Neo4j关系节点笔记

1. 导入关系点

load csv from 'file:///M1-CVE-2015-5122_windows_h1_edge_edge_bind_no_header.csv' as line
create (:bind {source:line[0],target:line[1],parentGraph:'M1',sonGraph:'h1'})

注：若关系之间的source或者target点不存在时，先导入节点，如

load csv from 'file:///M1-CVE-2015-5122_windows_h1_edge_edge_connected_session_no_header.csv' as line
create (:process {name:line[0],parentGraph:'M1',sonGraph:'h1'})

导入完节点以后，需要进行去重操作，删除重复节点

MATCH (p:process {parentGraph:'M1',sonGraph:'h1'})
WITH p.name AS name, collect(p) AS nodes
WHERE size(nodes) > 1
FOREACH (node IN tail(nodes) | DELETE node)

2. 创建关系

MATCH (n:session {parentGraph:'M1',sonGraph:'h1'}),(m:bind {parentGraph:'M1',sonGraph:'h1'}),(s:process{parentGraph:'M1',sonGraph:'h1'}) 
where n.name=m.source and m.target=s.name 
create (n)-[r:bind]->(s)

3. 删除关系点

这是中间文件，不需要保存

MATCH (n:bind)
DETACH DELETE n

4. 添加边的属性

LOAD CSV FROM 'file:///M1-CVE-2015-5122_windows_h1_edge_edge_bind_no_header.csv' AS line
MATCH (session {name: line[0]})-[r]->(process {name: line[1]})
SET r.capacity = line[2],r.ip = line[3],r.key= line[4],r.label = line[5],r.port = line[6]  ,r.timestamp = line[7]
return r,session,process

5. 查询关系

LOAD CSV FROM 'file:///M1-CVE-2015-5122_windows_h1_edge_edge_bind_no_header.csv' AS line
MATCH (session {name: line[0]})-[r]->(process {name: line[1]})
return r,session,process

6. 删除关系

MATCH ()-[r:bind]->()
DELETE r

7. 补充

需要导入的csv放在neo4j的import目录下就是默认的file目录
