Mysql 选择并计算具有多个相同值的行

Question

我正在尝试创建一个查询，允许我选择如下所示的数据

id  Counter_Type Champion_Name Counter_Lane 
---|------------|------------|--------------
1  | 1          | Ahri       | 1
2  | 1          | Ahri       | 2
5  | 1          | Ahri       | 2
3  | 1          | Ahri       | 3
4  | 1          | Ahri       | 2
6  | 1          | Teemo      | 1
7  | 1          | Warwick    | 4
8  | 1          | Warwick    | 4

它应该对 Counter_Lane 进行计数，然后应该为该名称显示最多的 Counter_Type，如下所示，它应该如何显示数据:

id  Counter_Type Champion_Name Counter_Lane 
---|------------|------------|--------------
1  | 1          | Ahri       | 2
2  | 1          | Teemo      | 1
3  | 1          | Warwick    | 4

我已经尝试了以下代码，这是我三个多小时以来最接近的代码，所以请有人帮忙。

SELECT 
    a.Counter_Type, Champion_For, a.Counter_Lane, a.Champion_Name, COUNT(*) as Amount, sum(vote_type = 'up') as Upvotes, sum(vote_type = 'down') as Downvotes, sum(vote_type = 'up')-sum(vote_type = 'down') as Totalvotes 
FROM Champion_Counters_Data a 
JOIN ( SELECT c.Counter_Lane, c.Champion_Name, COUNT(*) magnitude 
FROM Champion_Counters_Data c 
WHERE 
    Champion_For = "Aatrox" AND Counter_Type = 1 GROUP BY Champion_Name, Counter_Lane ORDER BY magnitude) b ON a.Champion_Name = b.Champion_Name AND b.Counter_Lane = a.Counter_Lane 
GROUP BY Champion_Name

Answer 1

SELECT * FROM your_table  GROUP BY MAX(Counter_Lane)

此查询基于您想要从给定的表中获得的输出。
