Set-based processing in SQL is very powerful, but sometimes you have to do a little extra work to use it.
By Joe Pluta
I've used various features of SQL for a long time, but the one that has always given me a little trouble is the PREPARE statement. I use it rarely enough that I usually have to remind myself how to do it (and why!). I thought I'd write this article as a way to remind myself and you of how and when to use the PREPARE statement and its close cousins, the EXECUTE and EXECUTE IMMEDIATE statements.
It’s time to start discussing modernizing your IBM i applications. This new subseries of RPG Academy presents some questions to ask yourself and offers some answers.

The “modernization” buzzword has been making the rounds for quite a while, but it has gained traction in recent years among the IBM i community, due to the advent of mobile computing, more-demanding users, and the whole cloud computing paradigm. This and the next few TechTips of this subseries will discuss the different facets of this fuzzy buzzword from my point of view.
After surveying 500+ IBM i professionals, we discovered:
- The state of IBM i modernization in today's businesses and their goals for the future

Several times so far, we have mentioned that one of the reasons for going to ILE is to have more control over the application and how it runs. And nothing exemplifies this more than the use of activation groups.
