Creating Family Tree with Neo4J

Question

I have a set of data for a family tree in Neo4J and am trying to build a Cypher query that produces a JSON data set similar to the following:

{Name:  \"Bob\"         


        

Answer 1

You might also have a look at Rik van Bruggens Blog on his family data:

Regarding your query

You already create a path pattern here: (p:Person)-[:PARENT*1..5]->(c:Person) you can assign it to a variable tree and then operate on that variable, e.g. returning the tree, or nodes(tree) or rels(tree) or operate on that collection in other ways:

MATCH tree = (p:Person)-[:PARENT*1..5]->(c:Person)
WHERE c.FirstName = 'Bob'
RETURN nodes(tree), rels(tree), tree, length(tree),
       [n in nodes(tree) | n.FirstName] as names

See also the cypher reference card: http://neo4j.com/docs/stable/cypher-refcard and the online training http://neo4j.com/online-training to learn more about Cypher.

Don't forget to

create index on :Person(FirstName);
