   v.db.addcol adds one or more column(s) to the attribute table connected
   to a given vector map. It automatically checks the connection for the
   specified layer.

ÐÐ ÐÐÐЧÐÐÐЯ

   v.db.addcol is a front-end to db.execute to allow easier usage. The
   supported types of columns depend on the database backend. However, all
   backends should support VARCHAR, INT, DOUBLE/REAL and DATE. The default
   dbf backend supports only these types. The existing database
   connection(s) can be verified with v.db.connect.

ÐÐ ÐÐÐРЫ

   Adding a single column:

v.db.addcol sentiero_brenta_points columns="slope double precision"
v.info -c sentiero_brenta_points

   Adding two columns:

v.db.addcol sentiero_brenta_points columns="slope double precision,myname varch
ar(15)"
v.info -c sentiero_brenta_points
