Connect to Tableau CRM Analytics Data in JRuby

Create a simple JRuby app with access to live Tableau CRM Analytics data.

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Tableau CRM Analytics makes it easy to integrate connectivity to live Tableau CRM Analytics data in JRuby. This article shows how to create a simple JRuby app that connects to Tableau CRM Analytics data, executes a query, and displays the results.

Configure a JDBC Connection to Tableau CRM Analytics Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Tableau CRM Analytics\lib).

JRuby natively supports JDBC, so you can easily connect to Tableau CRM Analytics and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

Tableau CRM Analytics uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with Tableau CRM Analytics.

See the Getting Started section of the Help documentation for an authentication guide.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Tableau CRM Analytics JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.tableaucrm.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for Tableau CRM Analytics:


Create a JRuby App with Connectivity to Tableau CRM Analytics Data

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

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for Tableau CRM Analytics 2018/lib/cdata.jdbc.tableaucrm.jar' url = "jdbc:tableaucrm:OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, CloseDate FROM Dataset_Opportunity") while ( do puts rs.getString(1) + ' ' + rs.getString(2) end

With the file completed, you are ready to display your Tableau CRM Analytics data with JRuby. To do so, simply run your file from the command line:

jruby -S TableauCRMSelect.rb
