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: 👁 Image
- 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: 👁 Image
- Creating a new node:
$ CREATE (c:Company { Name: "Tutorial" })- Output: 👁 Image
- 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
