Author of Ruby/DBI; wrote the DBI and most of the DBDs (except DBD::Pg).
Author of Ruby/DBI 0.0.4 from which many good ideas were taken into the new completely rewritten version 0.0.5.
Author of the PostgreSQL driver (DBD::Pg). Wrote many additional code (e.g. sql.rb, testcases). Gave many helpful hints and comments.
Implemented DatabaseHandle#columns for Mysql and Pg.
For his version of module BasicQuote in sql.rb
For his case insensitive load_driver patch and parameter parser.
For testing the SQLRelay DBD and for his initial DBD.
Extending Oracle DBD for method columns.
Fixed bug in DBD for PostgreSQL (default values in method columns).
Fixed bug in DBD ODBC (method columns) and proxyserver.
Patch for DBD Pg (cache PGResult#result in Tuples) which increases performance by a factor around 100
Added method Statement#fetch_scroll for PostgreSQL DBD.

See <URL:http://ruby-dbi.sourceforge.net/ToDo.html>.
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.
