Neo4j: Combine relationship types using |

You can ask the queries like ‘give me the nodes that has either of given relationship using | (OR) operator’.

 

Let’s see it with an example.

 

Step 1: Open neo4j browser by hitting following url in browser.

http://localhost:7474/browser/

 

 

Step 2: Insert data by executing below query.

CREATE (p1:Person{name: "Rama Krishna", age: 32, city: "Bangalore", male: true, designation: "CEO"}),
(p2:Person{name: "Murali", age: 32, city: "Hyderabad", male: true, designation: "Vice President"}),
(p3:Person{name: "Gopi", age: 34, city: "Chennai", male: true, designation: "Vice President"}),
(p4:Person{name: "Kiran", age: 28, city: "Bangalore", male: true, designation: "Director"}),
(p5:Person{name: "Siva", age: 45, city: "Hyderabad", male: true, designation: "Director"}),
(p6:Person{name: "Kiran", age: 36, city: "Hyderabad", male: true, designation: "Manager"}),
(p7:Person{name: "Ritweek", age: 23, city: "Bangalore", male: true, designation: "Manager"}),
(p8:Person{name: "Sudheer", age: 24, city: "Chennai", male: true, designation: "Manager"}),
(p9:Person{name: "Naveen", age: 37, city: "Bangalore", male: true, designation: "Employee"}),
(p10:Person{name: "Sailaja", age: 31, city: "Hyderabad", female: true, designation: "Employee"}),
(p11:Person{name: "Harika", age: 36, city: "Bangalore", female: true, designation: "Employee"}),
(p12:Person{name: "Brahmam", age: 41, city: "Bangalore", male: true, designation: "Employee"}),
(office1:Location{name: "Pluto", city: "Bangalore"}),
(office2:Location{name: "Mars", city: "Chennai"})
MERGE (p2)-[:REPORT_TO{from: 2014}]->(p1)
MERGE (p3)-[:REPORT_TO{from: 2016}]->(p1)
MERGE (p4)-[:REPORT_TO{from: 1997}]->(p2)
MERGE (p5)-[:REPORT_TO{from: 1997}]->(p3)
MERGE (p6)-[:REPORT_TO{from: 2001}]->(p4)
MERGE (p7)-[:REPORT_TO{from: 2009}]->(p4)
MERGE (p8)-[:REPORT_TO{from: 1998}]->(p5)
MERGE (p9)-[:REPORT_TO{from: 2003}]->(p6)
MERGE (p10)-[:REPORT_TO{from: 2004}]->(p6)
MERGE (p11)-[:REPORT_TO{from: 2008}]->(p7)
MERGE (p12)-[:REPORT_TO{from: 2019}]->(p8)
MERGE (p2)-[:FRIEND_TO{from: 2014}]->(p1)
MERGE (p10)-[:FRIEND_TO{from: 2014}]->(p8)
MERGE (p7)-[:FRIEND_TO{from: 2014}]->(p9)
MERGE (p3)-[:RELATIVE_TO{from: 2014}]->(p4)
RETURN p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, office1, office2

Step 3: Execute below query to get all the nodes who are either in FRIEND_TO or RELATIVE_TO relationship.

 

MATCH (n1)-[rel:RELATIVE_TO | FRIEND_TO]->(n2) RETURN n1, n2, rel

Above statement matches the nodes if there is any relationship RELATIVE_TO or FRIEND_TO between nodes from n1 to n2.

Get the nodes who are either friend or relative to a person

MATCH (n1)-[rel:RELATIVE_TO | FRIEND_TO]->(n2) RETURN n1
