In this article, you will learn how to use the ANY, SOME and ALL operators in MySQL.

Using the ANY, SOME and ALL operators in MySQL

The ANY, SOME, and ALL operators in MySQL are used to compare a value with a set of values returned by a subquery. These operators are also known as quantified comparison operators. They allow you to compare a value with all or some of the values returned by a subquery.

ANY operator

The ANY operator is used to compare a value with any value in a set of values returned by a subquery. Here’s the syntax:

SELECT column1, column2, ...
FROM table_name
WHERE column_name operator ANY (subquery);

For example, let’s say we have a table called “employees” with columns “id”, “name”, and “salary”. If we want to find all the employees whose salary is greater than any employee in the “Sales” department, we can use the following query:

SELECT name
FROM employees
WHERE salary > ANY (
  SELECT salary
  FROM employees
  WHERE department = 'Sales'
);

This query will return all the names of employees whose salary is greater than any employee in the Sales department.

SOME operator

The SOME operator is used to compare a value with some of the values returned by a subquery. It is equivalent to the ANY operator. Here’s the syntax:

SELECT column1, column2, ...
FROM table_name
WHERE column_name operator SOME (subquery);

For example, let’s say we have a table called “orders” with columns “order_id”, “customer_id”, and “order_total”. If we want to find all the orders with a total amount greater than some order made by customer 100, we can use the following query:

SELECT order_id, order_total
FROM orders
WHERE order_total > SOME (
  SELECT order_total
  FROM orders
  WHERE customer_id = 100
);

This query will return the order ID and order total for all the orders with a total amount greater than some order made by customer 100.

ALL operator

The ALL operator is used to compare a value with all of the values returned by a subquery. Here’s the syntax:

SELECT column1, column2, ...
FROM table_name
WHERE column_name operator ALL (subquery);

For example, let’s say we have a table called “orders” with columns “order_id”, “customer_id”, and “order_total”. If we want to find all the orders with a total amount greater than all orders made by customer 100, we can use the following query:

SELECT order_id, order_total
FROM orders
WHERE order_total > ALL (
  SELECT order_total
  FROM orders
  WHERE customer_id = 100
);

This query will return the order ID and order total for all the orders with a total amount greater than all orders made by customer 100.
