如何显示每个成本中心的所有数据

Question

有人可以帮我解决有关数据显示的问题吗？

SCREENSHOT A.

SCREENSHOT B

参考上面的屏幕截图，应该显示SCREENSHOT B而不是SCREENSHOT A.这是我的查询：

select
c.department_description,
e.cost_center_code,
sum(a.cdr_charge_amount)as total
from cdr_employees a
join employees b on a.employee_id = b.employee_id
join departments c on b.department_id = c.department_id
join employee_cost_centers d on b.employee_id = d.employee_id
join cost_centers e on d.cost_center_id = e.cost_center_id
where a.cdr_datetime > '2016-01-01 00:00:00' 
group by c.department_description, e.cost_center_code 
order by c.department_description

我该怎么办？我应该使用什么查询来显示SCREENSHOT B等数据？

提前致谢。
