## NAME

db.dropcol

## 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

## SEE ALSO

db.droptable, db.execute, v.db.dropcol
