Sybase IQ JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Sybase IQ.



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

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

Configure a JDBC Connection to Sybase IQ 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 IQ\lib).

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

To connect to SybaseIQ, set User, Password, Server and Database properties. To secure connections with TLS/SSL, set UseSSL to TRUE.

Built-in Connection String Designer

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

java -jar cdata.jdbc.sybaseiq.jar

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

Below is a typical JDBC connection string for Sybase IQ:

jdbc:sybaseiq:User=myuser;Password=mypassword;Server=localhost;Database=Northwind

Create a JRuby App with Connectivity to Sybase IQ Data

Create a new Ruby file (for example: SybaseIQSelect.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 IQ 2018/lib/cdata.jdbc.sybaseiq.jar' url = "jdbc:sybaseiq:User=myuser;Password=mypassword;Server=localhost;Database=Northwind" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT ProductName, Price 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 IQ data with JRuby. To do so, simply run your file from the command line:

jruby -S SybaseIQSelect.rb
