How do you create self-referential nodes?

问题

... or is it possible at all to create a node in Neo4j which has a relationship with itself (a simple loop-node)?

If so, what would be the corresponding Cypher query?

回答1:

The following query creates Peter who voted for himself.

MERGE (peter:User { name: "Peter" })
MERGE (peter)<-[:VOTED_FOR]-(peter)
RETURN peter
