Path Functions

Example Graph

The following examples run against this graph:

path_length()

Returns the number of edges in a path.

GQL
MATCH p = ()->{1,3}()
RETURN p, PATH_LENGTH(p) AS length

Result:

pedges()

Collects edges in a path into a list.

GQL
MATCH p = ({_id: "P1"})-[]->{1,2}()
RETURN pedges(p)

Result:

pedgeUuids()

Collects the _uuid values of edges in a path into a list.

GQL
MATCH p = ({_id: "P1"})-[]->{1,2}()
RETURN pedgeUuids(p)

Result:

pnodes()

Collects nodes in a path into a list.

GQL
MATCH p = ({_id: "P1"})-[]->{1,2}()
RETURN pnodes(p)

Result:

pnodeIds()

Collects the _id values of nodes in a path into a list.

GQL
MATCH p = ({_id: "P1"})-[]->{1,2}()
RETURN pnodeIds(p)

Result:
