Explanation:

The said query in SQL that retrieves all the rows from the 'employees' table and order them first by the "dep_id" column in ascending order, and then by the "job_name" column in descending order.

This means that the employee records will be grouped first by department ID in ascending order, and within each department, the records will be ordered by job name in descending order.
