Sql server 将XML数据插入到表中

我需要将外部XML文件数据插入SQL Server表中。我尝试了下面的代码。但这会为所有列插入一条带有

NULL

值的记录

Declare @xml XML

Select @xml =
CONVERT(XML,bulkcolumn,2) FROM OPENROWSET(BULK 
'C:\Users\PC901\Downloads\Tags.xml',SINGLE_BLOB) AS X

SET ARITHABORT ON
TRUNCATE TABLE Tags

Insert into Tags
(
ID,WikiPostId,ExcerptPostId,Count,TagName
)

Select
P.value('ID[1]','BIGINT') AS ID,
P.value('WikiPostId[1]','BIGINT') AS WikiPostId,
P.value('ExcerptPostId[1]','BIGINT') AS ExcerptPostId,
P.value('Count[1]','BIGINT') AS Count,
P.value('TagName[1]','VARCHAR(100)') AS TagName
From @xml.nodes('/tags') PropertyFeed(P)

SELECT * FROM Tags

示例XML是

<?xml version="1.0" encoding="utf-8"?>
<tags>
   <row Id="1" TagName=".net" Count="283778" ExcerptPostId="3624959" WikiPostId="3607476" />
  <row Id="2" TagName="html" Count="826083" ExcerptPostId="3673183" WikiPostId="3673182" />
  <row Id="3" TagName="javascript" Count="1817846" ExcerptPostId="3624960" WikiPostId="3607052" />
  <row Id="4" TagName="css" Count="588062" ExcerptPostId="3644670" WikiPostId="3644669" />
  <row Id="5" TagName="php" Count="1286873" ExcerptPostId="3624936" WikiPostId="3607050" />
</tags>

给你：

declare @xml xml = '<?xml version="1.0" encoding="utf-8"?>
<tags>
  <row Id="1" TagName=".net" Count="283778" ExcerptPostId="3624959" WikiPostId="3607476" />
  <row Id="2" TagName="html" Count="826083" ExcerptPostId="3673183" WikiPostId="3673182" />
  <row Id="3" TagName="javascript" Count="1817846" ExcerptPostId="3624960" WikiPostId="3607052" />
  <row Id="4" TagName="css" Count="588062" ExcerptPostId="3644670" WikiPostId="3644669" />
  <row Id="5" TagName="php" Count="1286873" ExcerptPostId="3624936" WikiPostId="3607050" />
</tags>'

Select
P.value('@Id','BIGINT') AS ID,
P.value('@WikiPostId','BIGINT') AS WikiPostId,
P.value('@ExcerptPostId','BIGINT') AS ExcerptPostId,
P.value('@Count','BIGINT') AS Count,
P.value('@TagName','VARCHAR(100)') AS TagName
From @xml.nodes('/tags/row') PropertyFeed(P)
