I'm begginer on neo4j
I have a data csv person list likes from on file
id,name,parentid
01, John, null,
02, Mark, 01
03, Elina, 01
I try to use apoc lib to load this data
CALL apoc.import.csv(.....) yield value
UNWIND value as v
MERGE(p:Person{id:v.id, name:v.name})
I don't know how to make the relation between them.
Can someone help me?
There is really a LOT of examples using LOAD CSV with Neo4j, starting from the manual : https://neo4j.com/developer/guide-import-csv/.
Really no need for APOC.
LOAD CSV WITH HEADERS FROM "file:///..." AS row
MERGE (p:Person {id: row.id}) SET p.name = row.name
WITH p, row.parent AS parent
WHERE NOT parent IS NULL AND parent <> "null"
MERGE (parent:Person {id: parent})
MERGE (p)-[:LIKES]->(parent)
