我有一个xml文件，如下所示：

     <?xml version="1.0" encoding="UTF-8" ?> 
- <DeliveryPackage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" VersionNo="Q214" CreationTime="2014-04-16T02:29:04.000000000" MapVersion="IND 14 2 00" Language_Code_Desc="../DEFINITIONS/language.xml" Country_Code_Desc="../DEFINITIONS/country.xml" Supplier_Code_Desc="../DEFINITIONS/supplier.xml" XY_Type="WGS84" Category_Code_Desc="../DEFINITIONS/category.xml" Char_Set="UTF-8" UpdateType="BulkUpdate" Coverage="IND" Category="7997">

我想在SQL Server表中插入所有属性，从操作到编号开始。我已经在第1列的三列中进行过尝试，如下所示：首先，我将完整的xml文件放在表“数据”中，然后使用以下代码：

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)

SELECT @XML = XMLData FROM data

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML


SELECT [Action],SupplierID,Poi_Entity_Id
FROM OPENXML(@hDoc, 'POI')
WITH 
(
[Action] [varchar](50) '@Action',
SupplierID [int] '@SupplierID',
Poi_Entity_Id [varchar](100) 'Poi_Entity_Id'
)


EXEC sp_xml_removedocument @hDoc
GO

但是在所有列中获取空值...我不想手动执行此操作，因为我的XML中有1000条记录。请帮忙

您的数据存储在元素中，而不是属性中，并且您忘记将DeliveryPackage节点添加到xpath中：

select
    T.C.value('Action[1]', 'nvarchar(128)') as [Action],
    T.C.value('SupplierID[1]', 'nvarchar(128)') as SupplierID,
    T.C.value('(Identity/POI_Entity_ID)[1]', 'nvarchar(128)') as POI_Entity_ID
from @XML.nodes('DeliveryPackage/POI') as T(C)

或者，如果您想使用openxml：

declare @hDoc int

exec dbo.sp_xml_preparedocument @hDoc output, @XML

select
    [Action],SupplierID,Poi_Entity_Id
from openxml(@hDoc, 'DeliveryPackage/POI')
with 
(
    [Action] [varchar](50) 'Action[1]',
    SupplierID [int] 'SupplierID[1]',
    Poi_Entity_Id [varchar](100) '(Identity/POI_Entity_ID)[1]'
)

exec dbo.sp_xml_removedocument @hDoc
