Hi Cherrish!

The statement you are looking for is:
SET hiredate = hiredate + (to_date('1-SEP-03')-to_date('1-NOV-03'));

I didnt see your previous post about Crystal Report so here's my reply from what I could pick up:
Crystal Reports is used to display data from the database. You do not have to know anything about SQL in order to use it - you just drag, click and do stuff with your mouse. When you open the file, you can either export it or print it. It is commonly used in conjunction with Visual Basic or other programming languages used to develop front-ends for database applications.

Best Regards,
