Question

Entity Framework for a stored procedure that returns results of an XPath query on XML data.

Asked by: MDKIMZEY

I have a stored procedure that returns XML column elements and attributes for a user-specified row in a SQL Table as a row.

Since this sql stored procedure returns a single row containing data from a XML column - (and the columns of this row are not defined by an existing SQL Table or view) - what return type should be specified for the EDMX Function Import?

ALTER PROCEDURE [dbo].[GetXmlData]
	@GuidOfInterest uniqueidentifier
 
declare @XmlCol as xml;							
select @XmlCol = XmlTableCol from dbo.TableWithXmlCol
	    where UniqueGuid = @GuidOfInterest
	
select @XmlCol.value('(//Root/@RootName)[1]', 'char(38)' ) as RootName,
          @XmlCol.value('(//Root/@RootGUID)[1]', 'char(38)' ) as RootGuid,
          @XmlCol.value('(//Root/SetupName)[1]', 'char(80)') as SetupName

There probably is a way to call a stored procedure that returns the result of an XPath query on XML data in a SQL table using Entity Framework - but I have not found it.

For this case, as well as stored procedures that use the PIVOT command, I had to use straight ADO.net.  ADO.net calls were successful.
