Question

我有一个表格，我想要并排显示两次，其中表格按照不同的标准进行过滤。所以这是粗略的（这不是真正的数据）表格现在看起来如何。

Name |1st|2nd|3rd 
-------------------
Mark |1  | 2 | 3
Mark |2  | 4 | 6
Mark |3  | 6 | 8
Tim  |6  | 2 | 4
Tim  |10 | 11| 1

我希望结果看起来像这样：

Name1|1st|2nd|3rd  Name2|1st|2nd|3rd
-------------------------------------
Mark | 1 | 2 | 3  | Tim | 6 | 2 | 4
Mark | 2 | 4 | 6  | Tim | 10| 11| 1
Mark | 3 | 6 | 8  |

所以我可以看到Mark和Tim的结果并排。

当我进行完全外部连接时，我得到它以便我看到表的第一个版本的所有结果，第二个版本为null，结果表中反之低。这是预期的，但我想知道如何尽可能地展示它我想要的方式。使用t-sql。

Answer 1

尝试使用union。

Union避免显示重复数据，但可以将其移动到您要求的列。

如果您可以发布完整查询，我可以更准确地演示。

Answer 2

--creating table
with myTable as (
select 'mark' as Name , 1 as [1st] , 2 as [2nd] , 3 as [3rd]
union 
select 'mark' as Name , 2 as [1st] , 4 as [2nd] , 6 as [3rd]
union 
select 'mark' as Name , 3 as [1st] , 6 as [2nd] , 8 as [3rd]
union 
select 'Tim' as Name , 6 as [1st] , 2 as [2nd] , 4 as [3rd]
union 
select 'Tim' as Name , 10 as [1st] , 11 as [2nd] , 1 as [3rd]
)

--query
select * from (
select ROW_NUMBER()over (order by a.name) as Row , * from myTable as a
where Name= 'Mark' )x
left join  (
select ROW_NUMBER()over (order by a.name) as Row , * from myTable as a 
where Name= 'Tim' )y
on x.Row = y.Row

以下是结果：

Row                  Name 1st         2nd         3rd         Row                  Name 1st         2nd         3rd
-------------------- ---- ----------- ----------- ----------- -------------------- ---- ----------- ----------- -----------
1                    mark 1           2           3           1                    Tim  6           2           4
2                    mark 2           4           6           2                    Tim  10          11          1
3                    mark 3           6           8           NULL                 NULL NULL        NULL        NULL

并排显示相同的表两次，但使用不同的过滤器
