Mysql 如何命名在SQL中也是函数名的列？

例如，这不起作用

SELECT a.score, a.r as Rank FROM 
    (SELECT score, dense_rank() over (order by Score desc) as r
        FROM Scores) a
ORDER BY a.r;

---

这是因为

Rank

也是一个函数。我试图用

[Rank]

替换

Rank

，但仍然不起作用。那么，解决方案是什么呢？

您可以给它一个不同的名称。这就是我的建议。但如果没有，MySQL中的转义字符是backtick：

SELECT a.score, a.r as `Rank`
FROM (SELECT score, dense_rank() over (order by Score desc) as r
      FROM Scores
     ) s
ORDER BY a.r;

或SQL标准，双引号：

SELECT a.score, a.r as "Rank"
FROM (SELECT score, dense_rank() over (order by Score desc) as r
      FROM Scores
     ) s
ORDER BY a.r;
