Neo4j Create Relationship
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:
To create multiple relationship between nodes:
You can see how easy it is to continue creating more nodes and relationships between them. So we will create one more node and add two more relationships. - Creating a new node:
$ CREATE (c:Company { Name: "Tuitorial" })
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 = "Tuitorial" CREATE (c)-[pr:PRODUCED]->(b), (c)-[pr1:PROVIDER]->(a) RETURN a, b, c
Output:
