- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:

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.
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.
# 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
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
