EXEC SQL
CONNECT TO DEFAULT ;

** C Language and embedded SQL application processing against the
** database in the connect_string
*/

EXEC SQL
DISCONNECT DEFAULT ;
After you issue DISCONNECT ALL there is no current connection. The following example
disconnects all database connections:
EXEC SQL
DISCONNECT ALL;
The following example illustrates the CONNECT, SET CONNECTION, and DISCONNECT statements
in combination using these steps:
1. CONNECT TO connect_string AS connection_name, which establishes a connect_string
connection to the database in the connect_string; the connection has the name 'conn_1'.
2. CONNECT TO DEFAULT, which establishes a connection to the DEFAULT database and sets this
connection current.
3. DISCONNECT DEFAULT, which disconnects the connection to the DEFAULT database.
4. SET CONNECTION connection_name, which sets the 'conn_1' connection current.
5. DISCONNECT CURRENT, which disconnects the 'conn_1' connection.
