Overview

Note

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.

Examples

List column descriptions of table in SQLite database (note that this is the default setting)

db.describe driver=sqlite table=hospitals \
   database=’$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db’
# or simply
db.describe myarchsites
