I have code like this: 

   require 'mysql2'

    You can use last_id method of the client instance:

    client = Mysql2::Client.new(:host => "localhost", :username => "root", :password => "", :database => "db")
insert = client.query "INSERT INTO test (name, date) VALUES ('name', '2011-11-28 09:13:56')"
id = client.last_id

    http://rubydoc.info/gems/mysql2/0.2.6/Mysql2/Client:last_id

    Edit: it doesn’t answer your original question but still looks better than call for LAST_INSERT_ID
