Question

这是我的SQL语句，我想找到状态为0的所有游戏以及类似key_word或运动名称的团队名称，就像关键词一样。问题是所有显示的游戏都没有状态0。我做错了什么？

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+"'
            "

看起来您只需将OR条件分别括在括号中：

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%')

如何在嵌套的SQL查询中有条件？
