It really depends which version.  With SQL Server 2000 all you have is OPENXML().  With SQL Server 2005 there are Xml methods you can use to retrieve the data.

Unfortunately without knowing what verions you are using and what you intend to do exactly with the Xml it is difficult to help any further.

Will be using SQL 2005 to retrieve the data.

Ok.  Can you now post what you intend to do with the data?  Structure of the tables, etc.

What I want to grab the values of these columns (RiskName ,TradeType , Value , PortfolioBPS,PortfolioMTM ,ModifiedDuration )
Tried below, but I don't know how to transverse the XML tree

DROP TABLE #WorkingTable
CREATE TABLE #WorkingTable
(Data XML)


INSERT INTO #WorkingTable
SELECT * FROM OPENROWSET (BULK 'C:\Temp\Output_Files\report_output.xml', SINGLE_BLOB) AS data

select * from #WorkingTable
-- to read the XML from the working table:
DECLARE @XML AS XML, @hDoc AS INT
SELECT @XML = Data FROM #WorkingTable

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML
SELECT *
FROM OPENXML(@hDoc, '/report_output/xml/data/row', 2)
WITH (
RiskName varchar(200) '../@RiskName',
TradeType varchar(200) '../@TradeType',
Value decimal(38,4) '../@Value',
PortfolioBPS decimal(16,8) '../@PortfolioBPS',
PortfolioMTM decimal(16,8) '../@PortfolioMTM',
ModifiedDuration decimal(16,8) '../@ModifiedDuration')

EXEC sp_xml_removedocument @hDoc

First of all Xml documents do not typically use apostrophes (single quotes) for the values, but rather quotation marks (double quotes).

But to answer your question you failed to include the Xml namespace and the XPaths are incorrect.

I am trying to post the solution, but it is getting rejected.  May have to abreviate it.

I had to remove the rest of the code as EE was rejecting it.  But you should get the idea.
