[GRASS-user] v.sample value to db column

hej,

is it somehow possible to sample a raster map at given point locations, and put the values directly into a column of the db of the points?
I tried with
v.sample input=segment_points raster=stream_segments column=seg_num
but thats not working...

In following discussion, the same thing is mentioned:
http://wald.intevation.org/tracker/index.php?func=detail&aid=513&group_id=21&atid=205

but is there a simple solution? (I am using GRASS GIS 6.5)

thanks
Johannes
