我已经研究过，并没有想出任何人做这样的事情。我愿意接受建议。现在我正在尝试加载下面描述的表格。
CREATE TABLE [Course].[Navigation](
[NavigationId] [int] IDENTITY(1,1) NOT NULL,
[ParentID] [int],
[ChildID] [int],
[Type] [varchar](100) NULL,
[Label] [int] NULL,
[Id] [varchar](100) NULL )
代表课程的导航图。
我正在尝试加载的XML是：

查询将首先使用连接的序列（thx to John Cappelletti！）来获取原始订单，其次这可以用作id和parentId
WITH recCTE AS
(
SELECT 1 AS Lvl
,nc.value(N'@label','nvarchar(max)') AS Label
,nc.value(N'@id','nvarchar(max)') AS id
,CAST(REPLACE(STR(ROW_NUMBER() OVER(ORDER BY (SELECT NULL)),3),' ','0') AS VARCHAR(MAX)) AS Seqnc
,CAST(NULL AS VARCHAR(MAX)) AS ParentSeqnc
,nc.query('./content') AS Deeper
FROM @xml.nodes(N'/navigation/content') AS A(nc)
UNION ALL
SELECT recCTE.Lvl+1
,nc2.value(N'@label','nvarchar(max)') AS Label
,nc2.value(N'@id','nvarchar(max)') AS id
,recCTE.Seqnc+REPLACE(STR(ROW_NUMBER() OVER(ORDER BY (SELECT NULL)),3),' ','0')
,recCTE.Seqnc
,nc2.query('./content') AS Deeper
FROM recCTE
CROSS APPLY recCTE.Deeper.nodes(N'content') AS A(nc2)
)
SELECT Lvl
,id

ORDER BY Seqnc;
