A date column, with timestamp..how to remove timestamp

Question

Hi,
I have a table name CATCH, with one of its fieldnamed DATE, using DATE datatype.
The date format incudes timestamp,can anyone help me how to remove the timestamp part.
I only want the date part only. I have tried this:
Update CATCH set DATE=to_char(date,'DD-MON-YYYY');
but the result of all the date inside the table still having timestamp.
then i use this:
Update CATCH set DATE=to_date(date,'DD-MON-YYYY');
and the result still the same.
Can anyone advice on this? pls.
Thanks

Thank you very much..if thats the case, can we remove the timestamp when creating view for this table?no, you can never remove the time component of a DATE.
If you don't want to show the time for a date (display purposes only!), use TO_CHAR to "transform" the DATE to a string with the appropriate format mask
