How to create edges based on the equality check on vertex attributes in Cypher?

For example: lets say I have one object like this

Employees {name: "abc, country: "NZ"}

and lets say I have the following objects

Manager { name: "abc", depatment: "product"}

Manager {name: "abc", depatment: "sales"}

Manager {name: "abc", depatment: "marketing"}

Now I want to create all the edges where Employees.name = Manager.name

How do I write the Cypher query to create all 4 vertices and 3 edges?

回答1:

Find the pairs first with MATCH clause and then CREATE a relationship between them.

MATCH (e:Employees),(m:Manager)
WHERE e.name=m.name
WITH e,m
CREATE (m)-[:REL_NAME]->(e)
