Usage Examples

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

MERGE (person1:Person {name: "Michael"})
MERGE (person2:Person {name: "Ryan"})
MERGE (person3:Person {name: "Jennifer"})

MERGE (person1)-[:FRIENDS]->(person2);

The following makes Jennifer the end node in the FOLLOWS relationship instead of Ryan:

MATCH (:Person {name: "Michael"})-[rel:FRIENDS]->()
MATCH (jennifer:Person {name: "Jennifer"})
CALL apoc.refactor.to(rel, jennifer)
YIELD input, output
RETURN input, output;

If we execute this query, it will result in the following output:

Table 1. Results
input	output
32	[:`FRIENDS`]

And the graph now looks like this:
