db.droptable(1grass) GRASS GIS User's Manual db.droptable(1grass)

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:


Force removal (required for actual deletion of files)

Print usage summary

Verbose module output

Quiet module output

Force launching GUI dialog

Parameters:


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

Name of database
If not given then default database is used

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
