Can some one help me to find the most connected node of particular relationship type in neo4j using cypher query.
Suppose I have
Node1 Node2 Relationship
A B follows
A C follows
B D follows
Here Node D is the most connected node.of particular relationship type "Follows" .so how to find this node using cypher query?
Thanks in Advance
(Edit):
i found my answer tnx Martin Preusse
MATCH (n)<-[r:FOLLOWS]-()
RETURN n, count(r) AS num
ORDER BY num desc
In other words, you want a relationship that connects more than two nodes. Mathematics allows this, with the concept of a hyperedge. This is impossible in Neo4j.
When you want to return all nodes, relationships and paths found in a query, you can use the * symbol. This returns the two nodes, the relationship and the path used in the query.
Relationships. Relationships organize the nodes by connecting them. A relationship connects two nodes — a start node and an end node. Just like nodes, relationships can have properties.
Try this if the direction of the relationship matters (will only return A
and B
):
MATCH (n)-[r:follows]->()
RETURN n, count(r) AS num
ORDER BY num
Or this if you don't need the direction (i.e. the node D
will be returned as well):
MATCH (n)-[r:follows]-()
RETURN n, count(DISTINCT r) AS num
ORDER BY num
