SYNOPSIS

       db.dropcol
       db.dropcol help
       db.dropcol [-f] table=name column=string  [--verbose]  [--quiet]

   Flags:
       -f
           Force removal (required for actual deletion of files)

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       table=name
           Table from which to drop attribute column

       column=string
           Name of the column

DESCRIPTION

       db.dropcol  drops  a  column  from an attribute table.  If the -f force flag is not given then nothing is
       removed, instead a preview of the action to be taken is printed.

NOTES

       db.dropcol is a front-end to db.execute to allow easier usage with a special workaround  for  the  SQLite
       driver to support column drop.

EXAMPLES

       Dropping a column (Spearfish):

       # work on own copy
       g.copy vect=roads,myroads
       db.describe -c myroads
       # only shows what would happen:
       db.dropcol myroads column=label
       # actually drops the column
       db.dropcol -f myroads column=label
       db.describe -c myroads
