A list of all staff currently employed by one org

Question

User want list of all staff currently employed by XXXX organization.
I ran this query
  SELECT papf.employee_number, papf.first_name, papf.last_name
    FROM per_all_people_f papf,
         per_all_assignments_f paaf,
         hr_all_organization_units haou
   WHERE     1 = 1
         AND paaf.organization_id = haou.organization_id
         AND papf.person_id = paaf.person_id
         AND TRUNC (SYSDATE) BETWEEN papf.effective_start_date
                                 AND papf.effective_end_date
         AND TRUNC (SYSDATE) BETWEEN paaf.effective_start_date
                                 AND paaf.effective_end_date
         AND haou.name = 'XXXXX'
--and papf.employee_number is not null
-- and papf.current_employee_flag= 'Y'
GROUP BY papf.employee_number, papf.first_name, papf.last_name
The user said this is wrong data, some eployee number is not and the number of employees are more than my extract.
Please help me with query.

HI,
you aren't necessarily looking at current employees, i.e ones where the per_periods_of_service actual_termination_date is null or in the future for the assignments,
additionally you could be pulling in Applicatnt , Benefit , contingent worker assignments too.
try
    SELECT papf.employee_number, papf.first_name, papf.last_name
        FROM per_all_people_f papf,
             per_all_assignments_f paaf,
              per_periods_of_service pps,
             hr_all_organization_units haou
       WHERE     1 = 1
             AND paaf.organization_id = haou.organization_id
             AND papf.person_id = paaf.person_id
             AND papf.person_id = pps.person_id
            AND pps.period_of_service_id = pps.period_of_service_id
            AND paaf.assignment_type in ('E','C')
            AND trunc(sysdate) <= nvl(pps.actual_termination_date, trunc(sysdate))
      AND TRUNC (SYSDATE) BETWEEN papf.effective_start_date
                                   AND papf.effective_end_date
           AND TRUNC (SYSDATE) BETWEEN paaf.effective_start_date
                                   AND paaf.effective_end_date
           AND haou.name = 'XXXXX'
GROUP BY papf.employee_number, papf.first_name, papf.last_name
