In simple terms "It provides flexibility to insert data using raw SQL queries via EDM framework".

Step 1: Create a new web application

Step 2: Set up a new EDM framework with reverse engineering to the project

Step 3: The complete code of WebForm1.aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="InsertDataSQLQueryEntityApp.WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
    <form id="form1" runat="server">
      <div>
            <center>
                <table>
                    <tr>
                        <td>
                            <asp:Label ID="Label1" runat="server" Text="Insert Data with Raw SQL Query via EDM Framework" Font-Bold="true"></asp:Label></td>
                    </tr>
                </table>
                <br />
                <br />
                <table>
                    <tr>
                        <td>

                        <td>
                            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td>
                            <asp:Label ID="Label3" runat="server" Text="Please Enter LastName: " ForeColor="Brown" Font-Bold="true" Font-Italic="true"></asp:Label></td>
                        <td>
                            <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td>
                            <asp:Label ID="Label4" runat="server" Text="Please Enter Age: " ForeColor="Brown" Font-Bold="true" Font-Italic="true"></asp:Label></td>
                        <td>
                            <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td colspan="2" align="center">
                            <asp:Button ID="Button1" runat="server" Text="Insert Data" OnClick="Button1_Click" BackColor="Orange" Font-Bold="true" /><br />
                            <br />
                        </td>
                    </tr>
                </table>

                <br />
                <table>
                    <tr>
                        <td colspan="3">
                            <asp:Label ID="Label5" runat="server" Font-Bold="true"></asp:Label></td>
                    </tr>
                </table>
            </center>
        </div>
    </form>
</body>
</html>

Step 4: The complete code of WebForm1.aspx.cs looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using InsertDataSQLQueryEntityApp.Models;
namespace InsertDataSQLQueryEntityApp
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text) ||
                string.IsNullOrEmpty(TextBox3.Text))
            {
                Label5.Text = "Please Enter Some Values";
                Label5.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                objContext.Database.ExecuteSqlCommand("insert into dbo.tblEmployee(FirstName, LastName, Age)
                VALUES ('" + TextBox1.Text + "', '" + TextBox2.Text + "', " + int.Parse(TextBox3.Text) + ")");
                Label5.Text = "Data Successfully Inserted";
                Label5.ForeColor = System.Drawing.Color.Green;
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;
                TextBox3.Text = string.Empty;
            }
        }
        #region Instance MembersCompanyContext objContext = new CompanyContext();
        #endregion
    }
}

Step 5: The output of the application looks like this:

Step 6: The inserted data output of the application looks like this:
