What Happens to the Current Transaction If the Session Is Ended?

If a session is ended, the current transaction in that session will be committed and ended. All the
database changes made in the current transaction will become permanent. This is called an
implicit commit when session is ended. The following tutorial exercise shows you that the
"disconnect" command forces the current transaction to be committed and ended. When the
session is reconnected, you can see the changes made by the UPDATE statements.
SQL> connect HR/fyicenter
SQL> UPDATE fyi_links SET url = 'FYICENTER.COM' WHERE id = 101;
SQL> UPDATE fyi_links SET url = 'CENTERFYI.COM' WHERE id = 110;
SQL> disconnect
SQL> connect HR/fyicenter
SQL> SELECT * FROM fyi_links;
