The short answer is: no, you cannot solve the problem without post processing the points.

Subject: [fdo-users] FDO spatial query
hi, I need to create FDO query to return set of points in specific order.
To explain problem easiest way - imagine you have predefined route (line)
and want to return list gas stations (points) along that route with nearest
Only solution I was able to create was FDO_SELECT command with
(usually they are in some short distance to this line, but make it simplier
and assume points are exactly on line)
collection of points returned was ok, but in random order.
Any ideas (even with different technology like FDO) how to solve this are
welcome. My goal is to manage geometry only with using some library and do
not write complex algorithms dealing with different geom. types like
linestring curvestring etc.
