In this article, we would like to show you UPDATE query with LIMIT in MySQL.

Practical example

To show you UPDATE query with LIMIT, we will use the following users table:

MySQL - example data used to present UPDATE query with LIMIT
MySQL - example data used to present UPDATE query with LIMIT

Note:

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

Example

In this example, we will update department_id column value for users from id value 3 (excluding user with id = 3). We will also limit the update to 4 users.

Query:

UPDATE `users` SET `department_id`= 10
WHERE `id` IN (
    SELECT `id` FROM (
        SELECT `id` FROM `users` 
        ORDER BY `id` ASC  
        LIMIT 3, 4
    ) subquery
);

Result:

MySQL - UPDATE query with LIMIT - result
MySQL - UPDATE query with LIMIT - 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', 1, '6500.00'),
	('Gwendolyn', 'James', 2, '4200.00'),
	('Simon', 'Collins', 4, '3320.00'),
	('Taylor', 'Martin', 2, '1500.00'),
	('Andrew', 'Thompson', 1, '2100.00');
