Usage Examples
The examples in this section are based on the following sample graph:
CREATE (jennifer:Person {name: "Jennifer", community: 1, partition: 4})
CREATE (karin:Person {name: "Karin", community: 4, partition: 2})
CREATE (elaine:Person {name: "Elaine", community: 3, partition: 3})
MERGE (jennifer)-[:FRIENDS {since: datetime("2019-06-01")}]-(karin)
MERGE (jennifer)-[:FRIENDS {since: datetime("2019-05-04")}]-(elaine);
We can duplicate all relationship properties, by running the following query:
MATCH (:Person)-[friends:FRIENDS]->(:Person)
WITH friends, keys(friends) AS keys
CALL apoc.create.setRelProperties(friends,[k in keys | k + "Copy"], [k in keys | friends[k]])
YIELD rel
RETURN startNode(rel).name AS start, rel, endNode(rel).name AS end;
start | rel | end |
