MariaDB ORD() Function



The MariaDB ORD() function returns the character code for leftmost character of the argument.

If the leftmost character of the argument is a multibyte character, this function returns the code for that character, calculated from the numeric values of its constituent bytes using formula given below:

  (1st byte code)
+ (2nd byte code * 256)
+ (3rd byte code * 256^2) ...

If the leftmost character of the argument is not a multibyte character, this function returns the same value as the ASCII() function.

Syntax
