db.columns --help

db.columns table=name [driver=name] [database=name] [--help] [--verbose] [--quiet] [--ui]

table=name [required]: Name of attribute table
driver=name: Name of database driver; Options: dbf, odbc, ogr, pg, sqlite; Default: sqlite

db.columns lists all columns for a give table. Connection to databases are supported through dbf, shp, odbc and pg drivers.

If parameters for database connection are already set with db.connect, they are taken as default values and do not need to be spcified each time.

db.columns table=zipcodes_wake driver=pg database=grassdb

If the database parameters are already set, the columns can be listed directly

db.columns table=zipcodes_wake

db.columns table=zipcodes_wake driver=dbf database=/grassdata/nc_spm_08/PERMANENT/dbf/

Note that the SQLite backend is the default setting.

db.columns driver=sqlite table=archsites database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db'
