Question

I want to fetch all 3rd level nodes(4,5,6 and 7 in below pic) and its relationships along with its parent node details In the below example:

• If I send ID : 7

Answer 1

This is a typical path query. If you link it to both child and root, you only have to retrieve a single path. Below I assume that you pass myid as a parameter and that you have linked the nodes using :HAS_CHILD relationships

// the path pattern
MATCH path=(root)-[:HAS_CHILD*]->(child)  
// limiting the search
WHERE NOT ()-[:HAS_CHILD]->(root)
      AND child.ID = $myid

//returning the results
RETURN path

or 

// return the IDs, except the last one, because it is the node you started from
UNWIND nodes(path)[..-1] AS node
RETURN node.ID AS parent
