SQLでの割り当て数C＃

Question

問題があり、ヘルプやアイデア、または次の問題の解決策を見つけるのに役立つ検索キーワードがあります。 2つのテーブルがあり、1つにインポート情報、1にエクスポート情報が含まれています。

tblImport (iCode, ComponentCode, iTotal) 
tblExport (eCode, ProductCode, ComponentCode, eNum) 

Idie allocation quantity two tables

要件：私は、各componentCode の列挙を有するECODEを含むテーブルを作成する必要があり、その場合和（ENUM）= ITOTAL。

カラム3は、そのカラム（5）= iTotal - （iCode、eCodeによるパーティションの合計）で求められる結果です。条件は、各セット（iCode、eCode、ComponentCode）が1回だけ表示されることです。つまり、私が割り当てた行は無視されます。 ここでの問題は、tblImportがComponentCode経由でtblExportに参加すると、これは真ではなく、重複する行が存在することです。

これをSQLで実装できますか？もしそうなら、それを技術的に可能にすることを私に教えてください。 何もない場合は、SQLまたはC＃で実装する方法を教えてください。 Google翻訳者から翻訳 ありがとう皆さん。

私はそれをしました！

CREATE TABLE Orders 
    ([OrderID] int, [Item] varchar(3), [Quantity] int) 
; 

INSERT INTO Orders 
    ([OrderID], [Item], [Quantity]) 
VALUES 
    (1, 'pen', 80), 
    (2, 'pen', 30), 
    (3, 'pen', 25) 
; 

CREATE TABLE Inventory 
    ([InvID] int, [Lot] varchar(3), [Item] varchar(3), [Quantity] int) 
; 

INSERT INTO Inventory 
    ([InvID], [Lot], [Item], [Quantity]) 
VALUES 
    (1, '001', 'pen', 100), 
    (2, '002', 'pen', 20), 
    (3, '003', 'pen', 30) 
; 



INSERT INTO dbo.Inventory VALUES (4, '001','Ink',50) 
INSERT INTO dbo.Inventory VALUES (5, '002','Ink',50) 
INSERT INTO Orders VALUES (4, 'Ink', 30) 
INSERT INTO Orders VALUES (5, 'Ink', 60) 



    WITH CTE_Orders AS 
(
    SELECT *, ROW_NUMBER() OVER (PARTITION BY Item ORDER BY OrderID) AS RN 
    FROM dbo.Orders 
) 
, CTE_Inventory AS 
(
    SELECT *, ROW_NUMBER() OVER (PARTITION BY Item ORDER BY InvID) AS RN 
    FROM dbo.Inventory 
) 
, CTE AS 
(
    SELECT o.RN AS OrderRN, 
      inv.RN AS InvRN, 
      OrderID , 
      o.Item , 
      o.Quantity AS OrderedQuantity , 
      InvID , 
      Lot , 
      inv.Quantity AS InvQuantity, 
      CASE WHEN inv.Quantity - o.Quantity > 0 THEN o.Quantity ELSE inv.Quantity END AS ServedQuantity , 
      CASE WHEN inv.Quantity - o.Quantity > 0 THEN 0 ELSE o.Quantity - inv.Quantity END AS LeftToServe, 
      CASE WHEN inv.Quantity - o.Quantity > 0 THEN inv.Quantity - o.Quantity ELSE 0 END AS LeftInLot 
    FROM CTE_Orders o 
    INNER JOIN CTE_Inventory inv ON o.Item = inv.Item 
    --WHERE OrderID = 1 AND InvID = 1 
    WHERE o.RN =1 AND inv.RN = 1 
    UNION ALL 
    SELECT CASE WHEN c1.LeftInLot <=0 THEN c1.OrderRN ELSE c2.OrderRN END AS OrderRN 
      ,CASE WHEN c1.LeftInLot <=0 THEN c2.InvRN ELSE c1.InvRN END AS InvRN 
      ,CASE WHEN c1.LeftInLot <=0 THEN c1.OrderID ELSE c2.OrderID END AS OrderID 
      ,CASE WHEN c1.LeftInLot <=0 THEN c1.Item ELSE c2.Item END AS Item 
      ,CASE WHEN c1.LeftInLot <=0 THEN c1.OrderedQuantity ELSE c2.OrderedQuantity END AS OrderedQuantity 
      ,CASE WHEN c1.LeftInLot <=0 THEN c2.InvID ELSE c1.InvID END AS InvID 
      ,CASE WHEN c1.LeftInLot <=0 THEN c2.Lot ELSE c1.Lot END AS Lot 
      ,CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END AS InvQuantity 
      ,CASE WHEN CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END - CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END > 0 
        THEN CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END 
        ELSE CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END 
      END AS ServedQuantity 
      ,CASE WHEN CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END - CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END > 0 
        THEN 0 
        ELSE CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END - CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END 
      END AS LeftToServe 
      ,CASE WHEN CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END - CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END > 0 
        THEN CASE WHEN c1.LeftInLot <=0 THEN c2.InvQuantity ELSE c1.LeftInLot END - CASE WHEN c1.LeftInLot <=0 THEN c1.LeftToServe ELSE c2.OrderedQuantity END 
        ELSE 0 
      END AS LeftInLot 
    FROM CTE c1 
    INNER JOIN 
    (
     SELECT o2.RN AS OrderRN, 
       inv2.RN AS InvRN, 
       InvID , 
       Lot , 
       inv2.Item , 
       inv2.Quantity AS InvQuantity, 
       OrderID , 
       o2.Quantity AS OrderedQuantity 
     FROM 
     CTE_Inventory inv2 
     INNER JOIN CTE_Orders o2 ON inv2.Item = o2.Item 
    ) c2 
    ON c1.Item = c2.Item AND 
    ((c2.InvRN = c1.InvRN + 1 AND c2.OrderRN = c1.OrderRN AND c1.LeftInLot <= 0) OR (c2.OrderRN = c1.OrderRN + 1 AND c2.InvRN = c1.InvRN AND c1.LeftInLot>0)) 

) 
SELECT * FROM CTE 
ORDER BY item,OrderID 

これは機能します。

Tks！
