Usage Examples

The examples in this section are based on the following sample graph:

CREATE (mark:Person {name: "Mark", city: "London"})
CREATE (jennifer:Person {name: "Jennifer", city: "St Louis"})
CREATE (michael:Person {name: "Michael", city: "Dresden"})
CREATE (mark)-[:FOLLOWS]->(jennifer);

The following makes Michael the start node in the FOLLOWS relationship:

MATCH (michael:Person {name: "Michael"})
MATCH ()-[rel:FOLLOWS]->()
CALL apoc.refactor.from(rel, michael)
YIELD input, output
RETURN input, output;

Results
input	output
14	[:FOLLOWS]

We can list all the Person nodes by running the following query:

MATCH path = ()-[rel:FOLLOWS]->()
RETURN path;

Results
path
(:Person {name: "Michael", city: "Dresden"})-[:FOLLOWS]→(:Person {name: "Jennifer", city: "St Louis"})
