[winGRASS] calculating the area of polygons on vector layers

[Jonathan Aguero]

Dear all,

I am trying to add a new column into the attribute table of a vector layer
and calculate in that column the area of the polygons.

I guess I have to use and SQL statement but I couldn't find anything in the
GRASS help.

Thanks
