I want to extract (retrieve) all the nodes and relationships in a graph starting from a specific node.
I have tried something like:
MATCH (n:Resource resource_id: "R208997")
MATCH p=(n)-[*]->(m)
RETURN p
This fetches all the paths from the node I have, but It is not really what I want.
What I want is to have a table showing the following:
From | Rel. | To
----------------
x | r | y
z | r2 | g
I am using version: 3.4.12 Community edition of Neo4J, and the data that I'm working on looks like this:

Best approach is to use APOC Procedures, we have some path expander procs for doing this efficiently.
You can use apoc.path.subgraphAll() for this, YIELDing relationships which you can alias accordingly:
MATCH (n:Resource resource_id: "R208997")
CALL apoc.path.subgraphAll(n, relationshipFilter:'>') YIELD relationships
UNWIND relationships as rel
RETURN startNode(rel) as from, type(rel) as rel, endNode(rel) as to
If you need to output only certain properties from the nodes rather than the node itself, then you can modify that in your RETURN accordingly.
