Sybase (dbd_sybase)
this DBD is currently outdated and will not work with DBI versions > 0.0.4 !!!
See <URL:http://www.ruby-projects.org/dbi/dbi/ChangeLog.html>.
See <URL:http://www.ruby-projects.org/dbi/dbi/ToDo.html>.
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.
Latest development snapshot available at <URL:http://www.ruby-projects.org/downloads/dbi/ruby-dbi-all-current.tar.gz>.
<URL:http://www.ruby-projects.org/downloads/dbi/ruby-dbi-all-0.0.9.tar.gz>
<URL:http://www.ruby-projects.org/downloads/dbi/ruby-dbi-all-0.0.8.tar.gz>

<URL:http://www.ruby-projects.org/downloads/dbi/ruby-dbi-all-0.0.5.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
.
There is also a mailing-list for DBI-specific discussions, see <URL:http://groups.yahoo.com/group/ruby-dbi-talk>
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://www.ruby-projects.org/dbi/dbi/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://www.ruby-projects.org/dbi/dbi/DBD_SPEC.html>.
Examples can be found in the examples/ subdirectory. There is e.g. sqlsh.rb, which is an interactive SQL shell similar to Perl's dbish.rb. Further there is in this directory the file proxyserver.rb which has to be run if you use the DBD::Proxy, to access databases remote over a TCP/IP network.
