Pivot和sqlserver中的一些问题

帮助我获得这段代码，它输出良好，我可以看到在所选日期谁在项目中拥有仓库或行程，但我还想在Beg Bal不是0时输出，即使在所选日期仓库和行程表中没有发生任何事情

这是密码

Declare @to DATETIME
Set @to = '2016-11-15'

;WITH tTable AS(

Select i.ItemCode,Goods.Description,wQty,tQty,TripName,

Select * From tTable

Pivot

预期产出为：

ItemCode Beg Bal End Bal PRODN ...... SMK4 
C900     270     272     64    ...... 50 

ItemCode Beg Bal End Bal PRODN ...... SMK4

C900     270     272     64    ...... 50

我猜您需要一个到子查询传递的左连接，而不是内部连接

我不确定为什么您提供了两个pivot片段，它们都不包括在上面的查询中

我不得不说，您在tTable的select子句中使用了几个相关的子查询，如下所示：

, (
      SELECT
            ISNULL(SUM(fgd.Quantity), 0)
      FROM FinishedGoodsDetails fgd
      LEFT JOIN FinishedGoods fg ON fg.DeliveryReceiptNumber = fgd.DeliveryReceiptNumber
      LEFT JOIN Warehouse w ON w.WarehouseID = fg.WarehouseID
      WHERE fg.CreatedOn < @to
      AND fgd.ItemID = i.ItemID
      AND fg.Status IN ('X', 'C')
  )

---

通常，这种类型的相关子查询是一个性能问题，在SQL Server中，将这种类型的逻辑移动到交叉应用或外部应用中可能会带来好处。

请编辑您的问题：1。在代码中添加缩进。2.不要在评论中发布附加数据在问题中发布

, (
      SELECT
            ISNULL(SUM(fgd.Quantity), 0)
      FROM FinishedGoodsDetails fgd
      LEFT JOIN FinishedGoods fg ON fg.DeliveryReceiptNumber = fgd.DeliveryReceiptNumber
      LEFT JOIN Warehouse w ON w.WarehouseID = fg.WarehouseID
      WHERE fg.CreatedOn < @to
      AND fgd.ItemID = i.ItemID
      AND fg.Status IN ('X', 'C')
  )
