    hi friends,
    in the date related columns, i am getting values in mm/dd/yyyy format. i need the full datestamp including the hours,minutes and seconds. I tried to change the nls_date_format to include those without success. How to change the format?

    Try this
    SQL> SELECT sysdate from dual;

    SYSDATE
    ---------
    14-DEC-00

    SQL> ALTER SESSION
    2 set nls_date_format = "MM/DD/YYYY";

    Session altered.

    SQL> SELECT SYSDATE from dual;

    SYSDATE
    ----------
    12/14/2000

    SQL> alter session set nls_date_format = "MM/DD/YYYY :HH:MI:SS"
    2 /

    Session altered.

    SQL> SELECT SYSDATE from dual;

    SYSDATE

    thanks soumya,
    but this will only work for that particular session.
    I am interested in making the change permanent and across all users
    thanks

    i did change the nls_date_format="MM/DD/YYYY :HH:MI:SS" .
    However, the change is not reflected in the values.
    I have not restarted the database, as I think this is a dynamically modifiable parameter right?
    Thanks

    If you change something in init.ora, you have to reboot the db before it takes effect.

    Shouldn't you be using TO_CHAR function for this ?

    select to_char(sysdate, 'mm-dd-yyyy hh:mi:ss') from dual;

    You can change the format to many other available forms.

    I think he wanted it default though, but that's right, if everthing used to_char and the format it would work.

    Depending on how your users are accessing the database you could dynamically change their NLS_DATE_FORMAT environment variable to the new format and it will use the new one as default.

    Otherwise if you change it in the init.ora you will need to bounce the database.
