[pgrouting-users] Problem with query

[Worth Lutz]

Hi Steve,

That method gives the expected results running in psql on the command line.

In pgAdmin, I got the previous results with no values in the id2 column.

I can get the missing id2 with SELECT pgr_bdDijkstra(..) on pgAdmin also.

Confusion reigns here today!

I'll see if I can get a test case put together.
