MySQL ASCII is one of the String Function, which returns the ASCII code of the left most character of a character expression. In this article we will show you, How to use this string ASCII in MySQL with example.

In order to demonstrate this string function, We are going to use the customerdetails table data that we shown below
MySQL ASCII Example 1
The ASCII Function in MySQL is used to return the ASCII code of the leftmost character in an expression. The following query will show multiple ways to use this function.
SELECT ASCII('A'); SELECT ASCII(1); SELECT ASCII('abcd'); SELECT ASCII(''); SELECT ASCII(NULL);
MySQL ASCII Function Example 2
In this example, we are going to implement the string ASCII function on different columns in a table. Following statement will return the ASCII code of leftmost character in First_Name, Last_Name, and Yearly_Income column.
-- MySQL String ASCII Example USE company; SELECT First_Name, ASCII(First_Name) AS ASCII_FName, Last_Name, ASCII(Last_Name) AS ASCII_LName, Education, Profession, Yearly_Income, ASCII(Yearly_Income) AS ASCII_Income, Sales FROM customerdetails;
