The said query in SQL that retrieves all employees from the 'employees' table who do not belong to the 'MARKETING' department.

The WHERE clause filters all employees whose department ID is not in the list of department IDs associated with the 'MARKETING' department.

The subquery that selects the department ID(s) associated with the 'MARKETING' department.

The subquery is executed first, and its result is used in the main query to filter the rows from the employees table.
