从csv导入时创建Neo4j关系

Question

我是Neo4j的新手。我有包含以下格式的数据的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，我想用关系导入这个csv，这样我就可以获得像列宁和乔治那样的循环重定向图。我该怎么做？

Answer 1

您可以使用

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
