I would need a query that returns relation between objects:
ob_1 ob_2
1 2
2 3
3 4
4 5
5 6
If I wanted to know how 1 is related to 6 it would return:
1-2-3-4-5-6
If I wanted to know how 3 is related to 1 it would return:
3-2-1
If my example was set up differently even two different possibilites of relations might show up.
Thanks
