More Information

 EXIT stops an interactive SQL session and returns you to the DCL
 prompt.

 Typing CTRL/Z is the same as issuing the EXIT statement.  If you
 have made uncommitted changes to the database when you issue the
 EXIT statement, SQL asks whether you want to roll back the
 transaction:

 There are uncommitted changes to this database.
 Would you like a chance to ROLLBACK these changes (No)?

 If you answer YES to the prompt, SQL returns you to the SQL
 prompt.  If you do not answer and type RETURN, or answer NO, SQL
 commits all changes made since the last COMMIT or ROLLBACK
 statement.
