第二个存储过程中的asp.net实体框架存储过程错误

Question

In ASP.NET MVC I have this controller:

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using test.DB;
using test.EFView;

namespace test.Controllers
{
    public class OrderAndDDTController : Controller
    {

        // GET: OrderAndDDT
        public ActionResult Index(DateTime? Start, DateTime? End)
        {
            if (Start != null && End != null)
            {
                using (var db = new PROVA_ETLEntities())
                {
                    ViewBag.Start = Start;
                    ViewBag.End = End;
                    var list = db.ddsp_getFamQty_FI(Start, End).OrderBy(x => x.Famiglia).ToList();
                    return View(list);
                }
            }

            return View();
        }

        public ActionResult Customer(DateTime? Start, DateTime? End, string Famiglia)
        {
            if (Start != null && End != null)
            {
                using (var db = new PROVA_ETLEntities())
                {
                    ViewBag.Start = Start;
                    ViewBag.End = End;
                    ViewBag.Famiglia = Famiglia;
                    var list = db.ddsp_getFamCustQty_FI(Start, End, Famiglia).OrderBy(x => x.Cliente).ToList();
                    return View(list);
                }
            }

            return View();
        }
    }
}

In the Index view I have a button that run the second actionresult , "Customer". When I try to run it, it goes in timeout. I try the same stored procedure with the parameters that the code above will pass, and it takes less then one second to execute. It seems that the first SQL statement remain opening and will not allow to send the second (I see it in SQL Activity Monitor).

The point that goes in error it's the autogenerate code (By Entity Framework) and is this

public virtual ObjectResult<ddsp_getFamCustQty_Result> ddsp_getFamCustQty_FI(Nullable<System.DateTime> dateStart, Nullable<System.DateTime> dateEnd, string family)
{
    var dateStartParameter = dateStart.HasValue ?
        new ObjectParameter("dateStart", dateStart) :
        new ObjectParameter("dateStart", typeof(System.DateTime));

    var dateEndParameter = dateEnd.HasValue ?
        new ObjectParameter("dateEnd", dateEnd) :
        new ObjectParameter("dateEnd", typeof(System.DateTime));

    var familyParameter = family != null ?
        new ObjectParameter("family", family) :
        new ObjectParameter("family", typeof(string));

    return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<ddsp_getFamCustQty_Result>("ddsp_getFamCustQty_FI", dateStartParameter, dateEndParameter, familyParameter);
} 

on the last row, with SQL timeout exception.

Answer 1

您可以设置命令超时，如下所示

   ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 180;//in seconds
