Table schema:
CREATE TABLE staff_department_assignments (staff_id VARCHAR, job_title_code VARCHAR); CREATE TABLE staff (staff_id VARCHAR, staff_gender VARCHAR)

Question: What are the staff ids and genders of all staffs whose job title is Department Manager?
SQL: 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"
