复制代码 代码如下:
–create database dbtemp
use dbtemp
create table test
(
pid int identity(1,1) not null primary key,
years datetime,
isfirstsixmonths int default(0), –0表示上半年1表示下半年–
totalcome int
)
insert test
select ‘2007-1-1’,0,50
union
select ‘2007-3-1’,0,60
union
select ‘2007-12-1’,1,80
union
select ‘2008-1-1’,0,100
union
select ‘2008-12-1’,1,100
select * from test
select convert(char(4),years,120) as ‘year’,
isfirstsixmonths=case when isfirstsixmonths=0 then ‘上半年’ when isfirstsixmonths=1 then ‘下半年’ end ,
sum(totalcome) as ‘sum’ from test
group by isfirstsixmonths,convert(char(4),years,120)
select convert(char(4),years,120) as ‘year’,
isfirstsixmonths=case when isfirstsixmonths=0 then ‘上半年’ else ‘下半年’ end ,
sum(totalcome) as ‘sum’ from test
group by isfirstsixmonths,convert(char(4),years,120)
–drop database dbtemp
结果如下:
复制代码 代码如下:
2007 上半年 110
2007 下半年 80
2008 上半年 100
2008 下半年 100
