How to query last 'n' number of records from a table?

Question

I'm using an Azure mobile service with a C# back end for my app, but I'm not sure how to query the last 16 records that were added to the DB.

I've come across the statement, and I thought that could query the "last" 16 records but it doesn't:

var result = await itemModelTable
                .Take(16)
                .ToListAsync();

Does anyone have an idea how to form this query?

Answer 1

There is no concept of Last , You need to order your collection and then use Take like:

var result = await itemModelTable
                .OrderByDescending(r=> r.SomeField)
                .Take(16)
                .ToListAsync();

For "Last", you need to use OrderByDescending and then use Take .

If no order is specified, then the records returned could be in any order. Same like SQL Select statement without order by clause.
