sql server 2008 存储过程 将多条数据合并为一条

[酒龄後]

数据1
MARS_TPN2 MARS_CPN2 ERG1SJ471V MARS_TTA(1)
MARS_TPN7 MARS_CPN7 135942-61500910 MARS_TTA(2)
MARS_TPN7 MARS_CPN7 135942-61500910 MARS_TTC(1)

数据2
MARS_TPN2 MARS_CPN2 ERG1SJ471V MARS_TTA(1)
MARS_TPN7 MARS_CPN7 135942-61500910 MARS_TTA(2),MARS_TTC(1)

如何用存储过程，将数据1的数据转化为数据2的数据
求解
在线等
急。。。。。。。。。。。。。。。。。。。。。

还是要写存储过程的 这些数据都是查询出来的 不是固定的数据 麻烦大婶指点

[發糞塗牆]

CREATE PROC test 
AS 
select a.a,a.b,a.c,
stuff((select ','+d from [huang] b 
       where b.a=a.a and b.b=a.b and b.c=a.c
       for xml path('')),1,1,'') 'd'
from [huang] a
group by  a.a,a.b,a.c

exec test
