Rank Scores

Write a SQL query to rank scores. If there is a tie between two scores, both should have the same ranking. Note that after a tie, the next ranking number should be the next consecutive integer value. In other words, there should be no "holes" between ranks.

+----+-------+
| Id | Score |
+----+-------+
| 1  | 3.50  |
| 2  | 3.65  |
| 3  | 4.00  |
| 4  | 3.85  |
| 5  | 4.00  |
| 6  | 3.65  |
+----+-------+

For example, given the above Scores table, your query should generate the following report (order by highest score):

+-------+------+
| Score | Rank |
+-------+------+
| 4.00  | 1    |
| 4.00  | 1    |
| 3.85  | 2    |
| 3.65  | 3    |
| 3.65  | 3    |
| 3.50  | 4    |
+-------+------+

大概意思就是写sql语句,查出每个分数的排名。

我的mysql语句:

select d.Score,c.Rank from Scores d,
(select Id,Score,(select count(Score) from (select Id,Score from Scores group by Score) b where b.Score>=a.Score) as Rank from
(select Id,Score from Scores group by Score) a) c
where d.Score=c.Score order by d.Score desc
