Question

I would like to simply query table Flights, contains datetime field Arrival, and group results by date, then add paging using linq to entity.

How can we group flights by arrival dates?

Answer 1

Since you’re looking for something simple, try this out.

int recordsPerPage = 10, currentIndex = 0;
var groupQuery =
    myDC.Flights.
    GroupBy(f => EntityFunctions.TruncateTime(f.Arrival)).
    Skip(recordsPerPage * currentIndex).
    Take(recordsPerPage);

This will give you back groups of Flight objects which you can use however you plan.
