Insert Stored Proc with Raw SQL Query via EDF Framework

Question: What is insert stored proc with raw SQL query via EDM framework?

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:

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 InsertSPSQLQueryEntityApp.Models;

namespace InsertSPSQLQueryEntityApp

{

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("EXEC [dbo].[InsertEmpData] '" + 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:
