編寫一個 SQL 查詢來實現分數排名。如果兩個分數相同，則兩個分數排名（Rank）相同。請注意，平分後的下一個名次應該是下一個連續的整數值。換句話說，名次之間不應該有“間隔”。

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

例如，根據上述給定的 Scores 表，你的查詢應該返回（按分數從高到低排列）：

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

select Score,(select count(distinct score) from Scores where score >= s.score) as Rank from Scores s order by score desc

distinct score 去重

{"headers":["Score","Rank"],"values":[[4.0,1],[4.0,1],[3.85,2],[3.65,3],[3.65,3],[3.5,4]]}
