mysql - 计算 DISTINCT 值的出现次数

Question

我正在尝试找到一个 MySQL 查询，该查询将在特定字段中查找 DISTINCT 值，计算该值的出现次数，然后按计数对结果进行排序。

示例数据库

id         name
-----      ------
1          Mark
2          Mike
3          Paul
4          Mike
5          Mike
6          John
7          Mark

预期结果

name       count
-----      -----
Mike       3
Mark       2
Paul       1
John       1

Answer 1

SELECT name,COUNT(*) as count 
FROM tablename 
GROUP BY name 
ORDER BY count DESC;
