問題描述

我想查詢一列，並在第一個player_id列中顯示計數大於9的所有記錄。 只要第一列中的玩家玩過9次以上的玩家。 對手可以是任何人，只要大於9次即可。

這是我首先嘗試的。 

SELECT p1.player_id, p2.player_id, 
     m.date, m.scoreA, m.scoreB, mem1.player, mem2.player, team1.name, team2.name
FROM matches m
LEFT
JOIN `members` mem1
  ON mem1.player      = m.playerA
 AND mem1.start_date <= m.date
 AND ( mem1.end_date >  m.date OR mem1.end_date IS NULL )
LEFT
JOIN `members` mem2
  ON mem2.player      = m.playerB
 AND mem2.start_date <= m.date
 AND ( mem2.end_date >  m.date OR mem2.end_date IS NULL )
JOIN players p1 ON p1.player_id = m.playerA
JOIN players p2 ON p2.player_id = m.playerB
JOIN teams team1 ON team1.team_id = mem1.team
JOIN teams team2 ON team2.team_id = mem2.team
where team2.name = "Prime" and team1.name = "FXOpen e-Sports Korea"
Group By p1.player_id
having count(p1.player_id) > 9
order by p1.player_id, p2.player_id, m.date;

這只給了兩個記錄。 兩條計數大於9的記錄。我想在第一個player_id列中查看計數大於9的所有記錄。 只要第一列中的玩家玩過9次以上的玩家。 對手可以是任何人，只要大於9次即可。

然后我嘗試了這個。 我認為在查詢中執行查詢會起作用。 

SELECT p1.player_id, p2.player_id, 
     m.date, m.scoreA, m.scoreB, mem1.player, mem2.player, team1.name, team2.name
FROM matches m
LEFT
JOIN `members` mem1
  ON mem1.player      = m.playerA
 AND mem1.start_date <= m.date
 AND ( mem1.end_date >  m.date OR mem1.end_date IS NULL )
LEFT
JOIN `members` mem2
  ON mem2.player      = m.playerB
 AND mem2.start_date <= m.date
 AND ( mem2.end_date >  m.date OR mem2.end_date IS NULL )
JOIN players p1 ON p1.player_id = m.playerA
JOIN players p2 ON p2.player_id = m.playerB
JOIN teams team1 ON team1.team_id = mem1.team
JOIN teams team2 ON team2.team_id = mem2.team
where team2.name = "Prime" and team1.name = "FXOpen e-Sports Korea" and
p1.player_id in( select p1.player_id from players p1
                 Group By p1.player_id
                 having count(p1.player_id) > 9
               )
order by p1.player_id, p2.player_id, m.date;

不幸的是，這只是一個空的設置。

這就是我的數據不計其數的樣子。

使用inner join聯接和子查詢在第一個playerA列中計數大於9 

SELECT p1.player_id, p1.real_name, p2.player_id, p2.real_name, 
     m.scoreA, m.scoreB, mem1.player, mem2.player
FROM matches m
INNER JOIN (
    select playerA
    from matches
    group by playerA
    having count(*) > 9
    ) c9 on m.playerA = c9.playerA
JOIN players p1 ON p1.player_id = m.playerA
JOIN members mem1 ON mem1.player = p1.player_id
JOIN players p2 ON p2.player_id = m.playerB
JOIN members mem2 ON mem2.player = p2.player_id
;

或使用IN()和子查詢 

SELECT p1.player_id, p1.real_name, p2.player_id, p2.real_name, 
     m.scoreA, m.scoreB, mem1.player, mem2.player
FROM matches m
JOIN players p1 ON p1.player_id = m.playerA
JOIN members mem1 ON mem1.player = p1.player_id
JOIN players p2 ON p2.player_id = m.playerB
JOIN members mem2 ON mem2.player = p2.player_id
WHERE m.playerA IN (
    select playerA
    from matches
    group by playerA
    having count(*) > 9
    )
;
