    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string query = "SELECT TOP 1[EMP_ID]FROM EMPLOYEES WHERE[Attendance] = 'Present'ORDER BY NEWID()";

        using (SqlConnection con = new SqlConnection(constr))
        {
            using (SqlCommand cmd = new SqlCommand(query))
            {
                using (SqlDataAdapter sda = new SqlDataAdapter())
                {
                    cmd.Connection = con;
                    sda.SelectCommand = cmd;
                    using (DataTable dt = new DataTable())
                    {
                        sda.Fill(dt);
                        if (dt.Rows.Count > 0)
                        {
                            Label1.Text = dt.Rows[0]["EMP_ID"].ToString();
                        }
                        else
                        {
                            Label1.Text += "Cannot draw! ";
                        }
                    }
                }
            }
        }
    }
