使用SQL实现小计,合计以及排序

--说明：个人学习笔记，实现小计合计显示，分组按bank_id+op_date升序排序

--测试数据
create table #tb(id varchar(10),bank_id varchar(10),op_date varchar(10),operator_no varchar(20),amt decimal(10,2))
insert #tb select '1111','001','20121210',1234567,111.00
union all select '2222','002','20121210',1234567,222.00
union all select '3333','001','20121112',1234567,250.00
union all select '4444','002','20121110',1234567,330.00
union all select '5555','001','20121210',1234567,300.00
union all select '6666','002','20121112',1234567,150.00
go

--查询
select a.id
 ,a.bank_id
 ,a.amt
 ,b.op_date
 ,b.operator_no
from
(
(select
 id=case
  when grouping(bank_id)=1 then '合计'
  when grouping(id)=1 then '小计'
  else id end
 ,bank_id
    ,sum(amt) amt
    ,order_sign1=grouping(bank_id),order_sign2=bank_id
    ,order_sign3=grouping(id)
from #tb
group by bank_id,id with rollup
having grouping(id)=1
union all --先得出表的统计，再加上表中的数据
select id
 ,bank_id
 ,amt
 ,order_sign1=0,order_sign2=bank_id
    ,order_sign3=0
 from #tb) a
left join --为了显示出op_date、operator_no
(select id
 ,op_date
 ,operator_no
from #tb) b on a.id = b.id
) order by order_sign1,order_sign2,order_sign3,op_date

go

--删除测试
