How to get data from database between two dates when Fromdate and Todate are same date. i.e (2/2/2012 and 2/2/2012).

select std.reg_no,std.stud_name,bat.batch_name,convert(varchar,col.amt_received_date,103) as amt_received,
col.receipt_no,col.fee_amt,adm.username
 from tbl_collections col join tbl_admin adm
on adm.id=col.id join tbl_student std on col.sid=std.sid join
tbl_batches bat on std.bid=bat.bid where adm.username=@username AND amt_received_date between @fromdate and @todate

protected void onselect_change(object sender, EventArgs e)
{
    try
    {
        string fdate = txtCalendar.Text.ToString();
        string tdate = txtCalendar1.Text.ToString();
        DateTime fromd = DateTime.Parse(fdate, System.Globalization.CultureInfo.InvariantCulture);
        DateTime tod = DateTime.Parse(tdate, System.Globalization.CultureInfo.InvariantCulture);
        string user = cashier_list.SelectedItem.Text;
        DataSet ds2 = new DataSet();
        ds2 = obj.fee_collectionsreport(3, 0, user, fromd, tod);
        collection_grid.DataSource = ds2;
        collection_grid.DataBind();
    }
    catch { }
}
