Connect to QuickBase Data in Ruby

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

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

Create an ODBC Connection to QuickBase 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.

User Authentication Method

To authenticate with user credentials, specify the following connection properties:

  1. Set the User and Password.
  2. If your application requires an ApplicationToken;, you must provide it otherwise an error will be thrown. You can find the ApplicationToken under SpecificApp > Settings > App management > App properties > Advanced settings > Security options > Manage Application Token.

User Token Authentication

To authenticate with a user token, specify the following connection properties:

  1. Set UserToken and you are ready to connect. You can find the UserToken under Quick Base > My Preferences > My User Information > Manage User Tokens.

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 QuickBase Data

Create a new Ruby file (for example: QuickBaseSelect.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 QuickBase Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = '100'") #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 QuickBase data with Ruby. To do so, simply run your file from the command line:

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