The SQLite driver is the default DBMI backend.

Creating a SQLite database

GRASS is automatically creating the SQLite database if it is not yet existing when the first table is created in the SQLite database. It is sufficient to define the connection (see next step).

The database name 'sqlite.db' is at user's choice. Also the file storage location can be freely chosen. If the database does not exist, it will be automatically created when database content is created:

# example for storing DB in mapset directory (keep single quotes):
db.connect driver=sqlite database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db'
db.connect -p

# fetch GRASS variables as shell environment variables:
eval `g.gisenv`
# use double quotes:
sqlitebrowser "$GISDBASE/$LOCATION_NAME/$MAPSET"/sqlite/sqlite.db
