Hot to query using the auto generated id in the apache age graph database.
I want to get to know if it is edge id or a vertex id.
For example i have an id 844424930131970. I know its somewhere within graph. But I don't know if its id for a vertex or an id for edge
It would sort of depend on what you're trying to MATCH on to determine if it is a vertex or an edge. I don't think it is possible to match on an abstract object in the graph.
For a vertex:
postgresDB=# SELECT * FROM cypher('airroutes', $$
MATCH (n)
WHERE id(n) = 844424930131969
RETURN n $$)
AS (n agtype);
n

For an edge:
postgresDB=# SELECT * FROM cypher('airroutes', $$
MATCH ()-[e]-()
WHERE id(e) = 1688849860263937
RETURN e $$)
AS (n agtype);
n
