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')

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。
