SQL & PL/SQL

Dear all,
i like to SELECT SYSDATE FROM DUAL, and run this result in a query something like:

SELECT X, Y, Z FROM TABLENAME WHERE ACCESSDATE = (SELECT SYSDATE FROM DUAL);

The problem is that the value of ACCESSDATE is in an format like DD-MM-YYYY and that sysdate form dual is
DD-MON-YYYY.

How do i get sysdate into the format DD-MM-YYYY?

Thanks already,
Johan.
