driver=name

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 accidential 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
