I want to copy existing relationships to a new node. All nodes exist already

  • 0

I want to copy existing relationships to a new node. All nodes exist already and I would like to copy all incoming relationships to a second node. Given a node D and a graph like

A -[r]-> B <-[s]- C

I would like to create the following in a single Cypher query:

A -[r]-> B <-[s]- C
A -[r]-> D <-[s]- C

Only the relationships in the second line should be created, as all other nodes exist already. I have tried the following Cypher query (which is an Invalid query (Don't know how to extract parameters from this type: org.neo4j.kernel.impl.core.RelationshipProxy)):

START targetNode = node(42)
MATCH sourceNode -[r]-> targetNode
CREATE sourceNode -[s:TYPE(r)]-> targetNode
RETURN s

    There doesn’t exist any good way to do this today. It’s a very reasonable use case though, so I would encourage you to raise an issue about it here: https://github.com/neo4j/community/issues

    Thanks for sharing!
