下面的sql 能转成 hql吗

select x.file_dept,sum(decode(destroy_state,'0',1,0)) as destroy, sum(decode(x.cams_state,'2',1,0)) as yigd,
sum(decode(x.cams_state, '1',1,0))as yugd,sum(x.yqs)
from (
select t.file_dept,t.destroy_state,t.cams_state
,case when (select count(1) from cams_archives_delay a where a.cams_id=t.cams_id) > 0
then 1 else 0 end as yqs from Cams_Archives t where 1=1 ) x where 1=1 group by x.file_dept
