MySQL XOR Operator

by

MySQL XOR Operator is one of the Logical Operator. In mathematics, x XOR y is equal to (x AND (NOT y)) OR ((NOT x) AND y). Generally, we use this MySQL XOR operator in the WHERE Clause to apply multiple filters on the rows or records returned by SELECT Statement.

This XOR operator returns the result as:

  • 1, if all operands are no nulls, and if an odd number of operands are non-zero, otherwise 0.
  • NULL, If either of the operands is NULL.

To explain the MySQL Logical Operator XOR in the WHERE Clause, we are going to use the below shown data.

MySQL XOR Operator 0

MySQL XOR Operator Command prompt

In this example, we pass Ones, Zeros, and Null values with a different combinations. This example helps you to understand the Truth table behind this XOR Operator.

-- MySQL XOR Operator Example

SELECT 1 XOR 1;

SELECT 1 XOR 0;

SELECT 0 XOR 0;

SELECT 1 XOR NULL;

SELECT 1 XOR 1 XOR 1 XOR 0;

SELECT 0 XOR NULL;

MySQL XOR Example

The XOR Operator test multiple conditions in WHERE Clause. If either one of the conditions in the where clause is TRUE, then the statement displays the records.

-- MySQL XOR Operator Example
USE company;
SELECT CustID,
		First_Name, Last_Name,
        Education, Profession,
        Yearly_Income, Sales
FROM customers
WHERE Education = 'High School'
	XOR Yearly_Income > 90000;
