LINQ 2 Entities , howto check DateTime.HasValue within the linq query

Question

I have this method that is supposed to get the latest messages posted, from the Table (& EntitySet) called ENTRY

///method gets \"days\" as parameter, used in ne

Answer 1

What do you want to do in case DATECREATED is null?

If you just want to ignore these records use an additional condition(or where clause):

var entries = from ent in db.ENTRY
              where ent.DATECREATED.HasValue && ent.DATECREATED.Value > ...

Answer 2

Well... you can exclude entries with DATECREATED equal to null by simply using

entries = from ent in db.ENTRY 
          where ent.DATECREATED != null
          where ent.DATECREATE.Value > DateTime.Today....

and include them with

  entries = from ent in db.ENTRY 
          where ent.DATECREATED == null ||
                ent.DATECREATE.Value > DateTime.Today.....

I am not sure though if the second query actually stops checking the where clauses once the first condition is true.
