Combining records

Hi,
Can anybody please tell how can I combing all records in field into one field.
For example

If my table is like

Final
_______
aaa
bbb
ccc
ddd


and i want result as

final1
_____
aaabbbcccddd


I do not want to use cursors for this. Please let me know if somebody knows the answer

Thanks

If total string length is less than 8000 characters then you can do

declare @result varchar(8000)

set @result=''

select @result=@result+final
from mytable

print @result

Thanks for your help.
