Question

我正在尝试根据下面的表格检索每个团队的时间表，但是我在显示团队名称时遇到了一些麻烦。这是我的表格：

TEAM （TEAM_ID，队名， team_mascot，等）

GAME （game_id， GAME_DATE， game_home_team， game_visitor_team， game_home_score， game_visitor_score， game_complete）

这是我当前的查询。我可以用这个获得团队的id值，但是我需要团队名称，因为id值对我没什么好处。

SELECT game_home_team, game_visitor_team, game_date
FROM game 
INNER JOIN team home ON home.team_id = game_home_team 
INNER JOIN team visitor ON visitor.team_id = game_visitor_team
WHERE game_home_team = ? 
OR game_visitor_team = 6 
ORDER BY game_date ASC;

如何使用此查询检索团队名称，并根据游戏的分数显示W或L等结果？非常感谢提前。

Answer 1

SELECT
   home.team_name AS home_team,
   visitor.team_name AS visitor_team,
   game_date,
   IF(
      game_home_score = game_visitor_score, 
      'Tie', 
      IF(
         game_home_score > game_visitor_score,
         'Hometeam',
         'Visitorteam'
      )
   ) AS Winner
FROM game 
INNER JOIN team home ON home.team_id = game_home_team 
INNER JOIN team visitor ON visitor.team_id = game_visitor_team
WHERE game_home_team = ? 
OR game_visitor_team = 6 
ORDER BY game_date ASC;
