​LeetCode刷题实战178：分数排名

今天和大家聊的问题叫做 分数排名  ，我们先来看题面：https://leetcode-cn.com/problems/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.

题意

SELECT score,
dense_rank() over(ORDER BY score DESC) as `Rank`
FROM scores;
