sql-server-2008 - 从同一张表中选择男性和女性的名字

Question

这是我的“联系人”表。

| Names      |   Gender   |

| Mike       | Male       |
| Steve      | Male       |
| Kelly      | Female     |
| Jane       | Female     |
| Natasha    | Female     |
| Mathew     | Male       |
| Jack       | Male       |

我想要这样的结果：

|  Male      |   Female   |   

| Mike       | Kelly      |
| Steve      | Jane       |
| Mathew     | Natasha    |
| Jack       |            |

请给我解决方案以在 SQL Sever 中实现此结果...任何建议表示赞赏！

Answer 1

with Male as
(
  select Names,
         row_number() over(order by Names) as rn
  from YourTable
  where Gender = 'Male'
),
Female as
(
  select Names,
         row_number() over(order by Names) as rn
  from YourTable
  where Gender = 'Female'
)
select Male.Names as Male,
       Female.Names as Female
from Male
  full outer join Female
    on Male.rn = Female.rn

不是您想要的确切结果，但在没有另一列可供订购的情况下得到的结果一样好。
