I am sorry about opening a new ticket.  The previous one has been closed, and I discovered something different.  Below is the description of the problem:

The definition of the table is:

CREATE TABLE "Order" ("Id" bigint PRIMARY KEY  NOT NULL , "Date" DATETIME NOT NULL , "Type" varchar(8) NOT NULL )

I ran some more tests with how the date is created.  I found that how the date is created (in place or as a variable) instead of the syntax style caused the behavior difference.

// query 1 - passed, returned 2
var c = db.Orders.Where(i => i.Date == new DateTime(2014, 5, 23)).Count();

// query 2 - failed, returned 0
var date = new DateTime(2014, 5, 23);
var c = db.Orders.Where(i => i.Date == date).Count();

Same behavior for both styles and both DATE and DATETIME sql type.
