In this article, we would like to show you how to use UPPER() function in MySQL.

Quick solutions:

SELECT UPPER('some text...');
SELECT UPPER(`column_name`) FROM `table_name`;

Practical example

To show how the UPPER() function works, we will use the following table:

MySQL - example data used with UPPER() function
MySQL - example data used with UPPER() function

Note:

At the end of this article you can find database preparation SQL queries.

Example

In this example, we will display all the names from users table in uppercase.

Query:

SELECT UPPER(`name`) AS `Uppercase names` FROM `users`;

Output:

MySQL - UPPERCASE() function result
MySQL - UPPERCASE() function result

Database preparation

create_tables.sql file:

CREATE TABLE `users` (
	`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
	`name` VARCHAR(50) NOT NULL,
	`surname` VARCHAR(50) NOT NULL,
	`department_id` INT(10) UNSIGNED,
    `salary` DECIMAL(15,2) NOT NULL,
	PRIMARY KEY (`id`)
);

 insert_data.sql file:

INSERT INTO `users`
	( `name`, `surname`, `department_id`, `salary`)
VALUES
	('John', 'Stewart', 1, '3512.00'),
	('Chris', 'Brown', 2, '1344.00'),
	('Kate', 'Lewis', 3, '6574.00'),
	('Ailisa', 'Gomez', NULL, '6500.00'),
	('Gwendolyn', 'James', 2, '4200.00'),
	('Simon', 'Collins', 4, '3320.00'),
	('Taylor', 'Martin', 2, '1500.00'),
	('Andrew', 'Thompson', NULL, '2100.00');
