求 行间 时间格式化的SQL 语句！！

比如有如下表

create table t_temp
(
TempId int identity(1,1) primary key,
TempName nvarchar(20),
AddTime datetime
)

insert into t_temp (TempName,AddTime) values('张三','2014-01-01 11:05:00')
insert into t_temp (TempName,AddTime) values('李四','2014-01-01 11:30:00')
insert into t_temp (TempName,AddTime) values('王五','2014-01-01 12:00:00')
insert into t_temp (TempName,AddTime) values('张三','2014-01-02 21:00:00')
insert into t_temp (TempName,AddTime) values('李四','2014-01-02 19:00:00')
insert into t_temp (TempName,AddTime) values('王五','2014-01-02 23:00:00')

select * From t_temp order by AddTime 后结果如下：


请问如何生成一下样式结果集，日期一样的，则只显示第一个全日期，后面的数据仅显示时间：
1 张三 2014-01-01 11:05:00
2 李四 11:30:00
3 王五 12:00:00
4 李四 2014-01-02 19:00:00
5 张三 21:00:00
6 王五 23:00:00
