After giving default value to NULL, store procedure still demand the variable.

Hello Everyone,

Below is my Store-procedure.

ALTER PROC usp_module_assigned_details
(
 @CounrtyID BIGINT = NULL,
 @ModuleID BIGINT = NULL,
 @case INT 
)

AS BEGIN

IF @case = 1 -- Select assigned module to the country
            BEGIN
			SELECT ModuleID
			FROM Country_Module_Assign
			WHERE CountryID=@CounrtyID
			END

END

I use this type style of store-procedure with ado.net and it works fine, without any issue. [I use more than 50 store procedure in my previous project. All of them work perfectly].

But when I try to use store-procedure with entity framework, it doesn't tale my variable (@ModuleID BIGINT = NULL), AS NULL. I already defined ion in my declaration part.

When I execute it by giving @CountryID and @case

exec usp_module_assigned_details 221,1

It says Procedure or function 'usp_module_assigned_details' expects parameter '@case', which was not supplied.

But when I execute like below

exec usp_module_assigned_details 221 ,NULL,1

It executes perfectly.

My question is that when I already defines @ModuleID BIGINT  AS NULL, whey it is demanding it.

Below is my EF Code.

int country_id = Convert.ToInt32(Session["USER-Country"].ToString());
            SqlParameter param1 = new SqlParameter("@CounrtyID", Convert.ToInt32(country_id));
            SqlParameter param2 = new SqlParameter("@case", 1);
            var ModuleList = db.Database.SqlQuery<ModuleModel>("usp_module_assigned_details  @CounrtyID,@case", param1, param2).ToList();
            ViewBag.AssignedModules = ModuleList;
            return ModuleList;

Please Suggest.
