Fluent NHibernate does not create IN part of WHERE clause

Question

I have Fluent NHibernate Linq queries where I check values based on run time arrays. A basic example would be something like:

var array = [1,2,3,4,5,6];
usin         


        

Answer 1

Use Any:

 return session.Query().Where(x => array.Any(y => y == x.CompareVal)).ToList();

Your repository pattern (using plain Func) automatically materializes your query to list, if you want something to be deferredly executed, use IQueryable, don't use Func only

Something to note - I have a Generic Repository class that all of these calls are funneled through. The Query method is as follows:

public IList Query(Func criteria)
{
  using (var session = SessionProvider.SessionFactory.OpenSession())
  {
    return session.Query().Where(criteria).ToList();
  }
}

Your repository just mimic what is already provided out of the box by NHibernate
