    If you want to use XOR as a bit-arithmetic operator, then use function SYS.UTL_RAW.BIT_XOR.

    If you want to use it as a logical operator, then you can construct one yourself.

    For example, you want the result of: "a XOR b", where a and b are expresions that can result in values 0 (FALSE) or 1 (TRUE) and the result of the XOR expression should also result in values 0 (FALSE) or 1 (TRUE). You can construct your own DECODE or CASE expression that returns the XOR result - here is an example with DECODE:

    DECODE(a, b, 0, 1)

    Or without DECODE or CASE you can use:

    MOD(a+b, 2)

    hi jmodic,

    how different is SIGN() function from DECODE or CASE.
    thnx,
    Cheers!

    thnx,
    I realy don't understande your question. I'm sure you know the difference between SIGN() and DECODE()/CASE, so what is your real question? To somehow construct XOR operator using solely SIGN() function? Can you explain a bit more?
