db is a DAL object, which is callable. Its __call__ method takes a query and returns a Set object, which has a select() method for pulling records from the database. So, typically, you would do:
db(query).select(...) However, you can call db without any query (it defaults to None), in which case, the select will simply return all records from the table specified in the select() call. So: db().select(db.image.ALL, orderby=db.image.title) returns all records in the db.image table. It is equivalent to: db(db.image.id > 0).select(db.image.ALL, orderby=db.image.title) See http://web2py.com/books/default/chapter/29/6#select.
