GridView กับฐานข้อมูล Oracle เชื่อมต่อได้วิธีไหนบ้างครับ

    Sub Page_Load(sender As Object, e As EventArgs)
		Dim strConnString As String
		strConnString = "Data Source=TCDB;User Id=myuser;Password=mypassword;"
		objConn = New OracleConnection(strConnString)
		objConn.Open()

        BindData()
    End Sub

   Sub BindData()
	   Dim strSQL As String
	   strSQL = "SELECT * FROM customer"

	   Dim dtReader As OracleDataReader
	   objCmd = New OracleCommand(strSQL, objConn)
	   dtReader = objCmd.ExecuteReader()

	   '*** BindData to GridView ***'
	   myGridView.DataSource = dtReader
	   myGridView.DataBind()

	   dtReader.Close()
	   dtReader = Nothing

   End Sub

   Sub Page_UnLoad()
	   objConn.Close()
	   objConn = Nothing
   End Sub
