Eh? Placeholders do work in selects. That last example will take a string (in dd-mon-yyyy format), convert and convert it into a date. The database will then return the result of this, but as a string, using the default database format.

So if NLS_DATE_FORMAT has been set as in the previous messages, then select to_date(?, 'dd-mon-yyyy') from dual; will convert a parameter of '12-aug-2002' into '2002-08-12 00:00:00' (since there's no time component, it'll use midnight, and return all zeros)
