Class::DBI is (wisely) quoting all of your input before it puts it in an SQL query. What the database sees is something like this: 
update tablename set foo = 'bar', 
date = 'to_date( \'03/03/2004\', \'MM/DD/YYYY\' )'
where id = '1'

It tries to set the date column to the string "to_date( '03/03/2004', 'MM/DD/YYYY' )" and fails.

You'll have to do any date calculations & conversions yourself and pass in the result using whatever format Oracle recognizes (unix epoch? YYYYMMDDHHMMSS format?). Or maybe even use attribute inflation/deflation to make your life a little easier. Just pass in (for instance) a Time::Piece object instead of a date string. There's even an example of this using Time::Piece in Class::DBI's POD.

Bottom line: For safety reasons, anything you set your Class::DBI objects' fields to will never be interperted as SQL. Otherwise, its queries would fail every time you did something involving quotation marks.
