Transaction Commit When Session Ended in Oracle

Q

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

✍: FYIcenter.com

A

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'
  2  WHERE id = 101;
  
SQL> UPDATE fyi_links SET url = 'CENTERFYI.COM' 
  2  WHERE id = 110;

SQL> disconnect
SQL> connect HR/fyicenter

SQL> SELECT * FROM fyi_links;
     ID URL              NOTES          COUNTS CREATED
------- ---------------- ---------- ---------- ---------
    101 FYICENTER.COM                          07-MAY-06
    110 CENTERFYI.COM                          07-MAY-06
    112 oracle.com                             07-MAY-06
    113 sql.com                                07-MAY-06
