SqlDataAdapter is a part of the ADO.NET Data Provider. The InsertCommand, the UpdateCommand, and the DeleteCommand properties of the SqlDataAdapter object update the database with the data modifications, that are run on a DataSet object.
The following code samples that demonstrate how to use the SqlDataAdapter object to update a SQL Server database using UpdateCommand properties in SqlDataAdapter.
Imports System.Data.SqlClient
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim connetionString As String
Dim connection As SqlConnection
Dim adapter As New SqlDataAdapter
Dim sql As String
connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
connection = New SqlConnection(connetionString)
sql = "delete product where Product_name ='Product7'"
Try
connection.Open()
adapter.DeleteCommand = connection.CreateCommand
adapter.DeleteCommand.CommandText = sql
adapter.DeleteCommand.ExecuteNonQuery()
MsgBox("Row(s) deleted !! ")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
End Class
