Why is select query not working? - sql

Question

I am trying to select each PartNum, WarehouseCode, and OnhandQty from the "StkPart" attributes and select the plant from the "Plant" attribute. There is only one "Plant" in this xml file and the "Plant" would be associated with each row from the "StkPart" attribute.
For Example:
PartNum WarehouseCode OnhandQty Plant
1. 10-12345 Corona 150 MfgSys
2. 10-12351 Cork 1 MfgSys
3. 10-51617a Here 198 MfgSys
4. 10-97654 There 67 MfgSys
This is what I have been trying (The XML code is at the bottom):
This code works and enters the data into my table:
USE Database
GO
CREATE TABLE XMLwithOpenXML
(
Id INT IDENTITY PRIMARY KEY,
XMLData XML,
LoadedDateTime DATETIME
)
INSERT INTO XMLwithOpenXML(XMLData, LoadedDateTime)
SELECT CONVERT(XML, BulkColumn) AS BulkColumn, GETDATE()
FROM OPENROWSET(BULK 'C:\Test\StockStatusReport30597.XML', SINGLE_BLOB) AS x;
SELECT * FROM XMLwithOpenXML
Then I try to select the data, but this is not working:
USE Database
GO
DECLARE #XML AS XML, #hDoc AS INT, #SQL NVARCHAR (MAX)
SELECT #XML = XMLData FROM XMLwithOpenXML
EXEC sp_xml_preparedocument #hDoc OUTPUT, #XML
SELECT PartNum
FROM OPENXML(#hDoc, 'ReportDataSet/PartNum')
WITH
(
PartNum [varchar](50) '#PartNum'
)
EXEC sp_xml_removedocument #hDoc
GO
How do I get the above code to work?
Here is the XML file to download:

This might help
Declare #xml xml = N'<ReportDataSet
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
...
</ReportDataSet>'
Select
N.value('PartNum[1]', 'varchar(20)') PartNum,
N.value('WarehouseCode[1]', 'varchar(20)') WarhouseCode,
N.value('OnhandQty[1]', 'int') OnhandQty,
#xml.value('(/ReportDataSet/Plant/Plant)[1]', 'varchar(20)') Plant
from
#xml.nodes('/ReportDataSet/StkPart') as T(n)
I've cut some stuff out of the example below to fit into the limitations of SQLFiddle, but it worked with the query from the question with appropriate namespaces added:
Example SQLFiddle
For your big data example, you'll need to set the default namespace for the query:
With xmlnamespaces (default 'http://www.epicor.com/Mfg/100')
Select
N.value('PartNum[1]', 'varchar(20)') PartNum,
N.value('WarehouseCode[1]', 'varchar(20)') WarhouseCode,
N.value('OnhandQty[1]', 'decimal(10,2)') OnhandQty,
#xml.value('(/ReportDataSet/Plant/Plant)[1]', 'varchar(20)') Plant
from
#xml.nodes('/ReportDataSet/StkPart') as T(n)
