报表问题???
实现下列情况:
出单日期 公司 金额
2007-1-1 A 33
2007-1-1 B 44
合计: 77
2007-1-2 C 33
2007-1-2 D 55
合计: 88
在.net2005的报表项目中中实现按时间汇总
------解决方案----------------------创建建测试环境
create table #t(date datetime,company varchar(20),amount int)
--插入测试数据
insert #t(date,company,amount)
select '2007-1-1 ', 'A ', '33 ' union all
select '2007-1-1 ', 'B ', '44 ' union all
select '2007-1-2 ', 'C ', '33 ' union all
select '2007-1-2 ', 'D ', '55 '
--求解过程
select date,case when grouping(company) = 1 then '合计: ' else company end as company
,sum(amount) from #t
group by date,company with rollup
having grouping(date) = 0
--删除测试环境
drop table #t
/*--测试结果
date company
