MYSQL排名分区

Question

我有这张桌子

| Name      | Born      | Live      | Age   |
|--------   |-------    |--------   |-----  |
| John      | UK        | UK        | 10    |
| Smith     | UK        | France    | 12    |
| Ben       | Spain     | Spain     | 15    |
| George    | Spain     | UK        | 25    |
| Ann       | UK        | UK        | 27    |
| Cassie    | Spain     | Spain     | 30    |

我想要这个

| Name      | Born      | Live      | Age   | | Rank |
|--------   |-------    |--------   |-----  | |------|
| John      | UK        | UK        | 10    | |  1   |
| Ann       | UK        | UK        | 27    | |  2   |
| Smith     | UK        | France    | 12    | |  1   |
| Ben       | Spain     | Spain     | 15    | |  1   |
| Cassie    | Spain     | Spain     | 30    | |  2   |
| George    | Spain     | UK        | 25    | |  1   |

所以我希望通过出生和生活获得排名。

我知道在SQL中我们可以使用RANK AND PARTITION，但在MYSQl中我找不到这样做的方法。有人可以帮忙吗？

Answer 1

我想你应该看一下：Rank function in MySQL

希望它会对你有帮助;）！

Answer 2

SELECT Name, Born, Live,Age, 
   @rank := IF(@prev_born = Born, @rank + 1,1) AS Born_rank,
   @prev_Born := Born
FROM TABLE,(select @prev_born :=0,@rank :=0)  r
ORDER BY Born, Age ASC
