cypher query to get all relationship for a node doesn't return graphical representation in 3.1

问题

I upgraded neo4j community edition from 3.0.3 to 3.1 and this query doesn't return graphical representation of all the relationships for this node anymore.

MATCH (:User {username: 'user6'})-[r]-()
RETURN r

Any reasons why it wouldn't work in 3.1?

回答1:

Looks like the browser requires you to return nodes in order to see the graphical view. Just add variables on your start and end nodes and return them.

MATCH (a:User {username: 'user6'})-[r]-(b)
RETURN r, a, b

回答2:

'r' refers to a relationship on its own. To return a graph you need the node(s) as well.

Try

MATCH graph = (a:User {username: 'user6'})-[r]-(b)
RETURN graph
