Mysql 足球数据库-sql查询-无视图-进球最多的球队

我的桌子是：

匹配表：

  season
  id_match
  home_team_id
  away_team_id
  home_team_goal
  away_team_goal

及

团队成员表：

  id_team
  name_team

对于每个赛季，我都需要选择得分更多的球队的名字。我是SQL新手，在连接方面仍然存在一些问题（我永远不知道使用哪种类型，如果是左、右、全..）。 这就是我尝试过的：

top_scorer_team = ("""SELECT season, team_id, sum(goals) as goals
    from (select home_team_id as id_team, home_team_goal as goals from match_table
    union all
    select away_team_id as id_team, away_team_goal as goals from match_table)
    group by id_team 
    order by goals desc""")

它不能正常工作。有人能帮忙吗？ 另外，我知道一旦我有了id，我还需要加入团队表来检索团队的名称

编辑： 例如：

id_team | team_name

  ---------+---------------

   10      | A

   20      | B

   30      | C

   40      | D

   50      | E

查询应返回：

season | team_name | total_goals

  ---------+-----------+------------
2008/2009| C     | 3

ecc.

要按团队获得本赛季的所有目标：

select name_team, season, sum(tot_goals) as all_goals
from (
  select t1.name_team, season, g1.home_team_goals + g2.away_team_goals as tot_goals
  from team_table t1
  left join match_table g1
    on t1.id_team = g1.home_team_id
  left join match_table g2
    on t1.id_team= g2.away_team_id
) x1
group by name_team, season

你应该能够从这里获得特定的团队信息

“我永远不知道该使用哪种类型，如果是左、右、全。”-右很少使用，而且在mysql中不存在全（虽然可以模拟它）“它不能正常工作”…？还有

top\u scorer\u team=sqlContext.sql（“…

不是正确的sql（或mysql）语法。“每个季节”-你的表格中没有任何季节的标志？@Luuk我知道我忘了把它排除在问题之外。这是因为我正在与pyspark合作anyways@P.Salmon是的，match_表中有一个名为“季节”的列。它有2008/2009或2015/2016的字段，在最后一行出现错误，如下所示“参考‘季节’不明确，可能是：g1.season，g2.season"@yoyo_24:也可以是

t1.season

…由你决定哪一个是正确的！@Luuk我该怎么做？首先，从你的查询中复制错误消息，并将其添加到你的问题中。其次，安装li。这样你就可以自己测试你的查询了。这篇文章中的查询现在被添加到a中，只是为了给出答案你（和其他人）有一个快速测试东西的方法。

select name_team, season, sum(tot_goals) as all_goals
from (
  select t1.name_team, season, g1.home_team_goals + g2.away_team_goals as tot_goals
  from team_table t1
  left join match_table g1
    on t1.id_team = g1.home_team_id
  left join match_table g2
    on t1.id_team= g2.away_team_id
) x1
group by name_team, season
