[GRASS-user] Centroid coordinates to database

[Szabó Balázs]

Hi!

It is possible to extract the centroid coordinates into the database?
 
(Sorry about my english, I try to explain my probleme). I have a vector
grass polygon data with mysql database connection. But I want use just
the mysql database with the polygons centroid. So that's why I need
upload to the mysql database (like a column) their centroids
coordinates. So it is possible to get this coordinates in Grass??

many thanks: Balazs
