Oracle takes System date from the OS. Shut down Oracle, Change the OS date and restart Oracle. That will give you New Systemdate.

If you do not Shut down/ Restart Oracle, it some time creates problems.

Hope this helps.

Hi

Thanks for ur time.

But its not the thing I want. The exact problem is when I make changes in a table, and if some condition satisfies, I will execute a trigger in which I will change the system date itself. (ie; UPDATE.... SYSDATE = '27-Nov-2006') This will create an error , then how can I change the SYSDATE ???

Regards
Reshmi

Hey,

Reshmi is trying to change the SystemDate, not the date format.
It can be done, using a batchfile/shell script, if you want it to be automatic.

date [New Date]

Start listener as - lsnrctl start[listener_name]
Start Database as - sqlplus "/as sysdba"; SQL> startup

hope this helps.
By the way, the above script is for Windows. what are you trying to do?
If you ask your Oracle Admin. they will do it for you.

OK , you may proceed as Pragati has told u .
But through a DML statement like UPDATE it is not possible as SYSDATE works like a function and it can't be used in the left hand side of a = operator .

Might some kind soul take on this Oracle statement and translate it into DB2? Yes ... I know the equivalent of SYSDATE is CURRENT TIMESTAMP, and that DUAL is SYSIBM.SYSDUMMY1. But I'm puzzled by the 'Q' (Quarter), and NEXT_DAY translations. Thanks. SELECT TO_CHAR(SYSDATE, 'Q') Q, TO_CHAR(SYSDATE, 'MM') MON, TO_CHAR(NEXT_DAY(SYSDATE,'SUNDAY' ),'MM/DD/YYYY') WEEKEND,

Hi! We are currently supporting an old application using Win NT 4.0, Oracle 8i, MTS/IIS, and ASP.

Lately, there are times when it displays an invalid date format such as 04/11/197 or 04/11/07. As an immediate solution, we just restart the production server. Do you have any idea...
