pgr_dijkstra one to many

Question

I´m using pgr_dijkstra one to one and it´s ok, but error occour when I try one to many or many to many. I´m typing:

SELECT * FROM pgr_dijkstra('select id, source ,target, cost from edge',
                           35681, 
                           ARRAY[34450,34926], 
                           FALSE);

The message is:

SQL Error [42883]: ERROR: do not exist the funcion pgr_dijkstra(unknown, integer,integer[],boolean)

May tell me where is the error?

Answer 1

try to use the pgr_bdDijkstra function. This function generates a route from one origin to several destinations.

--Exemple    
SELECT * FROM pgr_bdDijkstra('select id, source ,target, cost from edge',
                           35681, 
                           ARRAY[34450,34926], 
                           FALSE);

I hope it helped you
