未与 Gene Hackman 合作但曾与 Gene Hackman 电影导演合作的演员的 Cypher 查询答案

【问题标题】：Cypher query for actors who have not worked with Gene Hackman but have worked with a Director of a Gene Hackman movie未与 Gene Hackman 合作但曾与 Gene Hackman 电影导演合作的演员的 Cypher 查询
【发布时间】：2021-12-30 03:27:19
【问题描述】：

在我目前正在做的 Person,Movie 的 Neo4j 样本数据集中查找 Gene Hackman 电影的导演：

MATCH
  (p1:Person{name:"Gene Hackman"})-[:ACTED_IN]->(m:Movie)<-[:DIRECTED]-(p2:Person)
RETURN p1, m, p2

我如何找到由 Gene Hackman 电影的导演执导但没有在电影中与 Gene Hackman 一起表演的演员？

这里是一些示例 json 数据，或者更简单的是在 https://sandbox.neo4j.com/ 处选择“电影”数据集

【解决方案1】：

这应该可行。下次如果可以的话，请附上一个小样本数据集。

MATCH (p1:Person {name:"Gene Hackman"})-[:ACTED_IN]->(m:Movie)<-[:DIRECTED]-(director:Person)-[:DIRECTED]->(m2:Movie) 
WHERE NOT (m2)<-[:ACTED_IN]-(:Person {name: "Gene Hackman"}) 
MATCH (m2)<-[:ACTED_IN]-(p4:Person) 
RETURN p4

谢谢 - 对于这些问题，在 Neo4j 中附加示例数据的最佳方法是什么？
用于添加数据的示例密码查询非常适合快速获得帮助。
查询不起作用。让我添加一些示例数据。
@David542 该查询有一个单字符拼写错误，所以不允许我编辑（因为它必须是 6 个字符）。引用 m2 应该是节点标签 Movie，而不是 movie。
@richard -- 可能会添加评论或缩进，或者做一些不难解决的事情！
