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
