Sequel version 0.3.1 has just been released. This release includes an experimental Oracle adapter, better Database#fetch functionality, and other minor bug fixes and improvements. Following is a discussion of the changes: === Preliminary Oracle adapter Sequel now includes an Oracle adapter, based on the 'oci8' library. To connect to an Oracle adapter you can supply a URL: require 'sequel/oracle' DB = Sequel('oracle://user:password@my_db') # or DB = Sequel('oracle://user:password@server1/my_db') Or use the Sequel.oracle method: require 'sequel/oracle' DB = Sequel.oracle('my_db', :user => 'user', :password => '******') Please note that this adapter was not tested (since I do not have access to an Oracle database) and may require some patching before it is actually usable. So if anyone is willing to do the testing that would help tremendously. === A better Database#fetch Sequel 0.3 introduced a new way to fetch records using arbitrary SQL, using Database#fetch (and the shortcut using DB#[]). Instead of returning an enumerator, this method now returns a dataset modified to always execute the same SQL statement, letting you treat it just like a normal Dataset instance: DB['SELECT * FROM items'].print DB['SELECT * FROM items'].all DB['SELECT * FROM items'].map(:id) DB['SELECT * FROM items'].to_hash(:id, :name) === Other improvements and bug fixes * More documentation for Sequel models. * Deprecated Model#pkey. Implemented better Model#pk method. * foreign_key definitions now accept :key option for specifying the remote key (#73). * Sequel now requires ParseTree version 2.0.0 or later (#74). * Fixed string literalization in mysql adapter for strings with comment backslashes in them (#75). * Changed postgres adapter to use the ruby-postgres library's type conversion if available (#76). * Fixed Model#method_missing to not raise error for columns not in the table but for which a value exists (#77). * Fixed YAML serialization (#78). * Fixed miscellaneous typos. === More info Sequel project page: <http://code.google.com/p/ruby-sequel> Sequel documentation: <http://sequel.rubyforge.org> Join the Sequel-talk group: <http://groups.google.com/group/sequel-talk> Install the gem: sudo gem install sequel Or check out the source and install manually: svn co http://ruby-sequel.googlecode.com/svn/trunk sequel cd sequel rake install
