If you DO NOT specify a $orderby or $top option, then the results from OData will be listed in the order the items were inserted into the database? So let me get this straight.

In SqlServer, using select top does not force a sort. Hi Marcelo,

The idea behind this decision is that we wanted clients to be able to 'scan' a complete feed by using a series of $top/$skip requests, but to do that we need to guarantee that the results are ordered by *something*. So if there isn't an $orderby option, the system orders by primary key (which will give a stable order to all entries). Just wanted to drop a note and confirm that this is indeed the case.
