db.dropcolumn - Drops a column from selected attribute table.

       Markus Neteler

db.dropcolumn 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.

       Dropping a column (North Carolina sample dataset):

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

       database, attribute table

db.dropcolumn  - Drops a column from selected attribute table.

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