Question

我有2张这样的表：
[游戏]
游戏ID
hometeamid
awayteamid
得分

和

[小组]
teamid
teamname

如何创建查询以输出如下内容：
[主队] [客场球队] [得分]
49人充电器28-17

你知道，我需要在同一个表中解析2个团队名称和2个团队ID，并输出名称。在此先感谢您的帮助！

Answer 1

SELECT
  ht.TeamName AS HomeTeam,
  vt.TeamName AS AwayTeam,
  g.Score
FROM
  games g INNER JOIN teams ht
    on g.hometeamid = ht.teamid
  INNER JOIN teams vt
    on g.awayteamid = vt.teamid

我建议命名表“游戏”和“团队” - 因为我不是多个表名的粉丝。在这个意见中我并不孤单，但这确实是一种风格/偏好。

Answer 2

这应该适合你：

select t1.teamname, t2.teamname, g.score
from games as g
     left outer join team as home_team
       on g.hometeamid = home_team.id
     left outer join team as away_team
       on g.awayteamid = away_team.id

Answer 3

SELECT (SELECT teams.teamname FROM teams WHERE teams.teamid=games.awayteamid) AS awayteam,     
(SELECT teams.teamname FROM teams WHERE teams.teamid=games.hometeamId) AS hometeam, score 
FROM games 
WHERE gameid = '1'

MYSQL查询多个id以在两个表之间进行名称解析
