Question

表： StoreItems

表： StockInOutType

表： Store

我想计算股票进入时间和结束时间。

我的查询

SELECT  
    ItemName, DateTime [Entry Time], Qty 
FROM 
    Store 
JOIN
    StockInOutType ON Store.StockInOutType = StockInOutType.Id
JOIN
    StoreItems ON Store.ItemID = StoreItems.ItemID
WHERE 
    Store.StockInOutType = 4 
    AND StoreItems.ItemID = 25 
    AND SessionID = 735721

StockInOuttype 4和6不是销售。

数据（Store表）

Answer 1

最大的问题是，如果购买了“购买者”，您希望发生什么？活动时仍有库存。由于您没有来自“销售”的链接。对股票这种行为很难跟踪。假设这没有发生/您不关心这种情况，解决方案是简单地选择下一个库存作为书挡如下

SELECT ItemName, 
    DateTime AS [Entry Time], 
    Qty, 
    CASE WHEN LEAD(Store.DateTime) OVER (ORDER BY Store.DateTime) IS NOT NULL 
         THEN (SELECT MAX(DateTime) 
               FROM Store s2 
               WHERE s2.StockInOutType = 2 AND 
                     s2.DateTime < LEAD(Store.DateTime) OVER (ORDER BY Store.DateTime)) 
    ELSE NULL END AS EndingTime
FROM 
    Store 
WHERE 
    Store.StockInOutType = 4 
AND Store.ItemID = 25 
ORDER BY DateTime

您可以通过计算每个购买交易的起点和出口点的序列号来计算FIFO模式中的库存周转率。

这可以通过使用运行总计（-- Calculate serials for the orders and inventory receipts -- put them in temp tables to make them easier to work with. This could -- also be done with a view or a CTE CREATE TABLE #Orders ( TxnID INT NOT NULL, TxnDate DATETIME NOT NULL, ItemID INT NOT NULL, Qty INT NOT NULL, ConsumptionStartSerial INT, ConsumptionEndSerial INT ); INSERT INTO #Orders (TxnID, TxnDate, ItemID, Qty, ConsumptionStartSerial, ConsumptionEndSerial) SELECT TxnID, TxnDate, ItemID, Qty, ConsumptionEndSerial - Qty as ConsumptionStartSerial, ConsumptionEndSerial FROM ( SELECT TxnID, TxnDate, ItemID, ChangeQty * -1 as Qty, SUM(ChangeQty) OVER(PARTITION BY ItemID ORDER BY TxnID ROWS UNBOUNDED PRECEDING) * -1 as ConsumptionEndSerial FROM ItemTransactions WHERE ChangeQty < 0 ) as inr; SELECT * FROM #Orders; CREATE TABLE #InventoryReceipts ( TxnID INT NOT NULL, ItemID INT NOT NULL, Qty INT NOT NULL, StockStartSerial INT, StockEndSerial INT ); INSERT INTO #InventoryReceipts (TxnID, ItemID, Qty, StockStartSerial, StockEndSerial) SELECT TxnID, ItemID, Qty, StockEndSerial - Qty as StockStartSerial, StockEndSerial FROM ( SELECT TxnID, ItemID, ChangeQty as Qty, SUM(ChangeQty) OVER(PARTITION BY ItemID ORDER BY TxnID ROWS UNBOUNDED PRECEDING) as StockEndSerial FROM ItemTransactions WHERE ChangeQty > 0 ) as inr; SELECT * FROM #InventoryReceipts; -- Stock turnover -- Find the first and last order for each inventory receipt -- Calculate the days on shelf based off of the first and last -- order which uses the product SELECT inr.TxnID as StockTxn, txn.TxnDate, txn.[Description], inr.ItemID, inr.Qty, i.Name, inr.StockOpenedTxnID, inr.StockFinishedTxnID, DATEDIFF(day, txn.TxnDate, oStart.TxnDate) as DaysToOpen, DATEDIFF(day, txn.TxnDate, oEnd.TxnDate) as DaysToConsumed FROM ( SELECT ir.TxnID, ir.ItemID, ir.Qty, MAX(oStart.TxnID) as StockOpenedTxnID, MIN(oEnd.TxnID) as StockFinishedTxnID FROM #InventoryReceipts ir LEFT OUTER JOIN #Orders oStart on ir.ItemID = oStart.ItemID and ir.StockStartSerial >= oStart.ConsumptionStartSerial LEFT OUTER JOIN #Orders oEnd on ir.ItemID = oEnd.ItemID and ir.StockEndSerial < oEnd.ConsumptionEndSerial GROUP BY ir.TxnID, ir.ItemID, ir.Qty ) as inr INNER JOIN Items i on inr.ItemID = i.ItemID INNER JOIN ItemTransactions txn on inr.TxnID = txn.TxnID LEFT OUTER JOIN #Orders oStart ON inr.StockOpenedTxnID = oStart.TxnID LEFT OUTER JOIN #Orders oEnd ON inr.StockFinishedTxnID = oEnd.TxnID DROP TABLE #InventoryReceipts; DROP TABLE #Orders;）

在SQL Server中完成

示例（my post）：

| StockTxn |                   TxnDate |               Description | ItemID | Qty |    Name | StockOpenedTxnID | StockFinishedTxnID | DaysToOpen | DaysToConsumed |
|----------|---------------------------|---------------------------|--------|-----|---------|------------------|--------------------|------------|----------------|
|        1 | January, 01 2015 00:00:00 | Received 10 from supplier |      1 |  10 | Chicken |                3 |                  6 |          8 |             12 |
|        2 | January, 02 2015 00:00:00 |  Received 5 from supplier |      2 |   5 |    Beef |                5 |             (null) |          9 |         (null) |
|        4 | January, 11 2015 00:00:00 |  Received 5 from supplier |      1 |   5 | Chicken |                6 |             (null) |          2 |         (null) |
