我假设必须考虑连续顺序。但是订单在哪里？我认为，如果一列火车（或任何东西）从伦敦开往巴黎或从巴黎开往伦敦，情况会有所不同。表中有一个订单字段（我没有把它放在这里），但是您不必担心订单，因为我想找到经过相同车站但没有相同车站的路线。如果有人需要sql提琴（我没有时间了）：事实上，这是个好问题。顺序重要吗？换句话说，如果路线1停在A、B、C，路线2停在A、C、B怎么办？这是一场比赛吗？还是他们在铁路线上，所以车站总是按顺序排列？@Beth，不，顺序没关系，不是应该是compB_NumStations=两个站吗？@Beth。这种情况是多余的。如果你有“a=b”和“a=c”，那么后面就是“a=c”。事实上，其中任何两个条件都足以满足相等条件。（也就是说，为了清楚起见，最好将这三个条件都放进去。）在您的交叉路线查询中，'=0或tblRoutes.STOPS=0'不应该是=1和tblRoutes.STOPS=1吗？@Beth 1表示列车在车站停车，0-当它不在车站停车时，据我所知，问题是让根穿过相同的站点，但不要停在它们上面。对不起，看了你的sqlFiddle之后，我想不出你在做什么。最终的结果是R1和R2不应该停在同一个站点，但中途有不同的站点吗？谢谢，伙计，我尝试了你的解决方案，效果很好。谢谢
