Dear Carto Webusers!
Is there any possibility to integrate something like a "WHERE" clause in
the calculation of a shortest path, e.g.:
SELECT * FROM shortest_path_as_geometry('mytable', source_id, target_id)
WHERE [attribute] != [value];
??
What is the difference between the "shortest_path_as_geometry()" and the
"shortest_path()" function?
When I use the same source_id and target_id, I get two different
results, e.g. 177 and 188 rows??
Thanks in advance and have a nice weekend!
Till
