Question

我需要帮助制作一个梯子。

见下信息：

表：

cricket_teams(id, name)
cricket_matches(id, hometeam, awayteam, format, season, winner)
cricket_teamperformance(id, matchid, team, innings, score)

（表中还有其他字段对此查询不必要）

我需要得到它，以便它给我胜利，抽奖（胜利者= 0），失败， FIP （当团队在第一次得分更多时）局）， BP （在这种情况下只是获胜）和积分（以粗体显示）。我有一个查询，但我有一些问题。我无法弄清楚如何获得平局和失利，而且也没有让球队没有赢得比赛。这就是我所拥有的：

SELECT b.team, 
       b.name, 
       COUNT(c.wins) as W, 
       count(b.name)*2 as FIP, 
       COUNT(c.wins)*2 as BP, 
       COUNT(c.wins)*4+(count(b.name)*2)+(COUNT(c.wins)*2) as Pts
FROM (SELECT a.name, a.score, a.matchid, a.team
      FROM (SELECT cricket_teams.name, score, matchid, team
            FROM `cricket_teamperformance` 
            LEFT JOIN cricket_teams 
                   ON cricket_teamperformance.team = cricket_teams.id
            INNER JOIN cricket_matches 
                   ON cricket_teamperformance.matchid = cricket_matches.id
            WHERE cricket_matches.format=3
              AND cricket_teamperformance.innings = 1
              AND cricket_matches.season = 1
               OR cricket_matches.format=3
              AND cricket_teamperformance.innings = 2
              AND cricket_matches.season = 1
            ORDER BY matchid, score DESC) as a
      GROUP BY matchid) as b, 
     (SELECT COUNT(winner) as wins, cricket_teams.name
      FROM cricket_matches
      LEFT JOIN cricket_teams ON cricket_matches.winner = cricket_teams.id
      WHERE format = 3
      AND season = 1) as c
GROUP BY b.name
ORDER BY Pts DESC

然后返回：

team    name    W   FIP BP  Pts
4   Chargers    2   4   4   16
2   Hawks       1   2   2   8
1   Ninjas      1   2   2   8

它需要看起来像这样（P是比赛，D是平局，L是亏损）：

team    name    P   W   D   L   FIP BP  Pts
4   Chargers    2   2   0   0   4   4   16
2   Hawks       2   1   0   1   2   2   8
1   Ninjas      2   1   0   1   2   2   8
3   Wolves      2   0   0   2   0   0   0

还有另一支球队，狼队，他们两场比赛都没有赢过。我还需要检索那些抽奖和损失。提前致谢

Answer 1

我发现问题描述和表格架构非常混乱，但这可能会以某种方式帮助您：

SELECT  ct.id AS TeamID,
        ct.name AS TeamName,
        COUNT(DISTINCT cm.id) AS MatchesPlayed,
        COUNT(DISTINCT CASE WHEN cm.winner = ct.id THEN cm.id END) AS Wins,
        COUNT(DISTINCT CASE WHEN cm.winner = 0 THEN cm.id END) AS Draws,
        COUNT(DISTINCT CASE WHEN cm.winner != 0 AND cm.winner != ct.id THEN cm.id END) AS Losses,
        COUNT(DISTINCT
              CASE
                WHEN (ctph.innings = 1 OR ctpa.innings = 1) 
                      AND (ctph.team = ct.id AND ctph.score > ctpa.score)
                THEN ctph.matchid
                WHEN (ctph.innings = 1 OR ctpa.innings = 1) 
                      AND (ctpa.team = ct.id AND ctpa.score > ctph.score)
                THEN ctpa.matchid
              END) AS FIP
FROM    cricket_teams AS ct
        LEFT JOIN cricket_matches AS cm ON cm.hometeam = ct.id OR cm.awayteam = ct.id
        LEFT JOIN cricket_teamperformance AS ctph ON ctph.team = cm.hometeam AND ctph.matchid = cm.id
        LEFT JOIN cricket_teamperformance AS ctpa ON ctpa.team = cm.awayteam AND ctpa.matchid = cm.id
GROUP BY ct.id, ct.name

这是另一种解决方案：

SELECT team,
       name,
       count(*)   AS p,
       sum(win)   AS w,
       sum(draw)  AS d,
       sum(loss)  AS l,
       sum(fi)*2  AS fip,
       sum(win)*2 AS bp,
       sum(win)*4 + sum(fi)*2 + sum(win)*2 AS pts
FROM
  (SELECT t.id AS team,
          t.name,
          m.winner = t.id AS win,
          m.winner = 0    AS draw,
          m.winner <> t.id AND m.winner <> 0 as loss,
          CASE
              WHEN p1.score > p2.score THEN p1.team = t.id
              ELSE p2.team = t.id
          END AS fi
   FROM cricket_matches m,
        cricket_teamperformance p1,
        cricket_teamperformance p2,
        cricket_teams t
   WHERE m.id = p1.matchid
     AND m.id = p2.matchid
     AND p1.innings = 1
     AND p2.innings = 2
     AND (t.id = m.hometeam
          OR t.id = m.awayteam)
     AND m.season = 1
     AND m.format = 3) tallies
GROUP BY team
ORDER BY pts DESC, name
