Notes • When you specify DISCONNECT connection_name or DISCONNECT CURRENT and there is
also an established connection to the DEFAULT database, the connection to the DEFAULT
database becomes the current connection. If there is no DEFAULT database, there is no
current connection after the SQL engine processes the DISCONNECT.
• The DISCONNECT DEFAULT statement terminates the connection to the DEFAULT database. If
this connection is the current connection, there is no current connection after this
DISCONNECT statement is executed.
