MySQL BIN Function

MySQL BIN function is one of the String Functions, which is to return the string representation of the binary value of a number. The basic syntax of the BIN Function is as shown below:

SELECT BIN(Numeric_Expression)
FROM [Source]

Numeric_Expression: Please specify a valid Expression or Number. It accepts up to BIG INT. To demonstrate this, We are going to use the customerdetails table data that we showed below

MySQL BIN Function Example

The String BIN returns the Binary Values of the given numeric expression. The following query shows multiple ways to use this function.

SELECT BIN(12);

SELECT BIN(4029);

-- Let me use NULL value as input
SELECT BIN(NULL);

-- It Omits the decimal values
SELECT BIN(12.56);

SELECT BIN('A');

In this method example, we are going to implement it on different columns in a table. The following MySQL statement returns the Binary values of the data present in Yearly_Income and Sales Columns.

USE company;
SELECT  First_Name, 
		Last_Name,
        Education, 
        Profession, 
        Yearly_Income, 
        BIN(Yearly_Income) AS Binary_Income,        
        Sales,
        BIN(Sales) AS Binary_Sales 
FROM customerdetails;
