Comments - OQGRAPH Examples

In I have two or more paths between a couple of nodes in my graph, and I want to give priority to a specific path even if it crosses more nodes than the others, is it possible to set a value in the 'weight' field in the oq_backing table to give such priority? If yes, priority is obtained by assigning lower or higher values of 'weight'?

Is it possible to query the previous node for the sequence?

SELECT * FROM oq_graph g
WHERE g.latch='dijkstras' AND g.origid=1;

Actual result:

latch	origid	destid	weight	seq	linkid
dijkstras	1	NULL	4	6	5
dijkstras	1	NULL	3	5	4
dijkstras	1	NULL	2	4	6
dijkstras	1	NULL	2	3	3
dijkstras	1	NULL	1	2	2
dijkstras	1	NULL	0	1	1

Expected result:

latch	origid	destid	weight	seq	linkid	prev
dijkstras	1	NULL	4	6	5	4
dijkstras	1	NULL	3	5	4	3
dijkstras	1	NULL	2	4	6	2
dijkstras	1	NULL	2	3	3	2
dijkstras	1	NULL	1	2	2	1
dijkstras	1	NULL	0	1	1	NULL
