Cannot implicitly convert type IEnumerable to IQueryable

Question

Obfuscated Scenario: A person has zero, one or many pets.

Using Linq to Sql, the need is to get an IQueryable list of pets for the given pe

Answer 1

This works for me (with different tables of course, but same relationship):

IQueryable personPets = (
   from p in db.Person
   where p.ID == somePersonID
   select p
).Single().Pets.AsQueryable();

Although I'd probably write it in some variation of this way:

var personPets = 
    db.Person.Single(t => t.Id == somePersonId).Pets.AsQueryable();
