   v.db.dropcol drops a column from the attribute table connected to a
   given vector map. It automatically checks the connection for the
   specified layer. v.db.dropcol omits to delete the 'cat' column which is
   relevant to keep the connection between vector map and table.

ÐÐ ÐÐÐЧÐÐÐЯ

   v.db.dropcol is a front-end to db.execute to allow easier usage. The
   existing database connection(s) can be verified with v.db.connect.
