从同一个表中选择男性和女性的姓名

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
