The boolean operator
XOR(exclusive or) is not part of the SQL standard, but many databases have support for them (ex. mySQL).However, with the current parser these expressions cannot be parsed as the keyword and the expression for it is not part of the grammar.
This pull request adds support for the XOR Expression, that is treated as a Binary Conditional Operator.
The expression behaves the same as the usual
ANDorORexpressions, but its precedence is the lowest:AND>OR>XOR.
