SYNOPSIS

       v.db.dropcol
       v.db.dropcol help
       v.db.dropcol map=name  [layer=string]  column=string  [--verbose]  [--quiet]

   Parameters:
       map=name
           Vector map for which to drop attribute column

       layer=string
           Layer where to drop column
           Default: 1

       column=string
           Name of the column to drop

DESCRIPTION

       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.

NOTES

       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.

EXAMPLES

       Dropping a column:

       v.db.dropcol sentiero_brenta_points column=slope
       v.info -c sentiero_brenta_points
