所以我正在为一个时间表系统做一个neo4j项目我为数据库创建了所有节点和关系
但是，一旦我尝试创建一个查询，例如某个特定讲师在某个特定时间某某房间获得某个讲座，就不会这样做
这是我用于创建节点和关系的密码文件

一旦我加载它。然后尝试查询其中一个关系 像这样
MATCH p=(n:Lecturers{ Name:"Deidre O'Donovan"})-[r:TEACHES]-
(l:Lesson{ Name:"Lab"})-[:ON]->(d:Days{Name:"Tuesday"})-[:IN]->
(h:Rooms{ Name:"G0482 CR3"}) RETURN p
但它会继续给空白屏幕说（没有变化，没有记录） 任何帮助都非常感激，因为我过去两天一直在这里。
答案 0 :(得分：3)
您的主要问题之一是数据创建查询使用的数据模型与您用于第二个查询的数据模型不同。所以，当然第二个查询与任何内容都不匹配。
您的数据创建查询（仅）有2个Lesson个节点，并且每个关系直接连接到其中一个节点。
在第二个查询中，大多数关系不直接连接到2个Lesson节点。但是该查询的数据模型也存在很大缺陷，因为每个Rooms节点与5个Days节点中的一个节点直接相关，这意味着一旦您遍历到Days节点，您与当天相关的所有Rooms个节点都有关系（适用于所有讲师和课程）。你无法分辨任何讲师用于任何课程的房间。
您的数据创建查询中也存在拼写错误。 ＆＃34; Thursay＆＃34;应该是＆＃34;星期四＆＃34;。
因此，您需要确定可行的数据模型并始终如一地使用它。
