How do I perform Date Comparison in EF query?

Use the class DbFunctions for trimming the time portion.

using System.Data.Entity;

var bla = (from log in context.Contacts
           where DbFunctions.TruncateTime(log.ModifiedDate) 
                              ==  DbFunctions.TruncateTime(today.Date)
           select log).FirstOrDefault();

That should work. Are you sure that there isn't another part of the query that triggered the exception? I have several instances of queries of the form

var query = from e in db.MyTable
            where e.AsOfDate <= DateTime.Now.Date
            select e;

in my code.


It may be due to the date in the database being nullable. Try this:

var EmployeeName =
from e in db.employee
where e.StartDateColumn.Value <= startDT 

You can check the condition like this

var nextDay = DateTime.Today.AddDays(1);

var query = from e in db.MyTable
            where e.AsOfDate >= DateTime.Today && e.AsOfDate < nextDay 
            select e;

here you'll get the records on AsOfDate date as we checking between today(00:00:00) and tommorow(00:00:00) we'll get today's date record only what ever may be the time...
