Here is one way:

select 'A' as letter from dual union all
select 'B' from dual union all
. . . 
select 'Z'
order by letter

(Where the ... is just similar lines for the other letters).

Seems like a curious question, though.

DECLARE a number;

BEGIN

FOR a in ascii('A') .. ascii('Z') LOOP

   dbms_output.put_line(chr(a));

END LOOP; END;
