Connect to Salesforce Einstein Data in JRuby

Create a simple JRuby app with access to live Salesforce Einstein data.

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

Configure a JDBC Connection to Salesforce Einstein 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 Salesforce Einstein\lib).

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

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

See the Getting Started section of the CData data provider 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 Salesforce Einstein JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.sfeinsteinanalytics.jar

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

Below is a typical JDBC connection string for Salesforce Einstein:

jdbc:sfeinsteinanalytics:OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Salesforce Einstein Data

Create a new Ruby file (for example: SFEinsteinAnalyticsSelect.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 Salesforce Einstein 2018/lib/cdata.jdbc.sfeinsteinanalytics.jar' url = "jdbc:sfeinsteinanalytics: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 (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SFEinsteinAnalyticsSelect.rb

Writing SQL-92 queries to Salesforce Einstein allows you to quickly and easily incorporate Salesforce Einstein data into your own JRuby applications. Download a free trial today!
