There's no running total to be had because the ID you're using is the same for everything. If you had an identity column as well, it'd be different:

declare @t table (
	id int identity,
	ptid varchar(100),
	actual decimal(10,2))
	
insert into @t (ptid,actual)
select '20-3199122', 22.16
union select '20-3199122', 59.12
union select '20-3199122', 11.81
union select '20-3199122', 53.22
union select '20-3199122', 121.24

select id,ptid,actual,(select SUM(actual) from @t t1 where t1.ptid=t.ptid and t1.id <= t.id) as 'RunningTotal'
from @t t
where ptid='20-3199122'

actually i thought of a way you could work this with your current structure:

with rownums as (
	select PtID, BRSVDT, ccActualBrAmt, ROW_NUMBER() over (partition by PtID, order by PtID) as 'rownum' from dbo.VW_HBRVDTFL)
	
SELECT PtID, BRSVDT, ccActualBrAmt,
                   (SELECT SUM(ccActualBrAmt) AS Expr1
                    FROM   rownums
                    WHERE PtID = t.PtID and (rownum <= t.rownum)) AS RunningTotal
FROM  rownums AS t
WHERE (PtID = '20-3199122')

Open in new window


with that, you could even remove the final WHERE PtID = '...' and it should give running totals for each separate PtID i believe, based on the ordering in the table.

ROW_NUMBER is not implemented in SQL Server 2000. There is no other way unless there is a primary key or unique index in the table.

That is correct, apologies, forgot this was 2000. The common table expression wouldn't work either.

We can use field  BRSVDT and ccActualBRAmt as running total

SELECT PtID, BRSVDT, ccActualBrAmt,
    (SELECT SUM(ccActualBrAmt) AS Expr1
      FROM   dbo.VW_HBRVDTFL a
      WHERE (a.PtID = t.PtID AND  a.BRSVDT <= t.BRSVDT AND a.ccActualBrAmt <= t.ccActualBrAmt))
       AS RunningTotal
FROM  dbo.VW_HBRVDTFL AS t
WHERE (PtID = '20-3199122')

I suspect the author has left the building or just does not want to provide any further feedback.
