I am trying to create a function import for a stored procedure.  

When I try to add the function import and click "Get Column information"  i get the response the stored procedure returns no columns.   It does not allow me to pass in any default values.

Sorry I should have mentioned I am working with entity framework.

I have a stored procedure re (That I cannot modify)  which returns a query.  This query will not map to a specific entity so I need to create a complex type.  

In order to do this within visual studio I create a funciton import select complex type then click Get Colum information.  The problem is that because you cannot assign any values for running the stored procedure the design gives the error  "stored procedure returns no columns".

Hi VolunteerDevelopmentAgency;

To your statement, "The problem is that because you cannot assign any values for running the stored procedure the design gives the error  "stored procedure returns no columns".", For some reason the EF designer believes that the stored procedure is not returning any columns. Can you please post the Stored Procedure.

Thanks;
Fernando

Unfortunately since you cannot modify the Stored Procedure, there is nothing you can do about it.

If you could modify the Stored Procedure you would make sure that SET NOCOUNT ON was the first executable code.  This would allow your application to see the result sets.

Hi VolunteerDevelopmentAgency;

First I am NOT a SQL Server Guru but looking at your SP it looks like to me that you are returning multiple result sets which are NOT supported in EF.

If you want to try a work around you can look at this article,  ADO.NET Entity framework advanced scenarios: Working with stored procedures that return multiple resultsets as well as downloading the ADO.NET Entity Framework Extensions.

You make a good point, there is one case when more than one resultset is returned (abbreviated below for clarity). So if EF has a problem with multiple resultsets, then that is going to be a problem.

ELSE IF LOWER(@ReportType) = 'details'
BEGIN
	IF @AllContacts = 0
	BEGIN
		SELECT *
		FROM OrganisationResults
		WHERE RowNumber 
			BETWEEN (@SelectPage - 1) * @PageSize + 1 
			AND @SelectPage * @PageSize
		ORDER BY
			[OrganisationName],
			[SiteName]
				
		-- Also return a count of the total number of pages
		SELECT CEILING(COUNT(*)/CAST(@PageSize AS float)) AS TotalPages
		FROM
			#MatchingOrganisations MO
			INNER JOIN tblOrganisations ORG ON MO.OrganisationID = ORG.OrganisationID
			INNER JOIN tblSites SIT ON ORG.OrganisationID = SIT.FKOrganisationID
		WHERE
			SIT.Deleted = 0
	END
	ELSE
	BEGIN
		-- Return the results 
		SELECT *
		FROM OrganisationResults
		WHERE RowNumber 
			BETWEEN (@SelectPage - 1) * @PageSize + 1 
			AND @SelectPage * @PageSize
		ORDER BY
			[OrganisationName],
			[SiteName],
			[Surname],
			[FirstName]
				
		-- Also return a count of the total number of pages
		SELECT CEILING(COUNT(*)/CAST(@PageSize AS float)) AS TotalPages
		FROM
			#MatchingOrganisations MO
			INNER JOIN tblOrganisations ORG ON MO.OrganisationID = ORG.OrganisationID
			INNER JOIN tblSites SIT ON ORG.OrganisationID = SIT.FKOrganisationID
			INNER JOIN tblSiteContacts SCN ON SIT.SiteID = SCN.FKSiteID
			INNER JOIN tblContacts CON ON SCN.FKContactID = CON.ContactID
		WHERE
			SIT.Deleted = 0 AND
			CON.Deleted = 0 AND
			CON.AcceptsEmails = 1
	END
END
