Mysql體育聯盟表

Question

我正在創建一個體育網頁，我已經達到了我無法解決自己的問題。

我的問題是，我不知道如何在每個比賽日之後分別存儲每個球隊的位置。以下是我想要實現：

爲了創建排名表我有兩個表：

俱樂部：id_clubs，名
結果：matchid，比賽日，hometeam，awayteam，homegoals， awaygoals，日期，id_league

結果表中創建我的排名表是設置這樣的：

SELECT 
    name AS Team, 
    Sum(P) AS P, 
    Sum(W) AS W, 
    Sum(D) AS D, 
    Sum(L) AS L, 
    SUM(F) as F, 
    SUM(A) AS A, 
    SUM(GD) AS GD, 
    SUM(Pts) AS Pts 
FROM ( 
    SELECT *, 
     hometeamid Team, 
     1 P, 
     IF(homegoal > awaygoal,1,0) W, 
     IF(homegoal = awaygoal,1,0) D, 
     IF(homegoal < awaygoal,1,0) L, 
     homegoal F, 
     awaygoal A, 
     homegoal-awaygoal GD, 
     CASE WHEN homegoal > awaygoal THEN 3 
      WHEN hometeam = awaygoal THEN 1 
      ELSE 0 
     END PTS 
    FROM results 
    WHERE id_league = '$leagueid' 
     AND homegoal IS NOT NULL 
     AND awaygoal IS NOT NULL 

    UNION ALL 

    SELECT *, 
     awayteamid, 
     1, 
     IF(homegoal < awaygoal,1,0), 
     IF(homegoal = awaygoal,1,0), 
     IF(homegoal > awaygoal,1,0), 
     awaygoal, 
     homegoal, 
     awaygoal-homegoal GD, 
     CASE WHEN homegoal < awaygoal THEN 3 
      WHEN homegoal = awaygoal THEN 1 
      ELSE 0 
     END 
     FROM results 
     WHERE id_league = '$leagueid' 
      AND awaygoal IS NOT NULL 
      AND homegoal IS NOT NULL 
) AS tot 
JOIN clubs t ON tot.Team=t.id_clubs 
GROUP BY Team 
ORDER BY 
    SUM(Pts) desc, 
    SUM(GD) desc 

希望有人可以提供一些提示或解決方案。

如果您對您造成表中檢索順序號的問題，這裏是一個類似的討論，這可能是您需要的東西：MySQL - Get row number on select

要選擇第一n比賽中，你可以通過匹配ID分組後做LIMIT n 。
