语法写的有问题。

select sum(nc),sum(bq),sum(qm)
--注释部分应写到from 后面 作为一个‘表’存在的。
--(
--select sum(jige) as nc,0 as bq,0 as qm from s_zhgl_Office_dn --where --to_char(Reghumdate,'yyyy') = to_char((getdate()-1),'yyyy')
--union all
--select 0 as nc,sum(jige) as bq,0 as qm from s_zhgl_Office_dn --where --to_char(Reghumdate,'yyyy') = to_char((getdate()),'yyyy')
--union all
select 0 as nc,0 as bq,sum(jige) as qm from s_zhgl_Office_dn --where --to_char(Reghumdate,'yyyy') = to_char((getdate()+1),'yyyy')
--)
from s_zhgl_Office_dn

--语法：
--select 字段 from 表 where 条件

你这是要干嘛呢?
datepart(Reghumdate,'yyyy') = datepart(getdate(),'yyyy')-1 ???
