Table_1:
| Id | Score |
|---|---|
| 1 | 3.50 |
| 2 | 3.65 |
| 3 | 4.00 |
| 4 | 3.85 |
| 5 | 4.00 |
| 6 | 3.65 |
答:
select a.Score as Score,
(select count(distint b.Score) from Table_1 b where b.Score >= a.Score) as Rank
from Tabel_1 a
order by a.Score DESC;
内容解释:
- 先通过
where b.Score >= a.Score把符合条件的筛选出来,也就是把当前分数和所有分数做对比,只把前面(大于)的部分拿出来,去重后就是排名
函数解释:
- DESC: 降序排列
- distint :去重
