You can also use this statement with the DORMANT option to put the current connection in a dormant state. Use this statement with .
Identifying the Connection

Identifying the Connection

If the application did not specify a connection name in the initial CONNECT statement, you must use a database environment (such as a database name or a database pathname) as the connection name. For example, the following SET CONNECTION statement uses a database environment for the connection name because the CONNECT statement does not use a connection name. For information about quoted strings that specify a database environment, see Database Environment.

CONNECT TO 'stores_demo';
...
CONNECT TO 'demo';
...
SET CONNECTION 'stores_demo';

If a connection to a database server was assigned a connection name, however, you must use the connection name to reconnect to the database server. An error is returned if you use a database environment rather than the connection name when a connection name exists.
