Module Sequel::MySQL
In: lib/sequel/adapters/mysql.rb
lib/sequel/adapters/shared/mysql.rb

Module for holding all MySQL-related classes and modules for Sequel.

A class level convert_invalid_date_time accessor exists if the native adapter is used. If set to nil or :nil, the adapter treats dates like 0000-00-00 and times like 838:00:00 as nil values. If set to :string, it returns the strings as is. It is false by default, which means that invalid dates and times will raise errors.

  Sequel::MySQL.convert_invalid_date_time = true

Sequel converts the column type tinyint(1) to a boolean by default when using the native MySQL adapter. You can turn off the conversion to use tinyint as an integer:

  Sequel.convert_tinyint_to_bool = false
