XOR

>>-XOR--(--expression----,--expression-+--)--------------------><
The XOR function returns a string that is the logical XOR of
the argument strings. This function takes the first argument string, does
an XOR operation with the next string, and then continues to do XOR operations
for each successive argument using the previous result. If an argument is
encountered that is shorter than the previous result, it is padded with blanks.
The arguments must be compatible.
- expression
- The arguments must be expressions that return a value of any built-in
numeric or string data type, but cannot be LOBs. The arguments cannot be mixed
data character strings, UTF-8 character strings, or graphic strings. A numeric
argument is cast to a character string before evaluating the function. For
more information on converting numeric to a character string, see VARCHAR.
The arguments are converted, if necessary, to the attributes of the result.
The attributes of the result are determined as follows:
- If all the arguments are fixed-length strings, the result is a fixed-length
string of length n, where n is
the length of the longest argument.
- If any argument is a varying-length string, the result is a varying-length
string with length attribute n, where n is the length attribute of the argument with greatest length attribute.
The actual length of the result is m, where m is the actual length of the longest argument.
If an argument can be null, the result can be null; if an argument is null,
the result is the null value.
The CCSID of the result is 65535.
