Ruby tool to support Database versioning, look like this can work independence from Ruby on Rails - http://www.google.com/search?hl=en&lr=&q=Ruby+Rails+Migrations&btnG=Search
An example coding with this tool - http://rails.aizatto.com/2007/05/27/activerecord-migrations-without-rails/ http://wiki.rubyonrails.org/rails/pages/UnderstandingMigrations

Eclipse plugin - http://dbcopy.sourceforge.net/en/dbcopy/index.html but I cannot get it working, instead, http://dbcopyplugin.sourceforge.net/ work a lot better. However it is better to install using installation jars (and source) of SQuirreL, otherwise there may be version not map issue.

Another new tool, migrate4j - http://karussell.wordpress.com/2009/12/23/simple-database-migration-in-java/
