Can any one tell what's going wrong with my Routine - asp.net

Question

My requirement is if the user click on update data with out changing any field on the form i would like to show as No changes made and if any changes i would like to update the data
I have written a Routine for updating data as follows
CREATE DEFINER=`root`#`%` PROCEDURE `uspEmployeeFaxDetailsUpdate`(_EmpID int(11),
_FaxNumberTypeID varchar(45),
_FaxNumber decimal(10,0),
_EndDate datetime)
BEGIN
declare p_ecount int;
set p_ecount= (select count(1) from tblemployeefaxdetails where
FaxNumberTypeID=_FaxNumberTypeID and
FaxNumber=_FaxNumber and
EndDate='9999-12-31');
if p_ecount=0 then
begin
update tblemployeefaxdetails
set
EndDate=_EndDate WHERE EmpID=_EmpID and EndDate="9999-12-31";
insert into tblemployeefaxdetails(EmpID,FaxNumberTypeID,FaxNumber,StartDate,EndDate) values
(_EmpID,_FaxNumberTypeID,_FaxNumber,curdate(),'9999-12-31');
end;
end if;
END
I am getting some time my required message but some time it is showing the update message
This is my code on update
oEmployeePersonalData.EmpID = EmpID;
oEmployeePersonalData.FaxNumberTypeID = ddlFaxTypeID.SelectedItem.Text;
oEmployeePersonalData.FaxNumber = Convert.ToInt64(txtFaxNumber.Text);
oEmployeePersonalData.EndDate = DateTime.Today.AddDays(-1);
if (oEmployeePersonalData.FaxDetailUpdate())
{
oMsg.Message = "Updated Sucessfully";
Label m_locallblMessage;
oMsg.AlertMessageBox(out m_locallblMessage);
Page.Controls.Add(m_locallblMessage);
}
else
{
oMsg.Message = "Not Sucessfully";
Label m_locallblMessage;
oMsg.AlertMessageBox(out m_locallblMessage);
Page.Controls.Add(m_locallblMessage);
}
Updated code
public bool FaxDetailUpdate()
{
m_bFlag = false;
try
{
m_oCmd = new MySqlCommand(StoredProcNames.tblEmployeeFaxdetails_uspEmployeeFaxdetailsUpdate, m_oConn);
m_oCmd.CommandType = CommandType.StoredProcedure;
m_oCmd.Parameters.AddWithValue("_EmpID", EmpID);
m_oCmd.Parameters.AddWithValue("_FaxNumberTypeID", FaxNumberTypeID);
m_oCmd.Parameters.AddWithValue("_FaxNumber", FaxNumber);
m_oCmd.Parameters.AddWithValue("_EndDate", EndDate);
if (m_oConn.State == ConnectionState.Closed)
{
m_oConn.Open();
}
if ((m_oCmd.ExecuteNonQuery()) > 0)
{
this.m_bFlag = true;
}
}
catch (MySqlException oSqlEx)
{
m_sbErrMsg.Length = 0;
m_sbErrMsg = Utilities.SqlErrorMessage(oSqlEx);
//DB write the Error Log
m_oErrlog.Add(m_sbErrMsg.ToString(), DateTime.Now);
}
catch (Exception oEx)
{
m_sbErrMsg = Utilities.ErrorMessage(oEx);
//DB write the Error Log
m_oErrlog.Add(m_sbErrMsg.ToString(), DateTime.Now);
}
finally
{
m_oConn.Close();
}
return this.m_bFlag;
}
I am not getting any error but i would like to be done as per i said
Can any one tell what changes i have to made in this

I do not really understand the routine, what the magic date 9999-12-31 represents, and why a new record is inserted every time, instead of updating the old one.
What you can do, is have the routine return a indicator if the row was changed or not, returning the value of p_ecount through a OUT parameter.
For more information on how to use OUT parameters using the .net MySql client see http://dev.mysql.com/doc/refman/5.0/en/connector-net-programming-stored.html
