Sequel::AdapterNotFound: LoadError: cannot load such file -- win32ole

Question

I am successfully able to connect to MySQL and Postgres database using 'sequel'.

I want to connect to the SQL Server database from Ubuntu 12.04 to Windows machine. Using tiny-tds we can do that, but I want to use 'sequel' for connection

Gem Installed

gem 'dbi'
gem 'tiny_tds'
gem 'sequel'
gem "win32ole-pp"
gem "rubysl-win32ole"
gem 'activerecord-sqlserver-adapter'

I am getting following error.

1.9.3p448 :007 >   require 'win32ole-pp'
LoadError: cannot load such file -- win32ole-pp

1.9.3p448 :008 > require 'rubysl-win32ole'
 => false 

1.9.3p448 :001 > DB = Sequel.ado(:database => 'test_database', :host => 'xxx.xxx.xxx.xxx', :user => 'username', :password => 'password', :provider => 'SQLNCLI10')
    Sequel::AdapterNotFound: LoadError: cannot load such file -- win32ole

Sequel provides adapter for tiny tds. How I can use that adapter? Please tell me how I can do that with sequel gem?

I am not getting how to use tiny tds with sequel, as sequel is providing adapter for tiny_tds.

Thank you...

Finally I am able to connect to remote MSSQL database from ubuntu 12.04 machine with help of sequel. Sequel uses tiny_tds for connecting to SQL server database. Here xxx.xxx.xxx.xxx is ip address of remote machine. No need for win32ole

Sequel provide adapter for MySQL2, Postgres, SQL Server and Tiny tds.

Gem Required

gem 'tiny_tds' #For SQlServer
gem 'mysql2' #For MySQL
gem 'sequel'

If you are connecting to MySQL2

DB = Sequel.connect(:adapter => 'mysql2', :user => 'username', :password => "passw0rd", :host => "xxx.xxx.xxx.xxx" , :database => "test_database")

If you are connecting to SQL Server

DB = Sequel.connect(:adapter => 'tinytds', :user => 'username', :password => "passw0rd", :host => "xxx.xxx.xxx.xxx" , :database => "test_database")

post = DB.from(:test_table)
