SQL LEAD -Running total

Is there any better way to get the position value without creating temporary table?
Id	value	character_Len	Position
1	ab	         2	               2
2	1	        2	               4
3	34	       2	               6
4	@	       1	                7
5	00100	 5	             12

create table #temp2 (id int , [character] varchar(100), position int)
insert into #temp2(id,character,position)
select a.Id, a.item, sum(b.lens) -1 as position
from #t1 a cross join #t2 b
where b.Id <= a.Id
group by a.Id, a.item
order by sum(b.lens)
#t1 holds all information expect position column.

Vitor MontalvãoMSSQL Senior EngineerCommented:
Well, if SQL Server 2005 or higher then you can try this:
select a.Id, a.item, sum(b.lens) -1 as Result
	RANK() OVER (PARTITION BY a.id, a.item ORDER BY sum(b.lens) -1  DESC) AS Position
from #t1 a 
	cross join #t2 b
where b.Id <= a.Id
group by a.Id, a.item
order by position
