Hi There,
i have a very simple table with a Datetime column and i have this mapping in my domain object.
MyDate is the name of the datetime column in the DB.
public virtual int Day { get; set; }
public virtual int Month { get; set; }
public virtual int Year { get; set; }
public virtual int Hour { get; set; }
public virtual int Minutes { get; set; }
public virtual int Seconds { get;set; }
public virtual int WeekNo { get; set; }
Map(x => x.Day).Formula("DATEPART(day, Datetime)");
Map(x => x.Month).Formula("DATEPART(month, Datetime)");
Map(x => x.Year).Formula("DATEPART(year, Datetime)");
Map(x => x.Hour).Formula("DATEPART(hour, Datetime)");
Map(x => x.Minutes).Formula("DATEPART(minute, Datetime)");
Map(x => x.Seconds).Formula("DATEPART(second, Datetime)");
Map(x => x.WeekNo).Formula("DATEPART(week, Datetime)");
This is working all great .... but Week Datepart.
I saw with NHProf the sql generating for a select and here's the problem it's generating all the sql correctly but for week datepart.. this is part of the SQL generated:
....Datepart(day, MyDate) ... ....Datepart(month, MyDate) ... ....Datepart(year, MyDate) ... ....Datepart(hour, MyDate) ... ....Datepart(minute, MyDate) ... ....Datepart(second, MyDate) ... ....Datepart(this_.week, MyDate) ...
where this_ is the alias for the table that nhibernate uses.
so it's treating the week keyword for the datepart stuff as a column or something like that. To clarify there's no column or properties that is called week.
some help ?
cheers
Alessandro
