We recently received a monster (in a great way!!) of a tech tip from Nic Guzaldo, a self-taught Pentaho expert and supporter. I spent a day or so getting my head around what Nic had accomplished (with many exclamations of "wow, I didn't know we could do THAT!"), and figured I should break it up into a series of articles for easier consumption.
This first article of the series focuses on creating a query that will not only demonstrate setting up regular data for a cross tab report, but also use user input to determine the number of columns in the query.
In the second half of this solution, we will continue with Nic's example and use the generated resultset as input to a dynamically generated report spec, to create a Pentaho report that allows a variable number of columns, dynamically generated report name, nice output names for external files and other goodies!
Start test driving this jam-packed solution at here.

- I have been in the Big Data, Business Analytics and Java development space for twenty years. I started out as a data warehouse developer for a small insurance company in the Midwest, worked for Hyperion Solutions as a software engineer for a number of years, and came in on the ground floor with the guys at Pentaho. I have a history of moving around, so I have enjoyed working with the community, consulting directly with Pentaho customers and partners and coding with the development team. I am now an Enterprise Architect and consultant for Pentaho, working on various projects.
