我正在尝试按照＆＃34;使用加载CSV＆＃34导入中的说明学习如何在Neo4j中导入csv文件; LearningNeo4j书的一章。代码我实现了以下内容：
match (n)-[r1 {type:"MOTHER_OF"}]->(m), (s)-[r2 {type:"FATHER_OF"}]->(t)
create n-[:MOTHER_OF]->m, s-[:FATHER_OF]->t
return *;
match ()-[r:REL]-() delete r;
到目前为止一切正常但是当我尝试以这种方式建立关系时：
nodes.csv
Node,Name,Label
1,Amada Emory,Female
2,Rana Seely,Female
3,Detra Thatcher,Female
4,Melda Reza,Female
5,Shana Willems,Female

7,Dagny Agee,Female
8,Tisa Woodman,Female

我无法匹敌。我只是简单地复制并通过了本书的代码，但我无法建立关系。有人可以帮助我吗？
P.S。 csv文件是：
{{1}}

我只是复制你的代码，我获得了以下内容 the precedence of these operators
对不起，但是在你的链接中，我无法理解你是否正在做什么。
答案 0 :(得分：1)
未创建关系上的type属性。所以你的比赛不会结束。
这是因为在您的标头中，Relationship列后面有一个空格，您需要使用空格反复添加列名：
rels.`Relationship `
-
load csv with headers from
"file:C:/wamp/www/fantapappa/rels.csv"
as rels
match (from {id:rels.From}), (to {id: rels.To})
create from-[:REL {type: rels.`Relationship `}]->to
return from, to
另外，我建议您检查标签和索引是什么，以加快插入更大的数据集。

我已将您的csv上传到一个要点，并在此处使用Neo4j控制台运行整个过程http://console.neo4j.org/r/hrao50：
LOAD CSV WITH HEADERS FROM "https://gist.githubusercontent.com/ikwattro/2a38a2f71a7ebc8a6681/raw/da5b47ceab9a9d93f62a12ee1fe8224788c0d861/nodes.csv"
AS nodes
create (n {id: nodes.Node, name: nodes.Name, type: nodes.Label})
return n
LOAD CSV
WITH HEADERS FROM "https://gist.githubusercontent.com/ikwattro/2a38a2f71a7ebc8a6681/raw/da5b47ceab9a9d93f62a12ee1fe8224788c0d861/rels.csv"
AS rels
match (from {id:rels.From}), (to {id: rels.To})
create from-[:REL {type: rels.`Relationship `}]->to
return from, to
MATCH (m { type:"Male" }),(f { type:"Female" })
SET m:Male, f:Female
RETURN m,f
match (n)-[r1 {type:"MOTHER_OF"}]->(m), (s)-[r2 {type:"FATHER_OF"}]->(t)
create n-[:MOTHER_OF]->m, s-[:FATHER_OF]->t
return *;
图表似乎是正确创建的。您能否使用有关灰色图表的屏幕截图更新您的问题。
另请注意，您可能需要通过在浏览器控制台编辑器中发出:style reset命令来重置图表的样式。
