Hello.
I want to order a resultset from a table by two columns in another table. Here's how it looks:

[Books]
ID
Title


[linkBookAuthor]
BookID (Books.ID)
AuthorID (Authors.ID)

[Authors]
ID
Firstname
Lastname
AuthorOrder

As you can see it's a many to many relationship. Is there a way to order the books by Authors.Lastname (the first if there are several authors) with one query ? If not, what is the fastest way ? I don't need the names in the resultset so I only want to order the books by Authors.Lastname, not include Authors.Lastname.

Thanks for any help.
