How to see specific edge data in GSQLShell?

1

Hi ,

Do we have a way to select and see the edge attributes in GSQLShell like we do for vertices ?

For Eg :
select * from Person where GDPRFlag == false - query gives us the Person vertex attributes . Do we have similar query to get HAS_PERSON_NAME edge attributes ?

Hi @Sneha_S_S ,

You can “collect” the edges and print it out by doing a GSQL query like below:

CREATE OR REPLACE QUERY get_has_person_name_edge_info() FOR GRAPH <your-graph-name> {
    ListAccum<EDGE> @@edge_list;
    all_person = {Person.*};

    all_person = SELECT s
        FROM all_person:s -(HAS_PERSON_NAME:e) - PersonName:t
        WHERE s.GDPRFlag == FALSE
        ACCUM @@edge_list += e;
    
    PRINT @@edge_list AS has_person_name_edges;
}

Note that, in this query, we do a 1-hop query (edge traversal) and utilize the accumulator to gather the edges. After that, we would print out the edges.

If you want some more advanced info, you can check out the docs page, as seen here:

I hope this helps! Please let us know if you have any further questions.
