Hi,
I have a table called StaffAppointment that I want to display in a view MVC4 that looks like the table below.

HTML

Staff no	date booked	Time From	time to
1	        2013-07-01	      3          4
1	        2013-07-09	      2	         3
1	        2013-07-18	      5	         7

But when I query the DB:

C#

var model = from x in dba. StaffAppointments where x.StaffNo == 1 select x;
return View(model.ToList());

It's displaying a duplicate of the first row like the table below.
On View

XML

@model IEnumerable<MyApp.Models.StaffAppointment>

XML

Staff no    date booked Time From   time to
1           2013-07-01        3          4
1           2013-07-01        3          4
1           2013-07-01        3          4

Please help solve this problem.
This is my Model class

C#

public class StaffAppointment
    {
        public Int32 Staffno { get; set; }
        public DateTime DateBooked { get; set; }
        public Nullable<int> TimeTo { get; set; }
        public Nullable<int> TimeFrom { get; set; }
    }

This is my View:

HTML

@model IEnumerable<MyApp.Models.StaffAppointment>

@{
    ViewBag.Title = "AddAppointment";
}


<table>
    <tr>
        <th>
           Staff no
        </th>
        <th>
           DateBooked
        </th>
        <th>
            TimeFrom
        </th>
        <th>
           TimeTo
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item. Staffno)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.DateBooked)
        </td>
       
        <td>
            @Html.DisplayFor(modelItem => item.TimeFrom)
        </td>
         <td>
            @Html.DisplayFor(modelItem => item.TimeTo)
        </td>
        
    </tr>
}

</table>

I think its problem of your query, which retrieve value corresponding just

C#

var model = from x in dba. StaffAppointments where x.StaffNo == 1 select ALL;
return View(model.ToList());

Hi,

After seeing this, i've identified that you didn't have any primary key. Most often, ORM creates problem (its called problem of identity mapping, which we can discuss later). For now try to rewrite your query like:

SQL

var model = from x in dba. StaffAppointments 
where x.StaffNo == 1 
select x.Staffno, x.DateBooked, x.TimeFrom, x.TimeTo;

return View(model.ToList());

It should resolve problem...
