SQL & PL/SQL

I've converted date formats many times, but for some reason I'm getting an invalid number error when trying to convert a varchar2 column. I've tried the to_char and to_date function and I get the same result. The column is a date and it is formatted as DD-MON-YYYY, but I want to change it to MM/DD/YYYY. My query is below:

select to_date('fccpdate','MM/DD/YYYY')
from cc_class_scmast_v

When I try to_date I get this:

Error starting at line 1 in command:
select TO_DATE('fccpdate', 'DD-MON-YYYY') from cc_class_scmast_v where fccpdate IS NOT NULL
Error report:
SQL Error: ORA-01858: a non-numeric character was found where a numeric was expected
01858. 00000 - "a non-numeric character was found where a numeric was expected"
*Cause: The input data to be converted using a date format model was
incorrect. The input data did not contain a number where a number was
required by the format model.
*Action: Fix the input data or the date format model to make sure the
elements match in number and type. Then retry the operation.



When I try to_char I get this:

Error starting at line 1 in command:
select TO_char('fccpdate', 'DD-MON-YYYY') from cc_class_scmast_v where fccpdate IS NOT NULL
Error report:
SQL Error: ORA-01722: invalid number
01722. 00000 - "invalid number"
*Cause:
*Action:


I've tried removing the single quotes from my column and that doesn't make a difference. Any help is appreciated.
