# Rank Scores Problem

## Description

LeetCode Problem 178.

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.

``````1
2
3
4
5
6
7
8
9
10
+----+-------+
| 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):

``````1
2
3
4
5
6
7
8
9
10
+-------+---------+
| score | Rank    |
+-------+---------+
| 4.00  | 1       |
| 4.00  | 1       |
| 3.85  | 2       |
| 3.65  | 3       |
| 3.65  | 3       |
| 3.50  | 4       |
+-------+---------+
``````

Important Note: For MySQL solutions, to escape reserved words used as column names, you can use an apostrophe before and after the keyword. For example `Rank`.

## MySQL Solution

``````1
2
3
4
5
6
select score,
(select count(distinct score) + 1
from scores ss
where ss.score > s.score) `rank`
from scores s
order by score desc
