Question

Is there a nice succinct way to get random rows using query over? Something like this:

            .QueryOver<Stuff>(() => entity)
            .OrderBy(x => Guid.NewGuid()).Asc
            .Take(3)
            .List();

This doesn’t work unfortunately.

Check out this article:

The key, I believe, is getting the query engine to generate the random value while executing the query, rather than specifying a value from the application (which may seem random to the application, but not to the query engine).
