Hi all,
I am trying to install dijkstra module on postgreSQL 8.0 with debian ;
after the execution of assign_vertex_id (which works), I have an error msg launching the create_graph function :
ERREUR: une clé dupliquée rompt la contrainte unique «route500_44_edges_source_key»
CONTEXT: instruction SQL «INSERT INTO route500_44_edges (id, source, target) VALUES (944, '671', '703')»
I don't know where this duplicated key ("clé dupliquée") can come from.
Can anyone help?
Thanks
G.
