Google Calendars ODBC Driver

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

Access Google Calendars data like you would a database, including Calendars, Events, Attendees, etc. through a standard ODBC Driver interface.



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

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

Create an ODBC Connection to Google Calendar 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.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

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 Google Calendar Data

Create a new Ruby file (for example: GoogleCalendarSelect.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 GoogleCalendar Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Summary, StartDateTime FROM VacationCalendar") #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 Google Calendar data with Ruby. To do so, simply run your file from the command line:
