但我该如何分配赢家、平局或输家呢？然后计算得分和对手得分？首先将得分表合并在一起，将主队与awayteam交换，并交换进球数。这将为您提供一些易于聚合的源数据，生成记分卡的查询如下所示：
select
team,
count(*) played,
count(case when goalsfor > goalsagainst then 1 end) wins,
count(case when goalsagainst> goalsfor then 1 end) lost,
count(case when goalsfor = goalsagainst then 1 end) draws,
sum(goalsfor) goalsfor,
sum(goalsagainst) goalsagainst,
sum(goalsfor) - sum(goalsagainst) goal_diff,
sum(
case when goalsfor > goalsagainst then 3 else 0 end
+ case when goalsfor = goalsagainst then 1 else 0 end
) score
from (
select hometeam team, goalsfor, goalsagainst from scores
union all
select awayteam, goalsagainst, goalsfor from scores
) a
group by team
order by score desc, goal_diff desc;
//连接内容

}
