Evernote ODBC Driver

The Evernote ODBC Driver is a powerful tool that allows you to connect with live Evernote data, directly from any applications that support ODBC connectivity.

Access Evernote like you would a database - access Notebooks, Notes, Searches, Tags, etc. through a standard ODBC Driver interface.



Connect to Evernote data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for Evernote makes it easy to integrate connectivity to live Evernote data in Ruby. This article shows how to create a simple Ruby app that connects to Evernote data, executes a query, and displays the results.

Create an ODBC Connection to Evernote Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Evernote uses the OAuth authentication standard. You can use the embedded OAuth application to connect without setting any connection properties. Alternatively, you can create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to Evernote Data

Create a new Ruby file (for example: EvernoteSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData Evernote Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Title, Author FROM Notes WHERE Guid = ab26f704-5edf-4a9f-9e4c-8da893a4acd8") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your Evernote data with Ruby. To do so, simply run your file from the command line:
