I want to calculate the shortest way between two points using pgr_dijkstra
function. When I excecute that function, it doesn't show anything. Only when
two points are just in front of each other, pgr_dijkstra shows the way it is
between them. Just in this last case, pgr_dijkstra works fine. But when the
calculation is more complex, pgr_dijkstra does nothing.

I made a lot of tries and I am sure that pgr_createTopology doesn't work as
it should. Maybe my table needs more fields to get its topology done well,
but I donĀ“t know what.

An explanation about what fields are needed for pgr_createTopology would be
helpful too.

I attach two screenshots: how it built the table's topology and its fields

Thank you very much!
