MySQL查询/体育表+时间表中的错误

Question

我的目的是根据我的日程安排创建排名，其中包含过去3个比赛日的结果。我有两张桌子，一张包含有关我的运动队的信息，另一张包含时间表。

现在我正在寻找一种方法将比赛结果列入积分榜。到目前为止一切正常，但我的查询没有正确计算第3个比赛日。第3场比赛日在每场比赛中均以1比1战平。

统计：

Team#1  3 Matches, 2 Wins, 0 Draws, 0 Losses
Team#2  3 Matches, 2 Wins, 0 Draws, 0 Losses

等

MySQL表“团队”：

MySQL表“competition_schedule”：

查询：
