獲取來自不同teamId火柴行不是打用戶

Question

所以我想做的事：

我想與敵人冠軍（不同teamId）爲每每一行與ID 42999456起到匹配召喚。

例如：

summonerId：42999456
matchId：2528256239

將返回

+------------+------------+------------+--------+--------+ 
| matchId | summonerId | championId | teamId | winner | 
+------------+------------+------------+--------+--------+ 
| 2528256239 | 23364213 |  412 | 200 |  0 | 
| 2528256239 | 34928637 |  429 | 200 |  0 | 
| 2528256239 | 40909308 |   4 | 200 |  0 | 
| 2528256239 | 50717471 |  122 | 200 |  0 | 
| 2528256239 | 52439549 |   60 | 200 |  0 | 

（請注意，我不希望只查詢1 matchId，我要查詢所有比賽）。

表看起來像這樣：

| matchId | summonerId | championId | teamId | winner | 
+------------+------------+------------+--------+--------+

Answer 1

做這件事的方法是使用NOT EXISTS：

SELECT matchId, summonerId, championId, teamId, winner 
FROM mytable AS t1 
WHERE matchId = 2528256239 AND 
     NOT EXISTS (SELECT 1 
        FROM mytable AS t2 
        WHERE t2.summonerId = 42999456 AND 
         t1.matchId = t2.matchId AND 
         t1.teamId = t2.teamId)

你也可以使用一個LEFT JOIN：

SELECT t1.matchId, t1.summonerId, t1.championId, t1.teamId, t1.winner 
FROM mytable AS t1 
LEFT JOIN mytable AS t2 
    ON t1.matchId = t2.matchId AND t1.teamId = t2.teamId AND t2.summonerId = 42999456 
WHERE t1.matchId = 2528256239 AND t2.matchId IS NULL
