我的要求是,如果用戶單擊更新數據而不更改表單上的任何字段,我希望顯示爲沒有更改,如果有任何更改,我想更新數據任何人都可以告訴我的例程出了什麼問題
我寫了一個例行程序如下更新數據
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
我得到了一段時間我需要的信息,但一段時間後它顯示的更新消息
這是我在更新
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);
}
更新代碼
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;
}
我沒有得到任何錯誤,但我想按我說
任何一個可以告訴要做的代碼是什麼我必須在此做出的更改
你可以給錯誤的詳細信息?你能否至少顯示'FaxDetailUpdate()'的代碼? – kelloti
@Kelloti: - 我沒有收到任何錯誤,但我想按照我的要求完成,因爲我說 – Dotnet
