Quando ho un anno bisestile nel mio database (es .: 29 febbraio 2012). Le funzioni EntityFunctions.CreateDateTime getta System.Data.SqlClient.SqlException: Conversion failed when converting date and/or time from character string.
Problema EntityFunctions.CreateDateTime con leap Year in linq all'entità
Il mio codice è il seguente nel mio asp.net mvc (C#) applicazione:
from u in _entities.tt_Users
let _start_date = u.Start_Date
let _startDate = _start_date.Day
let _startmonth = _start_date.Month
let _startyear = _start_date.Year
let _starthour = u.Start_Time.Value.Hours
let _startminutes = u.Start_Time.Value.Minutes
let _startseconds = u.Start_Time.Value.Seconds
let _startDateWithTime = EntityFunctions.CreateDateTime(_startyear, _startmonth, _startDate, _starthour, _startminutes, _startseconds)
let _startDateWithZeroTime = EntityFunctions.CreateDateTime(_startyear, _startmonth, _startDate, 0, 0, 0)
let _start_datetime = u.Is_Include_Time ? _startDateWithZeroTime : _startDateWithTime
let _end_date = u.End_Date
let _endDate = _end_date.Day
let _endmonth = _end_date.Month
let _endyear = _end_date.Year
let _endhour = u.End_Time.Value.Hours
let _endminutes = u.End_Time.Value.Minutes
let _endseconds = u.End_Time.Value.Seconds
let _endDateWithTime = EntityFunctions.CreateDateTime(_endyear, _endmonth, _endDate, _endhour, _endminutes, _endseconds)
let _endDateWithZeroTime = EntityFunctions.CreateDateTime(_endyear, _endmonth, _endDate, 0, 0, 0)
let _end_datetime = u.Is_Include_Time ? _endDateWithZeroTime : _endDateWithTime
let _cur_Start_date = u.Is_Include_Time ? _userStartDate : _gMTStartDate
let _cur_End_date = u.Is_Include_Time ? _userEndDate : _gMTEndDate
where u.User_Id == 1 && !u.Is_Deleted
&& _start_datetime >= _cur_Start_date && _end_datetime <= _cur_End_date
select new
{
u.User_id,
u.User_Name,
u.Login_Name,
u.Email_Address
};
Qui _userStartDate, _userEndDate, _gMTStartDate e _gMTEndDate sono parametri da mia funzione.
Se la colonna "Is_Include_Time" è vera, quindi devo includere TimeSpan anche dalla tabella. Ma per l'anno bisestile ha lanciato l'errore.
Qualche suggerimento?
La sua non è andare a lavorare nel mio caso, perché ho bisogno di confrontare con la data e l'ora in il database. Qualche altra alternativa? – Prasad
