543,'Analysis','2:10pm','2:30pm'),
(3,12543,'Analysis','3:10pm','3:30pm')


;with cteBase (Seq,Module_Cdoe) as(
    Select 1,'Photo' union all
    Select 2,'Survey' union all
    Select 3,'Merchand'
)
Select id=Row_Number() over (Order By Time_In,SalesMan_id,Seq)
      ,SalesMan_id
      ,b.Module_Cdoe
      ,Time_In
      ,Time_Out
 from @TimeStamp A
 Join cteBase B on (A.Module_Cdoe='Analysis')
 Order By 1

根据上述查询，结果为：

id  SalesMan_id Module_Cdoe Time_In Time_Out
1   13524       Photo       1:30pm  1:40pm
2   13524       Survey      1:30pm  1:40pm
3   13524       Merchand    1:30pm  1:40pm
4   12543       Photo       2:10pm  2:30pm
5   12543       Survey      2:10pm  2:30pm
6   12543       Merchand    2:10pm  2:30pm
7   12543       Photo       3:10pm  3:30pm
8   12543       Survey      3:10pm  3:30pm
9   12543       Merchand    3:10pm  3:30pm

但我需要如下所示：

id  SalesMan_id Module_Cdoe Time_In Time_Out
1   13524       Photo       1:30pm  1:40pm
2   13524       Survey      1:30pm  1:40pm
3   13524       Merchand    1:30pm  1:40pm
4   12543       Photo       2:10pm  2:30pm
5   12543       Survey      2:10pm  2:30pm
6   12543       Merchand    2:10pm  2:30pm

（或）

那么，什么样的查询才能达到我的期望呢？

根据要求，这只是对原始查询的一个小改动

您想显示较早的时间还是较晚的时间。最好指定其中一个。如果你不关心它们，你需要它们吗？如果没有，您可以使用groupingI need the later times更新问题以指定此选项，然后更改id以匹配您的期望值中稍后的行output@AlexandarR好的，从原来的一个小扭曲。我看到分析不见了，“锚”现在是照片吗？你想显示早期还是晚期。最好指定其中一个。如果你不关心它们，你需要它们吗？如果没有，您可以使用groupingI need the later times更新问题以指定此选项，然后更改id以匹配您的期望值中稍后的行output@AlexandarR好的，从原来的一个小扭曲。我看到分析不见了，“锚”现在是照片吗？
