Question

下午，

我为我所在的团队创建了排名表。

详细信息是从“游戏”数据库中提取的，该数据库记录了所有比赛，日期，主场/客场得分和赛季，然后动态创建表格。

最近，抢劫犯已更改为：

赢/输/绑记录
常规赛（当两支球队在同一条W / L / T记录中并列时）的面对面得分差异
参与游戏的最低平均分（不包括获奖游戏）

我正在努力地思考如何分组/订购以符合这些条件。

表模式（GameId是每个球队名称的前3个字符的组合，主队例如底特律vs芝加哥将是DETCHI，然后是客队CHIDET）：

GameId varchar(10)
GameDate date NULL
GameHomeTeam varchar(100) NULL
GameHomeScore int(4) NULL 
GameAwayTeam varchar(100) NULL
GameAwayScore int(4) NULL
GameSeason int(4)

我的查询

global $wpdb;
$year = "2018";
$query ="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 `GameHomeTeam` team, 
                   `GameHomeScore` SelfScore, 
                   `GameAwayScore` OpponentScore
            FROM Game 
            WHERE `GameSeason` = '" . $year . "' 
            UNION ALL  
            SELECT `GameAwayTeam`, 
                   `GameAwayScore`, 
                   `GameHomeScore`
            FROM Game
            WHERE `GameSeason` = '" . $year . "'
   ) a
) b
GROUP BY team
ORDER BY wins DESC, draws DESC, lost ASC, goal_diff DESC";

非常感谢任何帮助。
