Connect to Microsoft Project Data in Ruby

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

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

Create an ODBC Connection to Microsoft Project 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.

The User and Password properties, under the Authentication section, must be set to valid Microsoft Project user credentials. In addition, you will need to specify a URL to a valid Microsoft Project server organization root or Microsoft Project services file.

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 Microsoft Project Data

Create a new Ruby file (for example: MicrosoftProjectSelect.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 MicrosoftProject Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT ProjectName, ProjectActualCost FROM Projects") #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 Microsoft Project data with Ruby. To do so, simply run your file from the command line:

ruby MicrosoftProjectSelect.rb Writing SQL-92 queries to Microsoft Project allows you to quickly and easily incorporate Microsoft Project data into your own Ruby applications. Download a free trial today!
