Neo4j 加权交互
Neo4j Weighted Interactions
我有一个很大的 CSV 文件，看起来像
Node1 Node2 Weight
1 2 10
2 3 15
1 3 5
3 10 20
etc...
我想在 Neo4j 上创建一个图表，显示节点 1 和节点 2 之间的交互，按权重列加权。
多亏了这个 post How to create unique nodes and relationships by csv file imported in neo4j?
我创造了互动
但是我还没有配重
我尝试了以下
USING PERIODIC COMMIT 500
LOAD CSV WITH HEADERS FROM "file:///ewqrwqsa.csv" AS line
MERGE (n:A {number : line.Node1})
WITH line, n
MERGE (m:B {ID : line.Node2})
WITH line, m, n
MERGE (l:W {weight : toInteger(line.Weight)})
WITH l,m,n
MERGE (n)-[:Related(l)]->(m);
但是没用...
谢谢！
您似乎在尝试为关系添加 属性。试试这个：
USING PERIODIC COMMIT 500
LOAD CSV WITH HEADERS FROM "file:///ewqrwqsa.csv" AS line
MERGE (n:A {number : line.Node1})
MERGE (m:B {ID : line.Node2})
MERGE (n)-[r:Related]->(m)
SET r.weight = toInteger(line.Weight);
