db.connect - Prints/sets general DB connection for current mapset.

db.connect allows the user to set database connection parameters.  These parameters  are  then  taken  as
       default values by modules so that the user does not need to enter the parameters each time.

       The default database backend in GRASS GIS is SQLite (since version 7).

SQLite(defaultbackend)
       Local storage:
       db.connect -d
       db.connect -p
       db.tables -p

       The SQLite database file is created automatically when used the first time.

       See SQLite database driver for details.

   PostgreSQL(localconnection)
       Local storage, database tables stored in database "mydb" (may require the use of db.login):
       db.connect driver=pg database=mydb
       db.login user=myname pass=secret
       db.connect -p
       db.tables -p

       See PostgreSQL database driver for details.

   PostgreSQL(networkconnection)
       Network storage, database tables stored in database "mydb" (may require the use of db.login):
       db.connect driver=pg database=mydb
       db.login user=myname pass=secret host=myserver.com port=6666
       db.connect -p
       db.tables -p

       See PostgreSQL database driver for details.

   MySQL(localconnection)
       Local storage, database tables stored in database "mydb" (may require the use of db.login):
       db.connect driver=mysql database=mydb
       db.login user=myname pass=secret
       db.connect -p
       db.tables -p

       See MySQL database driver for details.

   MySQL(networkconnection)
       Network storage, database tables stored in database "mydb" (may require the use of db.login):
       db.connect driver=mysql database=mydb
       db.login user=myname pass=secret host=myserver.com
       db.connect -p
       db.tables -p

       See MySQL database driver for details.

   ODBC
       Network storage, database tables stored in database "mydb" (may require the use of db.login):
       db.connect driver=odbc database=mydb
       db.login user=myname pass=secret
       db.connect -p
       db.tables -p

       See ODBC database driver for details.

   DBF(local,notrecommended)
       Local storage (the dbf/ subdirectory in the mapset must exist or must be created by the user):
       db.connect driver=dbf database=’$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/’
       db.tables -p

       See DBF database driver for details.

       database, attribute table, connection settings

db.connect  - Prints/sets general DB connection for current mapset.

       Values are stored in the mapset’s VAR file; the connection is not tested for validity.

       The -p flag will display the current connection parameters.

       The  -c  flag will silently check if the connection parameters have been set, and if not will set them to
       use GRASS’s default values.  (useful in scripts before you attempt to create a new database table)

       To connect a vector map to a database table, use v.db.connect or v.db.addtable.
