MySQL的最大值取整行

Question

表 'teams_members'

• TEAM_ID
• USER_ID

表 'users_playeraccounts'

• USER_ID
• Rank_solo
• Summoner_name

表 '用戶'

• 編號
• 用戶名

我的目標：抓取他們的summonername和rank_solo其中rank_solo是最高明的目前所有的團隊成員他們的playeraccounts

因此，'users_playeraccounts'ca中的多個條目n屬於單個用戶。

Select user_id,summoner_name,rank_solo 
    from teams_members t 
     join users_playeraccounts p on t.user_id = p.user_id 
     join users u on u.id = p.user_id 
    where team_id = 103 

的東西加到我沒有的

Answer 1

線索試試這個

select a.username, u.rank_solo, u.summoner_name 
    from teams_members as t 
    inner join users_playeraccounts as u on t.user_id = u.user_id 
    inner join users as a on a.id in (select u.user_id from users_playeraccounts 
              group by u.summoner_name, 
              having max(u.rank_solo));
