Must have missed something:


I have this test routine :

       public static void Test_EXP_0071TAttached()
        {
            using (var context = new PluczExp_PluczContext(Config.model.SqlServer))
            {
                var sql = "dbo.Exp_0071TAttached";
                var attached = context.Database.SqlQuery<string>(sql).ToString();
                Console.WriteLine($"EXP_0071TAttached returns {attached}");
            }
        }

... that returns :" EXP_0071TAttached returns dbo.Exp_0071TAttached."

Here's the scalar returning function :

USE [Exp_Plucz]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[Exp_0071TAttached]()
RETURNS int
AS
begin
	declare @result bit = 0
	select @result = CAST(
		CASE WHEN DB_Id('EXP_0071T') is not null THEN 1
		ELSE 0
		END
	AS BIT)
	RETURN @RESULT 
END
