In this article I will explain with an example, how to update data into
MySQL database with
Stored Procedure in ASP.Net using C# and VB.Net.
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
This
Stored Procedure accepts
CustomerId,
Name and
Country parameters, which are used to UPDATE the records in
Customers Table.
DELIMITER //
CREATE PROCEDURE Customers_UpdateCustomer(
IN CustomerId INT,
IN Name VARCHAR(100) ,
IN Country VARCHAR(50)
)
BEGIN
UPDATE Customers
SET Name = Name,
Country = Country
WHERE Customers.CustomerId = CustomerId;
END//
DELIMITER ;
HTML Markup
The HTML Markup consists of following controls:
TextBox – For capturing the values of CustomerId, Name and Country.
Button – For updating record.
The Button has been assigned with an OnClick event handler.
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td style="width: 60px">Id<br />
<asp:TextBox ID="txtId" runat="server" Width="50px" />
</td>
<td style="width: 150px">Name<br />
<asp:TextBox ID="txtName" runat="server" Width="140px" />
</td>
<td style="width: 150px">Country:<br />
<asp:TextBox ID="txtCountry" runat="server" Width="140px" />
</td>
<td style="width: 200px">
<br />
<asp:Button Text="Update" runat="server" OnClick="OnUpdate" />
</td>
</tr>
</table>
Namespaces
You will need to import the following namespaces.
C#
using System.Data;
using System.Configuration;
using MySql.Data.MySqlClient;
VB.Net
Imports System.Data
Imports System.Configuration
Imports MySql.Data.MySqlClient
Updating with Stored Procedure into MySQL Database in ASP.Net
When Update Button is clicked, first the connection is read from Web.Config file.
The CustomerId, Name and Country fields are fetched from their respective TextBoxes.
C#
protected void OnUpdate(object sender, EventArgs e)
{
string spName = "Customers_UpdateCustomer";
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
using (MySqlCommand cmd = new MySqlCommand(spName, con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@CustomerId", txtId.Text);
cmd.Parameters.AddWithValue("@Name", txtName.Text);
cmd.Parameters.AddWithValue("@Country", txtCountry.Text);
con.Open();
int i = cmd.ExecuteNonQuery();
con.Close();
if (i > 0)
{
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Customer record updated.');", true);
}
else
{
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Customer not found.');", true);
}
}
}
}
VB.Net
Protected Sub OnUpdate(ByVal sender As Object, ByVal e As EventArgs)
Dim spName As String = "Customers_UpdateCustomer"
Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
Using con As MySqlConnection = New MySqlConnection(constr)
Using cmd As MySqlCommand = New MySqlCommand(spName, con)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.AddWithValue("@CustomerId", txtId.Text)
cmd.Parameters.AddWithValue("@Name", txtName.Text)
cmd.Parameters.AddWithValue("@Country", txtCountry.Text)
con.Open()
Dim i As Integer = cmd.ExecuteNonQuery()
con.Close()
If i > 0 Then
ClientScript.RegisterStartupScript(Me.GetType(), "alert", "alert('Customer record updated.');", True)
Else
ClientScript.RegisterStartupScript(Me.GetType(), "alert", "alert('Customer not found.');", True)
End If
End Using
End Using
End Sub
