Question

ASP.NET MVC, VB.NET, SQL Server 2008 R2, Entity Framework v4

I created a stored procedure that returns an integer value

PROCEDURE [dbo].[spProfileCount] 
@STARTLETTER char(1) = 'A'
AS
BEGIN  
    SET NOCOUNT ON

    SELECT count(*) 
    FROM [Profils]
    WHERE LEFT(lastname,1) =  @STARTLETTER 

END

I imported the stored proc in EF and created a function. In that function I defined Returns a collection of as scalar of type Int32 (which is consistent with what I see when I press the [get column information] button).

So how does this work in the controller? I’ve tried many things without success.

I.e.

Dim n As Integer = 0 
n = context.spProfileCount("Q")

Error:

Value of type System.data.Objects.ObjectResults(of integer?)’ can not
be converted to ‘integer’.

Answer 1

Have you tried what is shown in the documentation?

ObjectResult(Of T) Class.

// Execute the query and get the ObjectResult.
ObjectResult<Product> queryResult = query.Execute(MergeOption.AppendOnly);

// Iterate through the collection of Product items.
foreach (Product result in queryResult)
    Console.WriteLine("{0}", result.Name);

If you are sure you’re going to have only one row, it’s going to be just queryResult.Single()
