distcode YTD (YTD Desc order)
D101 4000
D102 2000
D103 500

90% sales
ie., sum(YTD)*90% : 6500*90%=5850

I want to find out for 5850, count(distcode) contribution (ie.d how many distributor summing YTD comes to 5850 from YTD desc order ,we have to consider)

If i add 2 disttributor YTD then it comes near to 5850

result is count(Distcode)=2

is it possible write sql statement

DECLARE @tab TABLE(distcode VARCHAR(5), YTD INT)
INSERT INTO @tab VALUES('D101', 4000 ), ('D102', 2000), ('D103', 500)

SELECT COUNT(distcode)+1 DistCount
FROM (SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.distcode <= a.distcode) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a
)t
WHERE RunningTotal <= Sales

will not work always

see this sample data


distcode YTD (YTD Desc order)
D101 4000 
D102 1850
D103 300
D104 350

[code]
DECLARE @tab TABLE(distcode VARCHAR(5), YTD INT)
INSERT INTO @tab
--VALUES('D101', 4000 ), ('D102', 2000), ('D103', 500)
SELECT 'D103', 4000 UNION ALL
SELECT 'D102', 1850 UNION ALL
SELECT 'D101', 300 UNION ALL
SELECT 'D104', 350

SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a

;With CTE
AS
(
SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a
)
SELECT COUNT(distcode)+1 DistCount
FROM CTE t
WHERE RunningTotal < Sales[/code]

not again correct as its not considering the order of distcode


DECLARE @tab TABLE(distcode VARCHAR(5), YTD INT)
INSERT INTO @tab 
--VALUES('D101', 4000 ), ('D102', 2000), ('D103', 500)
SELECT 'D103', 4000  UNION ALL
SELECT 'D102', 1000 UNION ALL
SELECT 'D101', 900 UNION ALL
SELECT 'D106', 550 UNION ALL
SELECT 'D107', 200 UNION ALL
SELECT 'D105', 250 UNION ALL
SELECT 'D104',150


--Bandi solution
SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM  @tab a

;With CTE 
AS
(
	SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
		FROM  @tab a
)
SELECT COUNT(distcode)+1 DistCount
FROM CTE t
WHERE RunningTotal < Sales


--Visakh Solution

;With CTE 
AS
(
SELECT a.distcode, a.YTD,  0.9*SUM(YTD) OVER()  AS [90PC],
ROW_NUMBER() OVER (ORDER BY distcode) AS RN
		FROM  @tab a 
)

SELECT RN AS DistCount
FROM CTE c1
OUTER APPLY (SELECT SUM(YTD) AS  RunningTotal FROM CTE  WHERE RN < c1.RN) c2
WHERE COALESCE(RunningTotal,0)<= [90PC]
AND COALESCE(RunningTotal,0) + YTD > [90PC]

output
-----------------------------------------
distcode	YTD	RunningTotal	Sales
D103	4000	4000	6345.0
D102	1000	5000	6345.0
D101	900	5900	6345.0
D106	550	6450	6345.0
D107	200	6900	6345.0
D105	250	6700	6345.0
D104	150	7050	6345.0
