What Happens to the Current Transaction If the Session Is Ended?
Submitted by: AdministratorIf 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/globalguideline
SQL> UPDATE ggl_links SET url = 'globalguideline.COM'
2 WHERE id = 101;
SQL> UPDATE ggl_links SET url = 'globalguideline.COM/html'
2 WHERE id = 110;
SQL> disconnect
SQL> connect HR/globalguideline
SQL> SELECT * FROM ggl_links;
<pre> ID URL NOTES COUNTS CREATED
