Ruby/DBI is available for from the SourceForge project page.
If you're running FreeBSD or NetBSD, have a look at their package collections. FreeBSD has for DBI and each DBD an easy to install package, NetBSD currently only for PostgreSQL but more is to come.
A NetBSD package for MySQL is available at <URL:http://www.fantasy-coders.de/ruby/ruby-mysql-2.4.tar.gz>.
All available DBDs come with this package, but you should only install the DBDs you really need.
ruby setup.rb config ruby setup.rb setup ruby setup.rb install
ruby setup.rb config --with=dbi,dbd_pg.... ruby setup.rb setup ruby setup.rb install
Choose the packages to install by specifing them after the option --with
.
A mailinglist for DBI-specific discussions is available from the SourceForge project page.
Our former mailing-list was at <URL:http://groups.yahoo.com/group/ruby-dbi-talk>; please, don't use it!
See the directories lib/*/doc or ext/*/doc for DBI and DBD specific informations.
The DBI specification is lib/dbi/doc/DBI_SPEC or lib/dbi/doc/html/DBI_SPEC.html or available from WWW at <URL:http://ruby-dbi.sourceforge.net/DBI_SPEC.html>.
The DBD specification (how to write a database driver) is lib/dbi/doc/DBD_SPEC or lib/dbi/doc/html/DBD_SPEC.html or available from WWW at <URL:http://ruby-dbi.sourceforge.net/DBD_SPEC.html>.
The SQL command line interpreter sqlsh.rb is available in directory bin/commandline. It gets installed by default.
Examples can be found in the examples/ subdirectory. In this directory there is the file proxyserver.rb which has to be run if you use the DBD::Proxy, to access databases remote over a TCP/IP network.
