I am creating a dynamic cursor and I would like to loop over the columns that exist in the cursor. How would I do that?

For example:

create or replace procedure dynamic_cursor(empid in varchar2, RC IN OUT sys_refcursor) as
     stmt varchar2(100);
   begin
     stmt := 'select * from employees where id = ' || empid;
     open crs for stmt using val;

     for each {{COLUMN OR SOMETHING}}
       --TODO: Get this to work
     loop;
end;
