SQL2008 R2 SP3中使用pivot实现行转列
同事遇到一个问题，怎么实现行转列，参考了别人的示例，我是这样解决的。
创建数据源：
create table #temp (
objectid int,
sitename nvarchar(32),
cities nvarchar(32),
projectdurationno nvarchar(32),
fullname nvarchar(32),
createdate datetime,
nodename nvarchar(32)
) insert into #temp(objectid,sitename,cities,projectdurationno,fullname,createdate,node_name)values(2,'','海口市','','','10 30 2015 10:26AM','开始')
insert into #temp(objectid,sitename,cities,projectdurationno,fullname,createdate,node_name)values(2,'','海口市','','','10 30 2015 10:26AM','规划库')
insert into #temp(objectid,sitename,cities,projectdurationno,fullname,createdate,node_name)values(2,'','海口市','','','10 30 2015 10:27AM','投资')

方案一、使用pivot进行行转列：
select objectid,SiteName,[开始],[规划库],[投资],[站点],[方案],[集成]
from(
select objectid,sitename,NODE_NAME,createdate from #temp
) as t10
pivot(
max(createdate)
for node_name in
([开始],[规划库],[投资],[站点],[方案],[集成])
) as t11
order by sitename,objectid
方案二、group by 方案
select t10.sitename,t10.objectid,
(case t10.node_name when '开始' then t10.createdate else null end) as '开始',
(case t10.node_name when '规划库' then t10.createdate else null end) as '规划库',
(case t10.node_name when '投资' then t10.createdate else null end) as '投资',
(case t10.node_name when '站点' then t10.createdate else null end) as '站点',
(case t10.node_name when '方案' then t10.createdate else null end) as '方案',
(case t10.node_name when '集成' then t10.createdate else null end) as '集成'
into #temp10
from #temp as t10 select * from #temp10 select objectid,sitename,
max([开始]) as [开始],
max([规划库]) as [规划库],
max([投资]) as [投资],
max([站点]) as [站点],
max([方案]) as [方案],
max([集成]) as [集成]
into #temp12
from #temp10
group by objectid,sitename
对比之后两种方案结果一致。
