MySQL: Simple way to toggle a value of an int field

Question

I know how to do this, but i think I\'ll overcomplicate it with double selects and so on.

How can you do this (example in pseudo-sql)

UPDATE some_table S         


        

Answer 1

If you're using TINYINT (0 and 1) then do a simply XOR (https://dev.mysql.com/doc/refman/8.0/en/logical-operators.html#operator_xor)

UPDATE
    `some_table`
SET
    `an_int_value` = `an_int_value` ^ 1

Testing:

SELECT 0 ^ 1; /* returns 1 */

SELECT 1 ^ 1; /* returns 0 */
