For treating the hexadecimal value as a number, we can use the CAST(… AS UNSIGNED) function. Following example will demonstrate it −
mysql> Select 0x54, CAST(0x54 AS UNSIGNED); +------+------------------------+ | 0x54 | CAST(0x54 AS UNSIGNED) | +------+------------------------+ | T | 84 | +------+------------------------+ 1 row in set (0.01 sec)
