db.droptable(1)

NAME
db.droptable - Drops an attribute table.

KEYWORDS
database, attribute table

SYNOPSIS
db.droptable
db.droptable --help
db.droptable [-f] [driver=name] [database=name] table=name [--help] [--verbose] [--quiet] [--ui]

  Flags:

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

--help
    Print usage summary

--verbose
    Verbose module output

--quiet
    Quiet module output

--ui
    Force launching GUI dialog

  Parameters:

driver=name
    Name of database driver
    If not given then default driver is used

database=name
    Name of database
    If not given then default database is used

table=name [required]
    Name of table to drop

DESCRIPTION
db.droptable drops 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.droptable is a front-end to db.execute to allow easier usage. To some extent it is verified if the table is connected to a vector map to avoid accidental table removal.

EXAMPLES

  Removing an attribute table from default database

# show default database
db.connect -p
# show available tables
db.tables -p
# this will show what would happen
db.droptable table=sometable
# actually drop the table
db.droptable -f table=sometable

  Removing an attribute table from given database
db.droptable allows defining optionally driver and database options different from default connection settings (db.connect -p).

# drop the table from SQLite database
db.droptable -f table=sometable driver=sqlite database=/opt/sqlite.db
