Guys, this problem is solved. Below is the code I found.Thanks
Create
Table SRC

(

no
int identity(1,1) ,

id
int,

comment
varchar(20)

)

Insert
Into SRC Values (123,'I am Joe')

Insert
Into SRC Values (123,' I am programmer')

Insert
Into SRC Values (124,'I am Wang')

Insert
Into SRC Values (124,' I am programmer')

Insert
Into SRC Values (124,'I like Criket')

Create
Table DEST

(

id
int,

seq
int,

comment
varchar(20)

)

Declare
@seq int

Declare
@id int

Declare
@comment varchar(20)

Declare
@seqmax int

Declare
@nomax int

Declare
@no int

Set
@id = 123

Set
@seq = 1

While
(@id<=124)

Begin

Select @seqmax = count(*) from SRC Where id = @id

Select @no = min(no) from SRC Where id = @id

Select @nomax =max(no) from SRC Where id = @id

Select @id =id,@comment=comment From SRC Where id = @id and no =@no

While(@no<=@nomax)

Begin

Insert Into DEST

Select @id,@seq,comment From SRC Where id = @id and no =@no

Set @no = @no + 1

Set @seq =@seq + 1

End

Set @seq = 1

Set @id =@id +1

End

Select
* From DEST

Do you have any other column in your table with unique values?

You can also do

select id, (select count(*) from src where id=t.id and no<=t.no) as no, comment
from src t order by 1,2
