MySQL ASCII Function

This example illustrates how to find the ASCII value of a string.

In this example we find the ASCII value of name field from emp table. ASCII (American Standard Code for Information Interchange) is used to built-in binary code for representing characters in all computers. It was developed for communications and uses only seven bits per character, providing 128 combinations that include upper and lower case alphabetic letters, the numeric digits and special symbols such as the $ and %. The first 32 characters are set aside for communications and printer control.

Query

SELECT ASCII(name), name FROM emp;

Output
