I’m writing a log parser for an asp.net mvc2 web application. I use Entity framework as a model and logging is done both using my manual engine together with SqlServer2008 CDC feature.

When inserting, or editing a row in a database, the action is being logged. However, there’s a small lag between occuring changes in actual table and logging those changes. I need to display details from CDC tables, when user clicks on some of them. Because of before mentioned lag, I can not compare equivalence of two DateTime values. I want to allow lag of 2000 miliseconds. Easiest way I know is using Ticks, or TimeOfDay and comparing absolute value of their values subtracted, but damned Linq-To-Entities does not allow these two properties.

Here’s the simple function I’m having problems with…

        public static List<dbo_Object_CT> GetLogDetails (Int32 objectID, DateTime? actionDateAndTime)
    {
        ObjectEntities oe = new ObjectEntities();

        var mylogdetails = (from objectLog in oe.dbo_Object_CT
                     join ltm in oe.lsn_time_mapping on objectLog.C___start_lsn equals ltm.start_lsn
                     where (objectLog.Id == objectID)
                     && ((actionDateAndTime == null) ? true : (Math.Abs(actionDateAndTime.Value.Ticks - ltm.tran_begin_time.Value.Ticks) < 2000))
                     select objectLog).ToList();

        return mylogdetails;
    }

I know I could manually do “where” clause, but it would be big, ugly and slow. Does anyone have better sugestions?
