mysql - mysql查询 - 计算类似术语

Question

我的 MySQL 表如下：

ID  term  timestamp

1   foo    xxxx
2   bar    xxxx
3   bar    xxxx
4   foo    xxxx
5   foo    xxxx
6   foo    xxxx
7   xxx    xxxx

我希望生成一个列表，按该术语的数量顺序显示最常用的术语

即最终结果：

foo 
bar
xxx

我应该使用什么查询？我做了一些谷歌搜索，但我不太确定我在寻找什么 - COUNT / GROUP BY 等。

GROUP BY是正确的。试试这个：

SELECT term FROM table
GROUP BY term
ORDER BY COUNT(term) desc

HAVING COUNT(*) > 5 --replace with number you want
ORDER BY COUNT(*)

这个 SQL 查询应该这样做：

SELECT term FROM my_table GROUP BY term ORDER BY COUNT(term) DESC;
