I need to add 11 hours onto a column.
Now this column is in the format of DD-MM-YYYY HH:MMM:SS...My problem is adding the 11 hours on but also altering the DD-MM-YYYY with accordance to additional 11 hours for eg it turns over to the next day...is there any possible way of doing this.....

What is the datatype of this column - date or varchar2? If it is date, the update is very easy. If not, you have made life much harder on yourself.
If date:
update t
set c = c + (11/24);
If varchar2: What is that datetime format? What is MMM? Why 3 Ms? Here is an answer for a valid format (MI instead of MMM):
update t
set c = to_char(to_date(c, 'DD-MM-YYYY HH24:MI:SS') + (11/24), 'DD-MM-YYYY HH24:MI:SS'); |

Select to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS '),
to_char((SYSDATE + (11/24)), 'DD-MON-YYYY HH24:MI:SS')
