Dataadapter DeleteCommand - OLEDB Data Source

OleDbDataAdapter is a part of the ADO.NET Data Provider. The OleDbDataAdapter works with the DataSet to provide a disconnected data retrieval mechanism. The InsertCommand, UpdateCommand, and DeleteCommand properties of the OleDbDataAdapter are Command objects that manage updates to the specified data source according to modifications.

The following Source Code shows how to perform delete data from a database using DeleteCommand property of OleDbDataAdapter.




Imports System.Data.OleDb
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 OleDbConnection
        Dim oledbAdapter As New OleDbDataAdapter
        Dim sql As String
        connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
        connection = New OleDbConnection(connetionString)
        sql = "delete from Users where UserID = 'user1'"
        Try
            connection.Open()
            oledbAdapter.DeleteCommand = connection.CreateCommand
            oledbAdapter.DeleteCommand.CommandText = sql
            oledbAdapter.DeleteCommand.ExecuteNonQuery()
            MsgBox("Row(s) Deleted !! ")
