Sorting By UserID

I'm trying to sort by domain user id, I can pull the user id fine but now I want to sort my SELECT by that name. How do I put the value of getUserIdentity into my SELECT statment.

Thanks

<script language="C#" runat="server">
    protected string getUserIdentity()
    {
        return HttpContext.Current.User.Identity.Name.ToString().Replace("DOMAIN\", "");
    }

    protected void Page_Load(Object sender, EventArgs e)
    {
        username = getUserIdentity();
       
        SqlConnection myConnection = new SqlConnection("Data Source=CLIENTELE;Initial Catalog=forms;Integrated Security=True");
        SqlDataAdapter myCommand = new SqlDataAdapter("SELECT * FROM formTable WHERE userID = @username ORDER BY status DESC", myConnection);

        DataSet ds = new DataSet();
        myCommand.Fill(ds, "names");

        MyDataGrid.DataSource=ds.Tables["names"].DefaultView;
        MyDataGrid.DataBind();
    }

</script>
