MySQL String ORD Function

The MySQL string ORD function is one of the MySQL String Functions, which is to find the code of the leftmost character in a string.

  • If the leftmost character is multibyte, the ORD function uses the formula to calculate the code: (1st-byte code) + (2nd-byte code *256) + (3rd-byte code * 256^2)….
  • If the leftmost character is not a multibyte character, this MySQL string ORD function writes the ASCII code of that byte.

Within the first two statements, we used multiple values. However, this MySQL function returns the ASCII code value of the first character. In the third statement, we used a different character. So, this String Function used the formula to get that code.

SELECT ORD('213');

SELECT ORD('¥z');
