TSQL 2008 Running total with previous months & years - tsql

Question

I'm trying to get the Running total from the values from the previous months. And if the month is january I would like to get the total from the previous year and so forth.
I hope someone can help.
WITH CTE AS (SELECT COUNT(LZP.pv_zaaknummer) AS [Aantal LZP]
, YEAR(LZP.lzp_actief_vanaf) AS Jaar
, MONTH(LZP.lzp_actief_vanaf) AS Maand
FROM dm.crm_LZP_Vn_zaaktype_leefzorgplan_registrerenExtensionBase_hist AS LZP
WHERE LZP.LZP_actief_tot_LDTS > GETDATE()
GROUP BY YEAR(LZP.lzp_actief_vanaf)
, MONTH(LZP.lzp_actief_vanaf)
)
SELECT a.Jaar
, a.Maand
, a.[Aantal LZP]
, (
SELECT SUM(b.[Aantal LZP])
FROM CTE AS b
WHERE b.Jaar <= a.Jaar
) AS [Running Total 1]
, (
SELECT SUM(b.[Aantal LZP])
FROM CTE AS b
WHERE b.Jaar <= a.Jaar
AND b.Maand <= a.Maand
) AS [Running Total 2]
FROM CTE AS a
ORDER BY a.Jaar, a.Maand;
Results as of now, I'm getting the Totals per year and then the running totals per year:
Jaar Maand Aantal LZP Running Total 1 Running Total 2
2014 4 11 661 11
2014 5 52 661 63

Answer 1

you could do it without subquery try
....................)
SELECT a.Jaar
, a.Maand
, a.[Aantal LZP],SUM([Aantal LZP]) over (order by jaar) [Running Total 1]
, SUM([Aantal LZP]) over (partition by jaar order by maand) [Running Total 2],
SUM([Aantal LZP]) over ( order by jaar,maand) [Running Total 3]
FROM CTE AS a
ORDER BY a.Jaar, a.Maand;
old version
SELECT a.Jaar
, a.Maand
, a.[Aantal LZP],(SELECT SUM(b.[Aantal LZP])
FROM CTE AS b
WHERE b.Jaar <= a.Jaar
) [Running Total 1],
(SELECT SUM(b.[Aantal LZP])
FROM CTE AS b
WHERE b.Jaar <= a.Jaar and Maand<=a.Maand
) [Running Total 2]
, (SELECT SUM(b.[Aantal LZP])
FROM CTE AS b
WHERE dateadd(year,jaar-1900,dateadd(month,maand-1,0)) <= dateadd(year,a.jaar-1900,dateadd(month,a.maand-1,0))
) [Running Total 3]
FROM CTE AS a
ORDER BY a.Jaar, a.Maand;

Answer 2

Found the Solution but now I must find to integrate it so it responds to my reportparameters Jaar and Maand
DECLARE #SalesTbl TABLE (Jaar int, Maand int, Aantal int, RunningTotal int)
DECLARE #Jaar int,
#Maand int,
#Aantal int,
#RunningTotal int
SET #RunningTotal = 0
DECLARE rt_cursor CURSOR
FOR
WITH CTE AS
(SELECT COUNT(LZP.pv_zaaknummer) AS [Aantal LZP]
, YEAR(LZP.lzp_actief_vanaf) AS Jaar
, MONTH(LZP.lzp_actief_vanaf) AS Maand
FROM dm.crm_LZP_Vn_zaaktype_leefzorgplan_registrerenExtensionBase_hist AS LZP
WHERE LZP.LZP_actief_tot_LDTS > GETDATE()
GROUP BY LZP.lzp_actief_vanaf
)
SELECT A.Jaar, A.Maand, SUM(A.[Aantal LZP])
FROM CTE AS A
GROUP BY Jaar, Maand
ORDER BY A.Jaar, A.Maand
OPEN rt_cursor
FETCH NEXT FROM rt_cursor INTO #Jaar, #Maand, #Aantal
WHILE ##FETCH_STATUS = 0
BEGIN
SET #RunningTotal = #RunningTotal + #Aantal
INSERT #SalesTbl VALUES (#Jaar, #Maand,#Aantal,#RunningTotal)
FETCH NEXT FROM rt_cursor INTO #Jaar, #Maand, #Aantal
END
CLOSE rt_cursor
DEALLOCATE rt_cursor
SELECT * FROM #SalesTbl
