Module: Sequel::Plugins::UnlimitedUpdate

Defined in:

lib/sequel/plugins/unlimited_update.rb

Overview

The unlimited_update plugin is designed to work around a MySQL warning in replicated environments, which occurs if you issue an UPDATE with a LIMIT clause. No other database Sequel supports will create an UPDATE clause with a LIMIT, and in non-replicated MySQL environments, MySQL doesn’t issue a warning. Note that even in replicated environments the MySQL warning is harmless, as Sequel restricts an update to rows with a matching primary key, which should be unique.

Usage:

# Make all model subclass not use a limit for update
Sequel::Model.plugin :unlimited_update

# Make the Album class not use a limit for update
Album.plugin :unlimited_update
