How can I call stored procedure returning 2 tables in a controller in mvc entity framework 4?

Question

I have a stored procedure which returns 2 tables. How can I call this stored procedure from a controller in MVC. (I'm using Entity Framework 4)

---

Stored procedure:

create proc [dbo].[sp_list33](@emp dbo.list READONLY )
as
select * from dbo.Items
select * from dbo.dept

---

Here 'list' is a userdefined table type for passing table valued parameter.

CREATE TYPE [dbo].[list] AS TABLE(
    [eid] [int] NULL,
    [name] [nvarchar](50) NULL,
    [age] [int] NULL
)

In controller:

[HttpPost]
        public JsonResult Onclick(int id)
        {

            using (examemployeeEntities1 eee = new examemployeeEntities1())
            {
                //Create table value parameter
                DataTable dt = new DataTable();
                DataRow dr = dt.NewRow();
                dt.Columns.Add("eid");
                dt.Columns.Add("name");
                dt.Columns.Add("age");
                dt.Rows.Add(1, "john", 21);
                dt.Rows.Add(2, "albert", 22);
                dt.Rows.Add(3, "martin", 33);

                SqlParameter emp1 = new SqlParameter("@emp", SqlDbType.Structured);
                emp1.Value = dt;
                emp1.TypeName = "list";

                //eee.Database.ExecuteSqlCommand("EXEC sp_list4 @emp",emp1);
                var resp = eee.Database.SqlQuery<Item>("exec sp_list33 @emp", emp1);

                return Json(resp.ToList());  
            }
         }

In view: paragraph id is "sdf" and button id is "asd"!!!!!

Script:

 $("#asd").click(function () {

        var a = 1;
        var content = "<table><th>Id</th><th>Name </th><th>Age</th></tr>";
        $.ajax({
            type: 'POST',
            url: '/Home/Onclick/',
            data: { 'id': a },
            datatype: 'json',
            success: function (data) {
                $.each(data, function (i, item) {
                    content += "<tr>";
                    content += "<td style=\"background-color:White\">" + data[i].eid + "</td>";
                    content += "<td style=\"background-color:White\">" + data[i].name + "</td>";
                    content += "<td style=\"background-color:White\">" + data[i].age + "</td>";
                    content += "</tr>";
                });
                content += "</table>";
                $('#sdf').html(content);
                alert("success");
            },
            error: function () {
            }
        });

    });

Result displays content in the Item table only. How to get two entities from stored procedure? It is only retrieving the first select statement. Can any one help me to solve this..?

Since you are not using EF5, you can't go the easy way

As Microsoft stated in that link:

"Prior to EF5, Entity Framework would allow the stored procedure to be called but would only return the first result set to the calling code."

But there is always a work-around. Follow this steps and you will be able to achieve it. Although is not a very straight forward solution.

Hope this helps
