ASCII table listing from SQL

Today I was chasing the relevant ASCII code for certain characters... I know there are plenty of ASCII tables on the net, but this is an interesting SQL solution, nonetheless.

select rownum "dec"
      ,chr(rownum) "char"
      ,to_char(rownum,'XXXX') "hex"
from dual connect by level < 256;

dec char    hex
