Stop sum when value reached - sql-server

Question

Assume Table1:
|PaymentID|CashAmount|
----------------------
| P1 | 3000|
| P2 | 5000|
| P3 | 8000|
| P4 | 700|
| P5 | 5500|
| P6 | 1900|
If I want to sum of CashAmount to be 'at least' 9000. PaymentID order should be the same.
Expected Result:
|PaymentID|CashAmount|
----------------------
| P1 | 3000|
| P2 | 5000|
| P3 | 8000|
If I want to sum of CashAmount to be 'at least' 4000. PaymentID order should be the same.
Expected Result:
|PaymentID|CashAmount|
----------------------
| P1 | 3000|
| P2 | 5000|
I had a look at limiting the rows to where the sum a column equals a certain value in MySQL. But the accepted answer is not working with MSSQL and is not exactly what I'm looking for. Most of the answers there I've tested and they return only rows that the total amount is less than, not at least specific value.

Answer 1

SQL Server 2005 and Later
SELECT *
FROM TableName t
CROSS APPLY (SELECT SUM(Amount)
FROM TableName
WHERE [Date] <= t.[DATE]) c(AmtSum)
WHERE AmtSum <= 13
SQL Server 2012 and Later
SELECT *
FROM (
SELECT *
,SUM(Amount) OVER (ORDER BY [Date], Amount) AmtSum
FROM TableName
)t
WHERE AmtSum <= 13

Answer 2

According to your new input I changed my approach slightly. Hope this is what you need...
EDIT: Here's the version with SUM(x) OVER(...):
DECLARE #payment TABLE(PaymentID VARCHAR(10),CashAmount INT);
INSERT INTO #payment VALUES
('P1',3000)
,('P2',5000)
,('P3',8000)
,('P4',700)
,('P5',5500)
,('P6',1900);
DECLARE #myMinToReach INT=9000;
WITH SortedPayment AS
(
SELECT ROW_NUMBER() OVER(ORDER BY PaymentID) AS inx
,SUM(CashAmount) OVER(ORDER BY PaymentID) AS Summa
FROM #payment
)
SELECT * FROM SortedPayment
WHERE inx<=(SELECT TOP 1 x.inx
FROM SortedPayment AS x
WHERE Summa>#myMinToReach
ORDER BY Summa ASC);
And that's the old version for SQL-Server < 2012
DECLARE #payment TABLE(PaymentID VARCHAR(10),CashAmount INT);
INSERT INTO #payment VALUES
('P1',3000)
,('P2',5000)
,('P3',8000)
,('P4',700)
,('P5',5500)
,('P6',1900);
DECLARE #myMinToReach INT=4000;
WITH SortedPayment AS
(
SELECT ROW_NUMBER() OVER(ORDER BY PaymentID) AS inx,*
FROM #payment
)
,Accumulated AS
(
SELECT tbl.*
FROM
(
SELECT SortedPayment.*
,Accumulated.Summa
FROM SortedPayment
CROSS APPLY
(
SELECT SUM(ps2.CashAmount) AS Summa
FROM SortedPayment AS ps2
WHERE ps2.inx<=SortedPayment.inx
) AS Accumulated
) AS tbl
)
SELECT * FROM Accumulated
WHERE inx<=(SELECT TOP 1 x.inx
FROM Accumulated AS x
WHERE Summa>#myMinToReach
ORDER BY Summa ASC);

Answer 3

declare #s int;
update table set rc=row_count() over (order by date)
declare #i int;
set #i=1;
while #s<=12 or #i<100000
set #s=#s+(select amount from table where rc=#i+1);
set #i=#i+1;
end
// #s has at least 12
