Bitwise exclusive OR in Oracle
From the docs:
function bitor(p1 number, p2 number) return number is
begin
return p1-bitand(p1,p2)+p2;
end;
function bitxor(p1 number, p2 number) return number is
begin
return bitor(p1,p2)-bitand(p1,p2);
end;
To see that these work, follow the logic with just 0s and 1s for input, and then not that there are no borrow or caries.

There is the BITAND operator:
select bitand(49,54)+0 from dual;
You can build up the other operators from it.
There's no easy way.
You may cast string HEX
values into RAW
values and use UTL_RAW
:
SELECT UTL_RAW.bit_xor(HEXTORAW(TO_CHAR(1, 'FMX')), HEXTORAW(TO_CHAR(2, 'FMX')))
FROM dual
