MySQL - 根据出现次数最多的人名

给定:

名为 names 的表，包含 id、first 和 last 字段。

当 first 和 last 是单独的字段时，您如何找到前 5 个最受欢迎的人？这是我现在的非工作代码...

`SELECT *, COUNT(first) AS occurrences FROM `names` GROUP BY first ORDER BY occurrences DESC LIMIT 5`

如有任何帮助，我们将不胜感激!

最佳答案

对于前 5 个名字，尝试:

SELECT first, COUNT(*) AS occurrences 
FROM names
GROUP BY first 
ORDER BY occurrences DESC 
LIMIT 5

对于前 5 个名字，尝试:

SELECT first, last, COUNT(*) AS occurrences 
FROM names
GROUP BY first, last
ORDER BY occurrences DESC 
LIMIT 5
