I think you wanna see the **relation** for (Node a) -[any
relationship]->(Node b)
To see that **realtion**, you need to seperatly return it in `RETURN` clause.
like below
`SELECT * FROM cypher('matrix', $$ MATCH (a)-[r]->(b) RETURN a, r, b$$) as
(a agtype, r agtype, b agtype);`
- to return the edge(relationship), you might as well to clarify the edge
using any notation or alphbet like `r`
- To return the **relationship** for _Node a_ and _Node b_, you have to
clarify the things that you wanna return seperatly like `RETURN a, r, b`
- and you might as well to clarify the return Nodes / Edges and its Data
type like `as (a agtype, r agtype, b agtype)`
But I think you want to see this **relationship** as a unified thing like
tuple, list, array
It is also simple!
`SELECT * FROM cypher('matrix', $$ MATCH p = (a)-[r]->(b) RETURN p$$) as (p
agtype);`
All you gotta do is you can simply declare the **relationship** to a path
like `MATCH p = (a)-[r]->(b)`
then it is returned **unified value** with list which is a kind of data type
in Cypher like below
`p\nagtype\n[{"id": 1125899906842625, "label": "vt_car", "properties":
{"carline": "ENCLAVE FWD", "mfr_name": "General Motors", "car_division":

"label": "vt_engine", "properties": {"no_cyl": 6, "eng_displ": 3.6::numeric,
