Vb.net Connectivity using ADO.NET - Updating Record

Updating Records

We will update a row in Authors table. Drag a button onto the form and place the following code.

Imports System.Data.SqlClient
Public Class Form4 Inherits System.Windows.Forms.Form
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim ra as Integer
Private Sub Form4_Load(ByVal sender As System.Object, ByVal e_
As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e_
As System.EventArgs) Handles Button1.Click
myConnection = New SqlConnection("server=localhost;uid=sa;pwd=;database=pubs")
'you need to provide password for sql server
myConnection.Open()
myCommand = New SqlCommand("Update Authors Set city='Oakland' where city=_
'San Jose' ",myConnection)
ra=myCommand.ExecuteNonQuery()
MessageBox.Show("Records affected" & ra)
myConnection.Close()
End Sub
