RE: Offline doubt - Exclusive OR operator in PL/SQL??.

I said it was a bit xor. Your first message was not very specific. There is no general xor operator in Oracle. However under Oracle 8i you can create one. Look at the create operator command.

You could also do something like

(select x from A where y = 2
union
select x from A where z = 2)
minus
(select x from A where y = 2
intersect
select x from dual where z= 2)

The only reference I found in the documentation was in the UTL_RAW package.

BIT_XOR Function
This function performs bitwise logical "exclusive or" of the values in RAW r1 with RAW r2 and returns the "xor'd" result RAW.

If r1 and r2 differ in length, then the "xor" operation is terminated after the last byte of the shorter of the two RAWs, and the unprocessed portion of the longer RAW is appended to the partial result.The result length equals the longer of the two input RAWs.

Syntax
UTL_RAW.BIT_XOR (
   r1 IN RAW,
   r2 IN RAW)
  RETURN RAW; Pragmas
pragma restrict_references(bit_xor, WNDS, RNDS, WNPS, RNPS);

Parameters
Table 63-40 BIT_XOR Function Parameters
