Today’s TechTip is a two-for-one. I’ll talk about SQL’s OVRDBF replacement, ALIAS, and a simple yet dangerous SQL statement, DROP. Keep reading to find out more.
By Rafael Victória-Pereira
Let’s start with ALIAS. In a nutshell, we can say that ALIAS is Override Database File (OVRDBF) made simple, practical, and permanent.
If you ever used the OVRDBF CL command, then the functionality provided by ALIAS should be easy to grasp; it’s exactly the same! If you never used OVRDBF, it’s a way to use an alternate name for a file or, most importantly, a member of a file. This is especially important because you can’t specify a file member in SQL. The file member concept is an IBM i peculiarity, and SQL has no idea how to handle it. Fortunately, the CREATE ALIAS SQL instruction allows you to create a name for a given member of a file.
Learn how to use a prototyped call, an alternative to an ILE RPG sub-procedure, to call one program from another
by David Shirey
Editor’s Note: This article is excerpted from chapter 8 of 21st Century RPG: /Free, ILE, and MVC, by David Shirey.
In some situations, when using an ILE sub-procedure in your program, you may want to write the sub-procedure up as a small program and then call it from another program. Granted, that is not technically a sub-procedure, but we will let that go for the moment and concentrate on the call of one program by another.
IT managers hoping to find new IBM i talent are discovering that the pool of experienced RPG programmers and operators or administrators with intimate knowledge of the operating system and the applications that run on it is small.
This begs the question: How will you manage the platform that supports such a big part of your business?
This guide offers strategies and software suggestions to help you plan IT staffing and resources and smooth the transition after your AS/400 talent retires. Read on to learn:
- Why IBM i skills depletion is a top concern
- How leading organizations are coping
- Where automation will make the biggest impact

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.
Have you been wondering about Node.js? Our free Node.js Webinar Series takes you from total beginner to creating a fully-functional IBM i Node.js business application.
Part 1 will teach you what Node.js is, why it's a great option for IBM i shops, and how to take advantage of the ecosystem surrounding Node.
In addition to background information, our Director of Product Development Scott Klement will demonstrate applications that take advantage of the Node Package Manager (npm).
Can you trust all of your users all of the time?
A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six month later.
A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
- How phishing attacks are becoming more sophisticated
- Three little-known ways malicious programs can reach your IFS
- Why the IFS is IBM i’s “Typhoid Mary”
You’ll also learn why some of the most common malware solutions still leave IBM i systems vulnerable—and what you can do to protect your organization.
