小编ser*_*_ka的帖子

我有两张桌子，Results还有Teams

Teams 有以下列：

team_id
team_name

Results 有以下列：

match_id
home_team (foreign key references teams [team_id])
away_team (foreign key references teams [team_id])
score
yellow_cards
red_cards

当我写查询时：

select team_name, score 
FROM teams, results 
WHERE results.home_team = teams.team_id
  AND results.away_team = teams.team_id 

它会给我空集。

我对同一个表中的两个不同列使用相同的外键这一事实是否有问题？
