SQL Server: извлечение цикла XML

Question

У меня есть два отдельных XML-файла, которые находятся в таблице dbo.XMLwithOpenXML в SQL Server, с Id в качестве первичного ключа.

Я пытаюсь извлечь каждый XML-документ в таблицы, которые я могу успешно сделать,однако я хотел бы пройтись по моим двум XML и извлечь данные таким образом.Мои текущие попытки только позволяют мне извлекать второй XML-документ и не извлекают ничего из первого.

declare
     @XMLData XML,
     @TableName Varchar(255) = 'XML_Tables',
     @ServerName varchar(255) = 'Census',
     @Id int,
     @locationiterator int = 1

Select @XMLData = XMLData from XMLwithOpenXML;

Declare ApplicationCursor cursor for
    select Id 
    from [dbo].[XMLwithOpenXML]
    where LoadedDateTime > '2019-02-20 16:07:57.227'

open ApplicationCursor

Truncate Table [dbo].[DeliveryDetails]
Truncate Table [dbo].[Items]

fetch next from ApplicationCursor into @Id

while @@FETCH_STATUS = 0
begin
    select @XMLData

    Output

----------------------------------------------------------------------------------------------------------
--Delivery Details--

insert into [dbo].[DeliveryDetails]
(
     [PurchaseOrder]
    ,[ShippingType] 
    ,[Street] 
    ,[City] 
    ,[State] 
    ,[Zip] 
    ,[Country] 
    ,Comments
)



SELECT pd.value('(@PurchaseOrderNumber)[1]','nvarchar(max)') As PurchaseOrder
,pd.value('(@OrderDate)[1]','nvarchar(max)') As OrderDate
,pd.value('(Address/@Type)[1]','nvarchar(max)') as DeliveryType
,pd.value('(Address/Name/text())[1]','nvarchar(max)') as test
,pd.value('(Address/Street/text())[1]','nvarchar(max)') AS Street
,pd.value('(Address/City/text())[1]','nvarchar(max)') as City
,pd.value('(Items//Item/@PartNumber)[1]','nvarchar(max)') as PartNumber
,pd.value('(DeliveryNotes/text())[1]','nvarchar(max)') as DeliveryNotes
from @xmlData.nodes('/PurchaseOrders/PurchaseOrder') as i(pd);

SET @locationiterator = @locationiterator + 1
        END

----------------------------------------------------------------------------------
--Item Details--


insert into [dbo].[Items]
(
PurchaseOrder,Item, ProductName, Quantity, USPrice
)

Select 
 Rec.value('../../@PurchaseOrderNumber[1]','nvarchar(max)') as PurchaseOrderNumber
,Rec.value('@PartNumber[1]','nvarchar(max)') As ItemNumber
,Rec.value('ProductName[1]','nvarchar(max)') as ProductName
,Rec.value('Quantity[1]','nvarchar(max)') as Quantity
,Rec.value('USPrice[1]','nvarchar(max)') as USPrice


from @xmlData.nodes('//PurchaseOrders/PurchaseOrder/Items/Item') as x(Rec);
--------------------------------------------------------------------------
fetch next from ApplicationCursor
into @Id


End

Close ApplicationCursor
Deallocate ApplicationCursor
