In Neo4j to create relationship between nodes you have to use the CREATE statement like we used to create nodes. lets create relation between two already created nodes. Example:
- Already created nodes:
- Query to create relation:
$ MATCH (a:GeeksforGeeks), (b:W3School) WHERE a.Name = "A Computer Science Portal" AND b.Name = "We are the Learner" CREATE (a)-[r:edutech]->(b) RETURN r
- Output of above query:
- Creating a new node:
$ CREATE (c:Company { Name: "Tutorial" })- Output:
- Creating relationship:
MATCH (a:GeeksforGeeks), (b:W3School), (c:Comapny) WHERE a.Tag = "A Computer Science Portal" AND b.Tag = "We are the Learner" AND c.Name = "Tutorial" CREATE (c)-[pr:PRODUCED]->(b), (c)-[pr1:PROVIDER]->(a) RETURN a, b, c
- Output:
