DatabaseName (DBN) connection parameter

{ DatabaseName | DBN }=database-name

Running local databases or network database servers.

database-name This string specifies the name of a database that is already running on a database server.

There is no default setting.

If you want to connect to a database that is not running, use the DatabaseFile (DBF) parameter.

Whenever a database is started on a server, it is assigned a database name, either by the administrator using the -n option, or by the server using the base of the file name with the extension and path removed.

You can only use the database name utility_db to connect to the SQL Anywhere utility database. See Utility databases.

Note

The DatabaseName (DBN) connection parameter is recommended for naming databases, rather than using the DatabaseSwitches (DBS) connection parameter with the -n option.

If the database you want to connect to is already running, you should specify the database name rather than the database file.

A connection only occurs if the name of the running database matches the name that is specified in the DatabaseName (DBN) parameter.

Note

If you specify both the database file and the database name, an attempt is made to connect to a running database with the specified name (the database file is ignored), and if that fails, an attempt is made to start a database automatically using both the database file and database name.

To start a database file named cities.db and rename the database Kitchener, run the following command:

dbeng12 cities.db -n Kitchener

Assuming you have run the above command, you can successfully connect to the running database named Kitchener as follows:

DBN=Kitchener

Alternatively, you could use the following to successfully connect to the running database named Kitchener:

DBN=Kitchener;DBF=cities.db

However, specifying the following would fail to connect to the database named Kitchener:

DBF=cities.db
