Vb.net Connectivity using ADO.NET - Deleting Record
Deleting a Record
We will use Authors table in Pubs sample database to work with this code. Drag a button onto the form and place the following code.
Imports System.Data.SqlClient
Public Class Form3 Inherits System.Windows.Forms.Form
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim ra as Integer
Private Sub Form3_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("Delete from Authors where city='Oakland'",_
myConnection)
'since no value is returned we use ExecuteNonQuery
ra=myCommand.ExecuteNonQuery()
MessageBox.Show("Records affected" & ra)
myConnection.Close()
End Sub
End Class
