Defined in:

lib/sequel/sql.rb

Overview

If on 1.9, create a Sequel::BasicObject class that is just like the default BasicObject class, except that missing constants are resolved in Object. This allows the virtual row support to work with classes without prefixing them with ::, such as:

DB[:bonds].filter{maturity_date > Time.now}
