Connect to Sybase Data in JRuby

Create a simple JRuby app with access to live Sybase data.

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

Configure a JDBC Connection to Sybase 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 Sybase\lib).

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

To authenticate with Sybase, set User and Password. Additionally, set IntegratedSecurity; to true to use Windows authentication otherwise, Sybase authentication is used. Set the Server and Database properties. To secure connections with TLS/SSL, set Encrypt to true.

Built-in Connection String Designer

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

java -jar cdata.jdbc.sybase.jar

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

Below is a typical JDBC connection string for Sybase:

jdbc:sybase:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;

Create a JRuby App with Connectivity to Sybase Data

Create a new Ruby file (for example: SybaseSelect.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 Sybase 2018/lib/cdata.jdbc.sybase.jar' url = "jdbc:sybase:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, ProductName FROM Products") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SybaseSelect.rb

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