Kelompokkan Baris Dengan Jumlah Kolom Tertentu sama dengan Nilai Tertentu

Dengan tabel pembantu yang mendefinisikan batas "Utang" yang diterapkan pada tabel sumber dengan total berjalan yang dihitung, perpotongan dari setiap jumlah total yang berjalan dengan batas "Uang" dapat dihitung:

With Receipt As ( --< Sample source table
    Select * From (Values
        ('R1', 100),
        ('R2', 100),
        ('R3',  70),
        ('R4',  50),
        ('R5', 200)
    ) V (ReceiptNo, Amount)
), ReceiptWithTotal As ( --< Source table with Running Totals calculated
    Select *,
        SUM(Amount) Over (Order By ReceiptNo Rows Unbounded Preceding) - Amount As RunningTotalBefore,
        SUM(Amount) Over (Order By ReceiptNo Rows Unbounded Preceding) As RunningTotalAfter
    From Receipt
), Due As ( --< Helper table to define intervals (can be generated dynamically to cover any Total)
    Select * From (Values
        ('D1',   0, 100),
        ('D2', 100, 200),
        ('D3', 200, 300),
        ('D4', 300, 400),
        ('D5', 400, 500),
        ('D6', 500, 600)
    ) V (DueNo, AmountLow, AmountHigh)
)
Select DueNo, ReceiptNo,
    IIF(AmountHigh < RunningTotalAfter, AmountHigh, RunningTotalAfter) -
    IIF(AmountLow > RunningTotalBefore, AmountLow, RunningTotalBefore) As Amount
From Due
Inner Join ReceiptWithTotal On NOT (RunningTotalAfter <= AmountLow OR RunningTotalBefore >= AmountHigh)

Harap diperhatikan:SUM(...) Over (Order By ... Rows Unbounded Preceding) dan IIF(...) hanya tersedia di SQL Server 2012+. Hal yang sama dapat dilakukan pada SQL Server 2008 melalui sub-query meskipun kurang efisien:

With Receipt As ( --< Sample source table
    Select * From (Values
        ('R1', 100),
        ('R2', 100),
        ('R3',  70),
        ('R4',  50),
        ('R5', 200)
    ) V (ReceiptNo, Amount)
), ReceiptWithTotal As ( --< Source table with Running Totals calculated
    Select *, RunningTotalAfter - Amount As RunningTotalBefore
    From (
        Select *,
            (Select SUM(Amount) From Receipt B Where B.ReceiptNo <= A.ReceiptNo) As RunningTotalAfter
        From Receipt A
    ) A
), Due As ( --< Helper table to define intervals (can be generated dynamically to cover any Total)
    Select * From (Values
        ('D1',   0, 100),
        ('D2', 100, 200),
        ('D3', 200, 300),
        ('D4', 300, 400),
        ('D5', 400, 500),
        ('D6', 500, 600)
    ) V (DueNo, AmountLow, AmountHigh)
)
Select DueNo, ReceiptNo,
    CASE WHEN AmountHigh < RunningTotalAfter THEN AmountHigh ELSE RunningTotalAfter END -
    CASE WHEN AmountLow > RunningTotalBefore THEN AmountLow ELSE RunningTotalBefore END As Amount
From Due
Inner Join ReceiptWithTotal On NOT (RunningTotalAfter <= AmountLow OR RunningTotalBefore >= AmountHigh)
