Examples of MySQL FORMAT() function:

Now we will look into some MySQL FORMAT() function examples and will explore how to use the FORMAT function in MySQL.

Example-1 :

In this example, we will round off the given number by using the FORMAT() function in MySQL to 2 decimal places.

SELECT FORMAT(555454.12365, 2) AS form;

Output :

form
555, 454.12
1 row in set (0.00 sec)

Example 2:

In this example, we will round off the given number by using MySQL's FORMAT() function with 0 decimal places.

SELECT FORMAT(130919999.456, 0)
AS form;

Output :

form
130, 919, 999
1 row in set (0.00 sec)

Example-3 :

Now we will Replace the en_US locale with the de_D locale.

SELECT FORMAT(27112020.1052, 3, 'de_DE') As form;

Output :

form
27.112.020, 105
1 row in set (0.00 sec)

Example-4 :

When we require to round off the column data, then we can take the help of the FORMAT() function in MySQL.

CREATE TABLE Commodity(
Commodity_Id INT AUTO_INCREMENT,
Commodity_Name VARCHAR(100) NOT NULL,
Price INT NOT NULL,
PRIMARY KEY(Commodity_Id )
);

Inserting values into the table:

INSERT INTO Commodity(Commodity_Name, Price)
VALUES
('MotorolaMobile', 75000.999 ),
('SmartWatch,' 73000.455 ),
('Camera,' 170000.545 ) ;

The table will look as follows.

SELECT * FROM Commodity;

Commodity_Id	Commodity_Name	Price
1	MotorolaMobile	75000.999
2	Smartwatch	73000.455
3	Camera	170000.545

Now we will format the Price column by rounding up to 1 decimal place.

SELECT
Commodity_Name, FORMAT(Price, 1) As New_price
FROM
Commodity;

Output:

Commodity_Name	New_price
MotorolaMobile	75, 001.0
Smartwatch	73, 000.5
Camera	170, 000.5

Summary:

In the above context, we have learned how we can use the FORMAT() function in MySQL used to format given number like '#, ###, ###.##", round them to specific decimal points, and returns the result in the form of a string.
