--部门发文数
select so.fd_name,count(ks.fd_id) as data_value
from km_imissive_send_main ks,sys_org_element so
where ks.fd_sendplan_dept_id =so.fd_id
and fd_is_controller=1
and ks.fd_is_numbered=1
and year(ks.doc_create_time)=year(now())
and so.fd_org_type=2
group by so.fd_name
--初始值
select so.fd_name,sum(kp.fd_num) as data_value
from km_imissive_planp kp,sys_org_element so
where kp.fd_dept_Id=so.fd_id
and kp.fd_is_available=1
and kp.fd_plan_yeat=year(now())
group by so.fd_name
