试图为保龄球俱乐部制作一个平均名单

我正在努力为保龄球俱乐部制作一份平均名单。我有一个包含以下表格的数据库：

  • team_medlem (medlem_id, name, address, etc)
  • team_samling (match_id, lag_id, borta (0 = home game, 1 = away game), date, time, etc)
  • team_match (id, match_id, s1, s2, etc)
  • team_resultat (id, medlem_id, results, series, banp, match_id)

我希望得到总平均值，平均值和平均值。结果是每个玩家的整个游戏的总积分，系列是播放系列的数量。 我有这个：

SELECT team_resultat.medlem_id, team_medlem.namn, sum(resultat)/sum(serier) as snitt, sum(banp)
FROM team_resultat 
JOIN team_medlem ON team_resultat.medlem_id = team_medlem.medlem_id 
JOIN team_samling ON team_resultat.match_id = team_samling.match_id
WHERE datum >= current_date - interval '1' year
GROUP BY namn
ORDER BY snitt desc

我怎样才能获得平均值和平均值？

我试过这个，但它计算错误的平均值

SELECT team_resultat.medlem_id, team_medlem.namn, sum(resultat)/sum(serier) as snitt, sum(banp), avg(case when not borta then resultat/serier end) as hemmasnitt, avg(case when borta then   resultat/serier end) as bortasnitt
FROM team_resultat 
JOIN team_medlem ON team_resultat.medlem_id = team_medlem.medlem_id 
JOIN team_samling ON team_resultat.match_id = team_samling.match_id
WHERE datum >= current_date - interval '1' year
GROUP BY namn
ORDER BY snitt desc
