If I'm reading between the lines right, I'm guessing you don't want to change application code. You can optionally implement the table in Oracle with a 'virtual' column, which would be defined with the to_char function allowing you to mask the function from the app (no change to SQL). Or you can create a view to do the same thing.
See the syntax for the CREATE TABLE statement to see how to implement a virtual column.
