[GRASS-dev] Re: query vector points x,y

(...)

Indeed, if I enter the command
v.to.db -p map=mymap type=point opt=coor column=dummy_x,dummy_y,dbl_3
or
v.to.db -p map=mymap type=point opt=coor column=dummy_x,dummy_y
I receive the rows
cat|x|y|z
and not any other field (for example dbl_3).

Well, you are asking for opt=coor and that's what you are getting. Now
you'd have to combine the v.to.db opt=coor output with db.execute output.

Sorry.

OK, but then I think it is better to use v.out.ascii for this purpose!
v.out.ascii print coordinates with high precision, while v.to.db gives only
a couple of decimals after floating point. Why?
