neo4j-我们可以在具有相同关系类型但具有不同值的相同节点之间创建多重关系吗？

Question

we are trying to achieve something similar- but i just taking a general example below:

1. (A) - [r:ACT_IN {role:'main actor'}]->(m:movie)
2. (A) - [r:ACT_IN {role:'side actor'}]->(m:movie)

Is it possible to create such scenarios? because when i tries to add the second row it doesn't add anything.

Thanks, Pk!

Answer 1

It is certainly possible. You did not provide your exact Cypher queries, so it is not clear where you went wrong.

However, here is a working example (assuming that the DB already contains those Actor and Movie nodes):

MATCH (a:Actor {name: 'Keanu Reeves'}), (m:Movie {title: 'The Matrix'})
CREATE
  (a)-[r1:ACT_IN {role:'main actor'}]->(m),
  (a)-[r2:ACT_IN {role:'side actor'}]->(m);
