Hello!  Can you provide me with a list of all Job Title Codes present on this list?
select job_title_code from staff_department_assignments
Great!  Can you please show me a list of Staff IDs for those who have the job_title_code of Department Manager?
select t1.staff_id from staff as t1 join staff_department_assignments as t2 on t1.staff_id = t2.staff_id where t2.job_title_code = "Department Manager"
Great!  Now can you update this list to include the genders of all of these individuals?
select t1.staff_id, t1.staff_gender from staff as t1 join staff_department_assignments as t2 on t1.staff_id = t2.staff_id where t2.job_title_code = "Department Manager"
