Sql server 在表中添加XML文件的不同节点/标记

我正在尝试解析包含如下数据的XML：

<Orders>
  <Order>
  <OrderHeader Shop="7894" ClientNo="45678" ClientDescr="Here Client Description" OrderID="7898" OrderDate="20160505" DelivDate="20160606" Comment="" Pricelevel="myLevel" Total="124"/>   
  <ItemSold Product="63636" ItemText="New item" Qty="6" Delivery="" Price="24" />
  <ItemSold Product="4564" ItemText="Item Text here" Qty="6" Delivery="" Price="456" />
  <ItemRefund Product="555" ItemText="Item Text here" ItemType="B" Qty="1" Delivery="" Price="20" />
  </Order>
</Orders>

对于订单标题，我可能需要另一个表，然后用它创建一个外键。

您可以使用

XML和所有表定义

DECLARE @xml XML = N'<Orders>
  <Order>
  <OrderHeader Shop="7894" ClientNo="45678" ClientDescr="Here Client Description" OrderID="7898" OrderDate="20160505" DelivDate="20160606" Comment="" Pricelevel="myLevel" Total="124"/>   
  <ItemSold Product="63636" ItemText="New item" Qty="6" Delivery="" Price="24" />
  <ItemSold Product="4564" ItemText="Item Text here" Qty="6" Delivery="" Price="456" />
  <ItemRefund Product="555" ItemText="Item Text here" ItemType="B" Qty="1" Delivery="" Price="20" />
  </Order>
  <Order>
  <OrderHeader Shop="7894" ClientNo="45678" ClientDescr="Here Client Description" OrderID="8000" OrderDate="20160505" DelivDate="20160606" Comment="" Pricelevel="myLevel" Total="124"/>

  </Order>
</Orders>'
