Question

如何编写SQL查询以显示输出，如下所示在“所需输出”中。该值必须在每种类型中按降序排列并且并排显示。

Type    Cono    Value
1       100    66.5
1       123    65.6
1       145    56.8
2       145     6
2       100     7
2       123     8

期望的输出：

Rank    Cono    A-value Rank    Cono    B-value
 1     100      66.5    1        123     8
 2     123      65.6    2        100     7
 3     145      56.8    3        145     6

这就是我试过的，

;with cte as
(
  select ROW_NUMBER() over(partition by type order by value desc) Rank,*
  from temp1
)



select
max(CASE when Rank = 1 then rank end) as 'Rank',
max(CASE when Rank = 1 then cono end) as 'Cono',
max(CASE when Rank = 1 then display_value end) as 'A-days',
max(CASE when Rank = 2 then cono end) as 'Rank',
max(CASE when Rank = 2 then cono end) as 'cono'
max(CASE when Rank = 2 then display_value end) as 'B-days'

from cte
group by RANK,cono,value

不确定我是否理解正确，因为似乎所需的输出与样本数据不对应，所以我可能会遗漏某些内容;但是这个或者非常类似的查询应该可以工作：

 select t1.rank, t1.Cono, t1.value 'A-value', t2.rank, t2.Cono, t2.value 'B-value'
 from
 (select *,row_number() over (order by value desc) rank from temp1 where type=1) t1
 join 
 (select *,row_number() over (order by value desc) rank from temp1 where type=2) t2
 on t1.rank=t2.rank

如何排名和并排显示
