But when you use find_by_sql, is there a way to do this? You could definitely write the find_by_sql SQL to join Foo and Bar tables: Foo.find_by_sql("SELECT foo.*, bar.* from foo, bar where foo.bar_id = bar.id") But is there a

Hi, I''d like to do a "find_by_sql" without a model (e.g. <model name>.find_by_sql("...")) as the results I get back are a once off special, and I''m happy to handle them as an array.
