Is there any way to "optimize" the following two functions to improve speed? I am calling this type of functions a lot.

Thanks.

function fTest1 (v_id in number) return boolean is   v_date date;
BEGIN
  select max(my_date_field) into v_date from my_table where id= v_id;   if v_date > sysdate - 30 then return true; else return false; end if; EXCEPTION
  when others then return false;
END fTest1;

function fTest2 (v_id in number) return varchar2 is

   text varchar2(32000);
  cursor cur1 is
   select my_text_field from my_table where id= v_id;

BEGIN for x in cur1 loop

text := text || chr(10) || x.my_text_field ; end loop;

return text;

END fTest2;
