DDL-defined tables are very good about handling null values, but sometimes we still need to deal with them in DDS-defined files as well; this article shows the RPG techniques required to do that.
By Joe Pluta
When you create a table in SQL using DDL statements, the default is to allow nulls, which means that, for any row, you can populate the column with a null value. Nulls have a number of specific characteristics; you can read about them here. We won't go into those issues in detail, although they can be quite interesting. The issue of nulls in WHERE clauses is particularly fascinating but not relevant to our discussion. Instead, today we're going to see how to support null result values in more-traditional RPG and DDS settings.
This year, why not give a gift to others and contribute to the IBM i community?
By Brian May
It has been quite a while since I wrote about favorite gifts from IBM. A little over a year ago, I wrote gifts to give yourself. Now, in true trilogy form, because the best things come in threes, I am writing the last article in the gifts series. I guess that means I will need a new themed series.
Live Webinar: Make Modern Apps You'll Love with
Mobile computing is rapidly maturing into a solid platform for delivering enterprise applications. Many IBM i shops today are realizing that integrating their IBM i with mobile applications is the fast path to improved business workflows, better customer relations, and more responsive business reporting. The ROI that mobile applications can produce for your business is substantial.
This ASNA whitepaper takes a look at mobile computing for the IBM i. It discusses the different ways mobile applications may be used within the enterprise and how ASNA products solve the challenges mobile presents. It also presents the case that you already have the mobile programming team your projects need: that team is your existing RPG development team!

The annual Profound Logic ‘State of IBM i Modernization Survey” takes a look at the trends and attitudes that shape the IBM i modernization market. We reached out to the IBM i community, and the response was outstanding: close to 800 people, nearly 300 more than last year, took the survey. This enthusiasm resulted in very interesting findings for how businesses plan to use and modernize the platform in the coming year.
As you read through each section of the survey, you will see our summary of the results and suggestions for the future. We hope the survey will help your business better understand what is possible for your IBM i platform in the coming year.
IBM i skills depletion is a top concern for IBM i shops around the world. The strategies you discover in this webinar will help you ensure that your system of record—your IBM i—continues to deliver a powerful business advantage, even as staff retires.

Here's how to create descriptive table and column names that make DB2 for i easier for end users to navigate
by Rafael Victoria-Pereira
Editor's note: This article is excerpted from chapter 4 of SQL for IBM i: A Database Modernization Guide, by Rafael Victoria-Pereira.
Chapter 3 led us on the first step toward a true database, but it kept most of the hallmarks that make a DB2/400 database very "user-unfriendly": the table and column names are short, in the typical and old-fashioned way of the AS/400. However, end users' demands in regard to data queries have evolved significantly in recent years. The users of our UMADB are particularly data-hungry and are overtaxing the university's IT staff labor resources. This added burden on the IT staff is something that often occurs when you "open up" the database to the end users. The problem is that the database is not always ready to be used by someone not used to short, cryptic names, and this ends up causing additional stress on the IT staff, because it requires additional time…
