Path

PATH

PATH is a logical type. Internally, PATH is processed as STRUCT type, more specifically, a STRUCT{LIST[NODE], LIST[REL]}. A PATH always contains a nodes field with key _NODES and a rels field with key _RELS.

Return PATH column

MATCH p = (a:User)-[:Follows]->(b:User)
WHERE a.name = 'Adam' AND b.name = 'Karissa'
RETURN p;

Output:

{_NODES: [{_ID: 0:0, _LABEL: User, name: Adam, age: 30},{_ID: 0:1, _LABEL: User, name: Karissa, age: 40}], _RELS: [(0:0)-{_LABEL: Follows, _ID: 2:0, since: 2020}->(0:1)]}

Access all nodes on a path

MATCH p = (a:User)-[:Follows]->(b:User)
WHERE a.name = 'Adam' AND b.name = 'Karissa'
RETURN nodes(p);

Output:

[{_ID: 0:0, _LABEL: User, name: Adam, age: 30},{_ID: 0:1, _LABEL: User, name: Karissa, age: 40}]

Access all rels on a path

MATCH p = (a:User)-[:Follows]->(b:User)
WHERE a.name = 'Adam' AND b.name = 'Karissa'
RETURN rels(p);

Output:

[(0:0)-{_LABEL: Follows, _ID: 2:0, since: 2020}->(0:1)]
