Parameters:
table=name [required]

DESCRIPTION


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.

NOTES


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.

EXAMPLE


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
