How To Commit the Current Transaction?

If you have used some DML statements updated some data objects, and you want to have the updates to be permanently recorded in the database, you can use the COMMIT statement. It will make all the database changes made in the current transaction become permanent and end the current transaction. The following tutorial exercise shows you how to use COMMIT statements:

SQL> connect HR/fyicenter

SQL> INSERT INTO fyi_links (url, id) 
  2  VALUES ('fyicenter.com', 101);

SQL> INSERT INTO fyi_links (url, id) 
  2  VALUES ('centerfyi.com', 110);

SQL> SELECT * FROM fyi_links;
     ID URL              NOTES          COUNTS CREATED
------- ---------------- ---------- ---------- ---------
    101 fyicenter.com                          07-MAY-06
    110 centerfyi.com                          07-MAY-06

SQL> COMMIT;
Commit complete.
