帮顶给分不?

---

sybase不支持自定义函数，没办法

---

你可以参考临时表和游标的方法试试

--游标
use sybase
create table tb
(
Id int,
value varchar(50),
)
insert into tb values('1','aa')
insert into tb values('1','bb')
insert into tb values('2','aaa')
insert into tb values('2','bbb')
insert into tb values('2','ccc')
go
declare @AA varchar(50)
declare @BB varchar(50)
declare @CC varchar(50)

declare my_cursor cursor for select value from tb
open my_cursor
fetch next from my_cursor into @AA
fetch next from my_cursor into @BB
select Id ,value=(@AA+','+@BB ) from tb where value=@BB
fetch next from my_cursor into @AA
fetch next from my_cursor into @BB
fetch next from my_cursor into @CC
select Id,value=(@AA+','+@BB+','+@CC) from tb where value=@AA
close my_cursor
deallocate my_cursor
drop table tb
