The SQLite driver is the default DBMI backend.
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/$MAPSET/sqlite/sqlite.db’ db.connect -p
All SQL commands supported by SQLite (for limitations, see SQLite help page: SQL As Understood By SQLite and Unsupported SQL).
All SQL operators supported by SQLite.
A convenient SQLite front-end is sqlitebrowser. To open a DB file
stored within the current mapset, the following way is suggested
(corresponds to above database connection):
# fetch GRASS variables as shell environment variables: eval `g.gisenv` # use double quotes: sqlitebrowser "$GISDBASE/$LOCATION_NAME/$MAPSET"/sqlite/sqlite.db
db.connect, db.execute, db.select
