Question

我已经有一个联赛积分表，但是，我想让它考虑到2平局等于胜利，并且在平局中，最低点优先。

目前显示如下，但技术上Team2应该赢了：

Team    W   L   T   PF  PA  PCT 
—————————————————————————————————
Team1   7   3   0   247 139 0.7000
Team2   6   2   2   220 122 0.6000 
Team3   6   4   0   191 191 0.6000
Team4   4   5   1   167 201 0.4000 
Team5   3   6   1   142 202 0.3000
Team6   2   8   0   193 305 0.2000

这是SQL：

SELECT team
 , COUNT(*)  played
 , SUM(win)  wins
 , SUM(loss) lost
 , SUM(win)/count(*) pctWon
 , SUM(draw) draws
 , SUM(SelfScore) ptsfor
 , SUM(OpponentScore) ptsagainst
 , SUM(SelfScore) - SUM(OpponentScore) goal_diff
 , SUM(3*win + draw) score
FROM (
  SELECT team
 , SelfScore
 , OpponentScore
 , SelfScore > OpponentScore win
 , SelfScore < OpponentScore loss
 , SelfScore = OpponentScore draw
  FROM (
    SELECT HomeTeam team, HomeScore SelfScore, AwayScore OpponentScore
    FROM Game
    union all select AwayTeam, AwayScore, HomeScore
    FROM Game
   ) a
) b
GROUP BY team
ORDER BY wins DESC, draws DESC, lost ASC, goal_diff DESC;

Answer 1

看一下你的ORDER BY条款：你实际上是要求按顺序递减顺序排列结果。这个规则优先于所有其他规则，所以很明显Team1获胜。

ORDER BY wins DESC, draws DESC, lost ASC, goal_diff DESC;

我想让它考虑到2平局等于胜利，并列最低点优先。

那就是：

ORDER BY (wins*2 + draws) DESC, lost ASC, ptsagainst DESC;

Answer 2

从abl的回答中，我将预先存在的, SUM(3*win + draw) score更改为 , SUM((win*2 + draw)- loss) score

然后只需输入ORDER BY score DESC, ptsagainst DESC;

这给出了预期的结果！
