[pgrouting-users] Edge column in pgr_dijkstra

[Kaja]

Hi,
I am using function pgr_dijkstra from pgrouting on a shape file I have
attached here.
The table from the shape file has following columns: gid, geom, start_id,
end_id, length

When I run the following code:
SELECT seq, id1 AS node, id2 AS edge, cost FROM pgr_dijkstra('
                SELECT gid AS id,
                start_id::integer AS source,
end_id::integer AS target,
length AS cost
FROM wp_norway_network',
                1,100, false, false);
I am getting results with seq, node, edge and cost. But the values for the
edge column has eight digit values which is not listed in my table. Is not
it supposed to be the gid values of my table has to be given in the edge
column?

I have attached the files as well. You can see the screenshot of my tables
here:
