Question

我使用py2neo

运行此查询

 myQuery = "MATCH p=(:Task {activity: 'Start'})-[:RELATIONSHIP*]->(:Task {activity: 'Finish'}) "\
       "WITH p, REDUCE(x=0, a IN NODES(p) | x + a.duration) AS cum_duration ORDER BY cum_duration DESC "\
       "LIMIT 1 RETURN p AS CritPath WITH p, REDUCE(x=0, a IN NODES(p) | x + a.durata) AS cum_duration ORDER BY cum_duration DESC LIMIT 1 "\
       "RETURN p AS CritPath"


myGraph.run(myQuery).dump()

但它打印

(cd885ed)-[:RELATIONSHIP]->(a94c38f)

如果我想打印＆＃34;活动的名称＆＃34;而不是内存地址＆＃34; cd885ed＆＃34; （比如上面的例子），我该怎么做？

例如：

(start)-[:RELATIONSHIP]->(finish)

非常感谢

任何myGraph.run（）命令都会返回一个光标，其中包含您可以处理的结果。由于您返回的路径是您必须处理的，如果您只需要活动属性，为什么不返回那些？

无论如何......

theCursor = myGraph.run(myQuery)
for theRecord in theCursor:
    # do something with the theRecord

希望这有帮助。
