【问题标题】：Creating Neo4j relationship while importing from csv从 csv 导入时创建 Neo4j 关系

【问题描述】：

我是 Neo4j 的新手。我有包含格式数据的 csv 文件：

"from","to","amount","count"  
"Lenin","George","10000","1"  
"Mike","Suriya","4000","3"  
"Mike","Norman","10000","1"  
"George","Lenin","4000","1"

现在，我想导入这个带有关系的 csv，这样我就可以得到带有循环重定向的图形，比如列宁和乔治的情况。我该怎么做？

你可以使用

LOAD CSV WITH HEADERS FROM "file:///csv.csv" as row
MERGE (n:Person{name:row.from})
MERGE (m:Person{name:row.to})
MERGE (n)-[r:RELATIONSHIP]->(m)
ON CREATE SET r.amount = row.amount,
              r.count = row.count
