我将如何更改此mysql查询以包括另一个mysql表？

Question

之前我问过一个问题，该问题是根据足球结果列表动态创建表格的，我忘了添加，后来意识到是缺少某些东西，基本上我想在输出表格中包括俱乐部徽章。

这是在浏览器中即时生成表的代码

$sqlCommand = " 
    select team, 
    count(*) played,
    count(case when goalsfor > goalsagainst then 1 end) wins, 
    count(case when goalsagainst> goalsfor then 1 end) lost, 
    count(case when goalsfor = goalsagainst then 1 end) draws,
    sum(goalsfor) goalsfor, 
    sum(goalsagainst) goalsagainst, 
    sum(goalsfor) - sum(goalsagainst) goal_diff,
    sum(case when goalsfor > goalsagainst then 3 else 0 end 
        + case when goalsfor = goalsagainst then 1 else 0 end)score 
   from (select hometeam team, homebadge badge, goalsfor, goalsagainst from serie_a_2010_2011
   union all
         select awayteam, awaybadge, goalsagainst, goalsfor from serie_a_2010_2011) a
   group by team
   order by score desc, goal_diff desc";

我在数据库中创建了另一个具有以下结构的表，称为徽章

     ----------------------------------------------
    | id | team    |    badge                      |
     ----------------------------------------------
    |  1 | Inter   | (link to image of Inter badge)|
     ----------------------------------------------
    |  2 | Milan   | (link to image of Milan badge)|
     ----------------------------------------------
etc etc

这包括将在排行榜中输出的所有球队

我将如何创建/添加/加入/额外查询，以为合适的团队输出合适的徽章？

我会说在所选字段列表中添加badges_table.badge （选择后立即添加）

然后在GROUP之前添加LEFT JOIN badges_table ON badges_table.id = tableThatHasBadge.badgeField ，这应该可以帮助您：)

让我知道你是否还有顾虑
