如何在嵌套SQL查询中有条件？

Question

这是我的SQL语句，我想查找状态为0的所有游戏以及像key_word一样的团队名称或像关键字一样的运动名称。 问题在于显示的所有游戏的状态都不为0。 我究竟做错了什么？

sql="select * from games where games.status=0 and games.team_2_id
     IN (select id from teams where name like '"+key_word+"')
      or games.team_1_id
        IN (select id from teams where name like '"+key_word+"')
          or games.sport like '"+key_word+"'
            "

Answer 1

看起来您只需要在括号中单独包含OR条件即可：

SELECT * 
FROM   games 
WHERE  games.status = 0 AND 
       (games.team_2_id IN (SELECT id FROM teams WHERE name LIKE '%key_word%') OR
        games.team_1_id IN (SELECT id FROM teams WHERE name LIKE '%key_word%') OR
        games.sport LIKE '%key_word%')
