特定の値に等しい特定の列の合計で行をグループ化

実行中の合計が計算されたソース テーブルに適用される「期日」の境界を定義するヘルパー テーブルを使用して、各実行中の合計額と「期日」の境界との交点を計算できます。

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)
  

 注意:SUM(...) Over (Order By ... Rows Unbounded Preceding) および IIF(...) SQL Server 2012+ でのみ使用できます。サブクエリを使用して SQL Server 2008 でも同じことができますが、効率は大幅に低下します:
