This class is created whenever the MySql Data Provider encounters an error generated from the server. Any open connections are not automatically closed when an exception is thrown. If the client application determines that the exception is fatal, it should close any open objects or objects. The following example generates a MySqlException due to a missing server, and then displays the exception.


        Public Sub ShowException()
        Dim mySelectQuery As String = "SELECT column1 FROM table1"
        Dim myConnection As New MySqlConnection ("Data Source=localhost;Database=Sample;")
        Dim myCommand As New MySqlCommand(mySelectQuery, myConnection)

        Try
        myCommand.Connection.Open()
        Catch e As MySqlException
        MessageBox.Show( e.Message )
        End Try
        End Sub


        public void ShowException()
        {
        string mySelectQuery = "SELECT column1 FROM table1";
        MySqlConnection myConnection =
        new MySqlConnection("Data Source=localhost;Database=Sample;");
        MySqlCommand myCommand = new MySqlCommand(mySelectQuery,myConnection);

        try
        {
        myCommand.Connection.Open();
        }
        catch (MySqlException e)
        {
        MessageBox.Show( e.Message );
        }
        }
