Question

背景我的存储过程'GetAtdRecord_Sp'可选择接受参数'EmplID'，否则默认值为null。它适用于SQl服务器管理工作室，即使我没有像我想要的那样提供任何价值。

 exec GetAtdRecord_Sp     // This works 
 exec GetAtdRecord_Sp 23 //  This works too with value.

问题： 但是当我从Asp.net MVC应用程序通过Linq执行它到Sql代码时，它需要一个参数并抛出错误：

Error   1   No overload for method 'GetAtdRecord_Sp' takes 0 arguments

如果我传递的值如下所示，则有效。

的代码： 的使用EmployeeAttendance_app.Models;

namespace EmployeeAttendance_app.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Message = "Precise Technology Consultants";
            var DataContext = new EmployeeAtdDataContext();
            //var EmployeeAtd = DataContext.GetAttendance_Sp();
            IEnumerable<GetAtdRecord_SpResult> EmployeeAtd =  DataContext.GetAtdRecord_Sp(22).ToList();
            return View(EmployeeAtd);
        }

但是当我像这样将GetAtdRecord_Sp（）留空时它不起作用。

商店程序：

    ALTER PROCEDURE [dbo].[GetAtdRecord_Sp] 
    @EmplID INT = NULL
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.

尝试刷新 .edmx 文件。更改后，代码库中的存储过程未被更改。

没有重载需要0个参数用于存储过程
