ActiveRecord::Base.sanitize_sql

sanitize sql is used for escaping custom sql built with user input.

behaviour has changed in rails 2 when compared to rails 1.2

Rails 2.1

=>nil

Rails 1.2
>>ActiveRecord::Base.sanitize_sql("")
=>""


ActiveRecord cache preference
ActiveRecord include preference

will be adding description and ticket numbers soon
