（SOS）sql怎么多行转一行？

Question

原表查询出来是下面例1数据，现在需要把ID下面逗号的东西都分开来显示成例2的情况!!!其中name这一列基本上都不一样，ID输出的数字也可能是随机的（也就是说并不是只显示下面11种数字）~~求各位大大帮忙看语句怎么写。谢谢了

Answer 1

---测试数据---
if object_id('[tb]') is not null drop table [tb]
go
create table [tb]([name] varchar(1),[ID] varchar(20),[DATE] datetime)
insert [tb]
select 'a','12134','2010-12-7' union all
select 'b','214524,325447,414544','2010-12-5' union all
select 'c','22455,3154','2010-12-6' union all
select 'd','521154','2010-12-7' union all
select 'e','5114,432,615236','2010-12-6' union all
select 'f','21234','2010-12-6'
 
---查询---
select 
  a.name,
  id=substring(a.id,b.id,charindex(',',a.id+',',b.id)-b.id),
  convert(varchar(10),[date],120) [date] 
from 
  tb a,(select top 100 id=row_number() over(order by getdate()) from sys.columns,sys.objects)b
where
  charindex(',',','+a.id,b.id)=b.id 
order by 
  a.name,id---结果---
name id                   date
