-->TravyLee生成测试数据：[test]
if object_id('[test]') is not null drop table [test]
create table [test]([type] varchar(3),[Name] varchar(2))
insert [test]
select 'A类','A1' union all
select 'B类','B1' union all
select 'A类','A2' union all
select 'B类','B2'

select distinct [type] as [type],[Name]='' from test
union all
select * from test
order by [type],[Name]
/*
type    Name
A类    
A类    A1
A类    A2
B类    
B类    B1
B类    B2
*/
