In this article I will explain with an example, how to select data from
MySQL database using
Stored Procedure in ASP.Net MVC.
Database
I have made use of the following table Customers with the schema as follows.
I have already inserted few records in the table.
Note: You can download the database table SQL by clicking the download link below.
Stored Procedure
DELIMITER //
CREATE PROCEDURE Customers_GetCustomers()
BEGIN
SELECT CustomerId, Name,Country
FROM Customers
END//
DELIMITER ;
Model
The Model class consists of following properties.
public class CustomerModel
{
public int CustomerId { get; set; }
public string Name { get; set; }
public string Country { get; set; }
}
Namespaces
You will need to import the following namespaces.
using System.Data;
using System.Configuration;
using MySql.Data.MySqlClient;
Controller
The Controller consists of following Action method.
Action Method for handling GET operation
Inside this Action method, first the connection is read from Web.Config file.
The records are fetched from the
Customers Table of
MySQL database with
Stored Procedure using
MySqlDataReader class.
Then, WHILE loop is executed and records are copied into the Generic List collection of CustomerModel class object.
Finally, the Generic List collection of CustomerModel class object is returned to the View.
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
string spName = "Customers_GetCustomers";
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
List<CustomerModel> customers = new List<CustomerModel>();
using (MySqlConnection con = new MySqlConnection(constr))
{
using (MySqlCommand cmd = new MySqlCommand(spName, con))
{
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
using (MySqlDataReader sdr = cmd.ExecuteReader())
{
while (sdr.Read())
{
customers.Add(new CustomerModel
{
CustomerId = Convert.ToInt32(sdr["CustomerId"]),
Name = sdr["Name"].ToString(),
Country = sdr["Country"].ToString()
});
}
}
con.Close();
}
return View(customers);
}
}
}
View
HTML Markup
Inside the View, in the very first line the CustomerModel class is declared as IEnumerable which specifies that it will be available as a Collection.
For displaying the records, an HTML Table is used. A FOR EACH loop will be executed over the Model which will generate the HTML Table rows with the Customer records.
@model IEnumerable<CustomerModel>
@using Select_SP_MySQL_MVC.Models
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<table cellpadding="0" cellspacing="0">
<tr>
<th>Customer Id</th>
<th>Name</th>
<th>Country</th>
</tr>
@foreach (CustomerModel customer in Model)
{
<tr>
<td>@customer.CustomerId</td>
<td>@customer.Name</td>
<td>@customer.Country</td>
</tr>
}
</table>
</body>
</html>
