BIT_AND() function in MySQL

BIT_AND() :

This function in MySQL is used to return the Bitwise AND of all bits in a given expression. It first converts all decimal values into binary values, and then perform bitwise and operation on those binary values.

The BIT_AND() function works by performing a bitwise AND operation on each pair of corresponding bits in the binary representation of the numbers. The result is a new binary number with a 1 in each position.

Note: that BIT_AND() can be used with any integer data type, including BIGINT, INT, MEDIUMINT, SMALLINT, and TINYINT.

Syntax :

BIT_AND(expr)

Parameter : 

This method accepts only one parameter.

• expr – Input expression on which we want to apply BIT_AND function.

Returns :

It returns bitwise AND of all bits in a given expression.

Example-1 :

Working of the BIT_AND function in the columns of table

Creating an Employee Table – 

CREATE TABLE EmployeeDetails(

Employee_Id INT AUTO_INCREMENT,  
Employee_Name VARCHAR(100) NOT NULL,
Working_At VARCHAR(20) NOT NULL,
Work_Location  VARCHAR(20) NOT NULL,
Joining_Date DATE NOT NULL,
Annual_Income INT  NOT NULL,
PRIMARY KEY(Employee_Id )
);

Inserting the values into the table – 

INSERT INTO  
EmployeeDetails(Employee_Name , Working_At, Work_Location, Joining_Date, Annual_Income )

VALUES
('Amit Khan' , 'XYZ Digital' , 'Kolkata' ,'2019-10-06' , 350000 ) ,
('Shreetama Pal' , 'ABC Corp.' , 'Kolkata' ,'2018-12-16' , 500000 )  ,
('Aniket Sharma' , 'PQR Soln.' , 'Delhi' , '2020-01-11' ,300000 ) ,
('Maitree Jana' , 'XYZ Digital' , 'Kolkata' ,'2019-05-01' , 400000 ) ,
('Priyanka Ojha' , 'ABC Corp.' , 'Delhi' ,'2019-02-13' , 350000 ) ,
('Sayani Mitra' , 'XYZ Digital' , 'Kolkata' ,'2019-09-15' , 320000 ) ,
('Nitin Dey' , 'PQR Soln.' , 'Delhi' ,'2019-10-06' , 250000 ) ,
('Sujata Samanta' , 'PQR Soln.' , 'Kolkata' ,'2020-10-06' , 350000 ) ,
('Sudip Majhi' , 'ABC Corp.' , 'Delhi' ,'2018-10-30' , 600000 ) ,
('Sanjoy Kohli' , 'XYZ Digital' ,'Delhi' ,'2019-04-18' , 450000 ) ;

The table will look as follows.

Select * FROM EmployeeDetails;

Output :

Now we will find the BIT_AND of annual income of all the employees company-wise from the “EmployeeDetails” table. 

SELECT Working_At, BIT_AND(Annual_Income) AS BITANDINCOME
FROM employeedetails group by Working_At;

Output :

Example-2 :

Now we will find the BIT_AND of annual income of all the employee location wise from the “EmployeeDetails” table. 

SELECT Work_Location, BIT_AND(Annual_Income) AS BITANDINCOME
FROM EmployeeDetails group by  Work_Location;

Output :

Example-3 :

Creating a Student table –

CREATE TABLE StudentMarks
(
StudentId INT AUTO_INCREMENT,  
StudentName VARCHAR(100) NOT NULL,
Class VARCHAR(20) NOT NULL,
Roll INT NOT NULL,
Sub1Mark INT NOT NULL,
Sub2Mark INT NOT NULL,
Sub3Mark INT NOT NULL,
TotalMarks INT NOT NULL,
PRIMARY KEY(StudentId )
);

Inserting data into the Table –

INSERT INTO StudentMarks
(StudentName, Class, Roll, Sub1Mark, Sub2Mark, Sub3Mark, TotalMarks)
VALUES
('Amit Jana', 'V', 10100, 85, 80, 95, 260),
('Labanya Mallick', 'VI', 11000, 81, 89, 95, 265),
('Virat Sharma', 'VI', 12000, 75, 83, 90, 248),
('Sayani Samanta', 'V', 13000, 95, 90, 99, 284),
('Riyanka Panda', 'V', 14000, 70, 87, 88, 245),  
('Ritika Shah', 'VI', 15000, 78, 89, 90, 257);

The table will look as follows.

SELECT  * from StudentMarks;

Output :

Now we will find the BIT_AND of total marks of all the student class wise from the “StudentMarks” table.

SELECT Class, BIT_AND(TotalMarks) AS BITANDMARKS
FROM StudentMarks group by Class;

Output :
