SQL Server 2014: Extracting data from XML using OpenXML and BulkColumn - sql-server

Question

I am trying to extract data from a big xml file using OpenXML and BulkColumn and then save it into a new table called badges.
I am also executing a select statement to show the content of the table.
The file is stored locally. The file uses the attribute-centric mapping and has tens of thousands of rows.
The code I am using is:
CREATE TABLE dbo.badges (
Id int,
Name NVARCHAR(1000),
Date date,
Class smallint,
TagBased nvarchar(10),
);
DECLARE #XMLDoc XML;
DECLARE #XMLDocID INT;
SELECT #XMLDoc = BulkColumn
FROM OPENROWSET(BULK 'C:\Users\Zuhair\Desktop\Badges.xml', SINGLE_BLOB);
EXEC sys.sp_xml_preparedocument #XMLDocID OUTPUT, #XMLDoc;
SELECT Id, Name, Date, Class, TagBased
FROM OPENXML(#XMLDocID, '/badges/row')
WITH (Id int 'Id',
Name NVARCHAR(1000) 'Name',
Date date 'Date',
Class smallint 'Class',
TagBased nvarchar(10) 'TagBased');
INSERT INTO dbo.badges (Id, Name, Date, Class, TagBased)
SELECT *
FROM OPENXML(#XMLDocID, '/badges/row')
WITH (Id int 'Id',
Name NVARCHAR(1000) 'Name',
Date date 'Date',
Class smallint 'Class',
TagBased nvarchar(10) 'TagBased');
exec sp_xml_removedocument #XMLDocID;
However, when I execute the above code I get the following result:
Here is a sample of the XML data that I am using:
<badges>
<row Id="1" UserId="2" Name="Autobiographer" Date="2010-08-11T18:25:03.937" Class="3" TagBased="False" />
<row Id="2" UserId="3" Name="Autobiographer" Date="2010-08-11T18:25:03.997" Class="3" TagBased="False" />
<row Id="3" UserId="4" Name="Autobiographer" Date="2010-08-11T18:25:04.107" Class="3" TagBased="False" />
<row Id="4" UserId="22" Name="Autobiographer" Date="2010-08-11T19:35:05.283" Class="3" TagBased="False" />
<row Id="5" UserId="33" Name="Autobiographer" Date="2010-08-11T19:35:05.330" Class="3" TagBased="False" />
<row Id="6" UserId="27" Name="Autobiographer" Date="2010-08-11T19:40:05.490" Class="3" TagBased="False" />
...
</badges>
Why am I getting this result rather than a table that has the desired data?

Answer 1

The usage of FROM OPENXML with the related procedures to prepare and remove a document are out-dated and should not be used any more.
Try this:
DECLARE #xml XML =
'<badges>
<row Id="1" UserId="2" Name="Autobiographer" Date="2010-08-11T18:25:03.937" Class="3" TagBased="False" />
<row Id="2" UserId="3" Name="Autobiographer" Date="2010-08-11T18:25:03.997" Class="3" TagBased="False" />
<row Id="3" UserId="4" Name="Autobiographer" Date="2010-08-11T18:25:04.107" Class="3" TagBased="False" />
<row Id="4" UserId="22" Name="Autobiographer" Date="2010-08-11T19:35:05.283" Class="3" TagBased="False" />
<row Id="5" UserId="33" Name="Autobiographer" Date="2010-08-11T19:35:05.330" Class="3" TagBased="False" />
<row Id="6" UserId="27" Name="Autobiographer" Date="2010-08-11T19:40:05.490" Class="3" TagBased="False" />
</badges>';
SELECT r.value('#Id','int') AS Id
,r.value('#UserId','int') AS UserId
,r.value('#Name','varchar(max)') AS Name
,r.value('#Date','datetime') AS [Date]
,r.value('#Class','int') AS Class
,r.value('#TagBased','bit') AS TagBased
FROM #xml.nodes('/badges/row') AS A(r)
UPDATE The full (minimal) code
DECLARE #XMLDoc XML;
SELECT #XMLDoc = BulkColumn
FROM OPENROWSET(BULK 'C:\Users\Zuhair\Desktop\Badges.xml', SINGLE_BLOB) AS x;
SELECT r.value('#Id','int') AS Id
,r.value('#UserId','int') AS UserId
,r.value('#Name','varchar(max)') AS Name
,r.value('#Date','datetime') AS [Date]
,r.value('#Class','int') AS Class
,r.value('#TagBased','bit') AS TagBased
FROM #XMLDoc.nodes('/badges/row') AS A(r)

Answer 2

First and foremost, I like Shnugo's answer and I believe that is the path you should follow.
For your specific question, the reason you got all the NULL is because you are extracting data from the ATTRIBUTE and you forgot all the #.
Try the code below:
DECLARE #XMLDoc XML =
'<badges>
<row Id="1" UserId="2" Name="Autobiographer" Date="2010-08-11T18:25:03.937" Class="3" TagBased="False" />
<row Id="2" UserId="3" Name="Autobiographer" Date="2010-08-11T18:25:03.997" Class="3" TagBased="False" />
<row Id="3" UserId="4" Name="Autobiographer" Date="2010-08-11T18:25:04.107" Class="3" TagBased="False" />
<row Id="4" UserId="22" Name="Autobiographer" Date="2010-08-11T19:35:05.283" Class="3" TagBased="False" />
<row Id="5" UserId="33" Name="Autobiographer" Date="2010-08-11T19:35:05.330" Class="3" TagBased="False" />
<row Id="6" UserId="27" Name="Autobiographer" Date="2010-08-11T19:40:05.490" Class="3" TagBased="False" />
</badges>';
DECLARE #XMLDocID INT;
EXEC sys.sp_xml_preparedocument #XMLDocID OUTPUT, #XMLDoc;
SELECT Id, Name, Date, Class, TagBased
FROM OPENXML(#XMLDocID, '/badges/row')
WITH (Id int '#Id',
Name NVARCHAR(1000) '#Name',
Date date '#Date',
Class smallint '#Class',
TagBased nvarchar(10) '#TagBased');
exec sp_xml_removedocument #XMLDocID;
