Connect to SAS Data Sets Data in JRuby


Create a simple JRuby app with access to live SAS Data Sets data.

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

Configure a JDBC Connection to SAS Data Sets 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 SAS Data Sets\lib).

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

Set the following connection properties to connect to your SAS DataSet files:

Connecting to Local Files

  • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
  • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

Connecting to Cloud-Hosted SAS DataSet Files

While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

Built-in Connection String Designer

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

java -jar cdata.jdbc.sasdatasets.jar

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

Below is a typical JDBC connection string for SAS Data Sets:

jdbc:sasdatasets:URI=C:/myfolder;

Create a JRuby App with Connectivity to SAS Data Sets Data

Create a new Ruby file (for example: SASDataSetsSelect.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 SAS Data Sets 2018/lib/cdata.jdbc.sasdatasets.jar' url = "jdbc:sasdatasets:URI=C:/myfolder;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT name, borough FROM restaurants") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SASDataSetsSelect.rb
