As far as I know, the reason for :include is mainly for eager loading.
If you know you will be querying the sections table for the companies
you are finding, doing an :include will retrieve those sections in one
query, ie, one trip to the DB. If you don't pass in the :include

OK.
I figured out that join is actually doing an inner join which
filters the rows that don't have association.
And include is actually doing an 'outter join' which shows all the
rows from tables.
But, however, I still can not figure out why that strange SQL
statement comes out.
