Essential guide for the Ruby driver

In the past couple of months, I received a fairly large number of requests about how to use the IBM_DB Ruby driver to query DB2. So I decided to create an essential guide for using the Ruby DB2 driver. Amongst the topics I covered, there are: connecting to the database (local or remote), executing queries, retrieving connection and execution errors, fetching results, using prepared statements for parameterized queries and finally how to use the driver for dealing with stored procedures. That should be more than enough to get your started with the driver and, even if it’s about Ruby and not Rails, it will be beneficial to those who develop DB2 on Rails applications.
