exclusive OR in stored procedures

Is it possible to perform an exclusive OR operation in a stored procedure? I need to be able to receive a value ($a) and do a lookup ($b), returning 1 if (($a XOR $b) < $a) or ($b>$a)) -- otherwise returning 0. -- DCP

(when $a XOR $b = $a, the both $a and $b are 0.. and it should return 0). Some examples might help.. 65 xor 4 = 69 (return 0) 65 xor 64 = 1 (return 1) 65 xor 1 = 64 (return 1) 65 xor 16 = 81 (return 0) 65 xor 65 = 0 (return 0) 132 xor 4 = 128 (return 1) 132 xor 16 = 148 (return 0) -- DCP
