Question

我有以下xml。如果你运行它，你将有3个网格结果。我正在努力处理最后的网格结果，因为我需要网格结果来获得相关的关联。换句话说，我希望网格结果＃3中的网格结果＃2中有相关的RowID。我怎样才能做到这一点？最终，网格结果＃2将插入到具有名为SalesOrderID的主键的永久表中。网格结果＃3将以SalesOrderID作为外键进入另一个表。

非常感谢！

DECLARE @xml XML;

 drop table #tmpDetails

将Lots的XML存储在#tmpDetails.Lots

中

SELECT IDENTITY(int, 1,1) AS RowID
 ,doc.col.value('SalesOrderNumber[1]', 'varchar(50)') SalesOrderNumber
 ,doc.col.value('ItemId[1]', 'varchar(50)') ItemId
 ,doc.col.value('IsBackOrdered[1]', 'varchar(50)') IsBackOrdered
 ,doc.col.value('TrackingNumber[1]', 'varchar(50)') TrackingNumber
 ,doc.col.query('Lots') Lots
 INTO #tmpDetails
FROM @xml.nodes('/ShipmentConfirmationMessage/ShippedItems/ShipmentConfirmationLine') doc(col)

使用#tmpDetails在第三个查询中使用CROSS APPLY来粉碎Lots中的XML。

SELECT
  D.RowID
 ,doc.col.value('LotNumber[1]', 'varchar(50)') LotNumber
 ,doc.col.value('ExpiryDate[1]', 'datetime') ExpiryDate
 ,doc.col.value('Quantity[1]', 'decimal(13,5)') Quantity
FROM #tmpDetails D
  CROSS APPLY D.Lots.nodes('Lots/Lot') doc(col)

我怎样才能粉碎xml并保留关联？
