  • Guru: Creating An SQL Stored Procedure That Returns A Result Set

    May 12, 2025 Mike Larsen

    Continuing to build out the stored procedure series, I’m going to show how to create an SQL stored procedure that returns a result set. This is very similar to the previous article where I showed how to do this using RPG. In this example, we’re just using pure SQL to achieve the same results.

    I created an SQL script (Figure 1) that selects all rows from the Departments table. The SQL statement is the same as the one I used in the RPG program from the prior article, but I’ll describe it again here. I didn’t add any selection criteria …

  • Oft-Requested SQL Function Coming In IBM i 7.6

    April 8, 2025 Alex Woodie

    IBM i engineers and product managers have no shortage of feature requests to wade through, some of which make it into the platform and many of which do not. With the upcoming delivery of IBM i 7.6, IBM will be delivering one of the most often requested features: Support for UPDATE and DELETE statements in the data-change-table-reference clause of a SQL statement.

    While the capability to update and delete statements with data-change-table-reference may not sound like a big deal, it actually represents a significant improvement that will simplify database programming tasks for developers, according to Scott Forstie, IBM’s Db2 for …

  • RISE For SAP Could Be A Boon For IBM’s PowerVS Cloud

    March 17, 2025 Timothy Prickett Morgan

    German application giant System Analyse Programmentwicklung, better known as SAP, has spent more than five decades to deliver five major versions of application software to help companies run themselves. They are R/1 in 1977, R/2 in 1981, R/3 in 1992, mySAP.com (which became Business Suite) in 1999, SAP HANA in 2011 with its S/4HANA application suite in 2015. And today, the company has over 400,000 customers.

    As is well known, SAP wants to create an application system, which is a phrase that resonates with the OS/400 and IBM i faithful. SAP was founded by five ex-IBMers from Germany and started …

  • Guru: Creating An RPG Stored Procedure That Returns A Result Set

    March 17, 2025 Mike Larsen

    In the previous article, I showed how to create an RPG stored procedure that uses parameters. In this article, I’m going to show how to create an RPG stored procedure that returns a result set, as we would likely encounter this scenario more frequently. The data used in this example comes from the Department table from IBM’s Sample database.

    I created an RPG program (Figure 1) that selects all rows from the Departments table. I didn’t add any selection criteria as I know there aren’t many rows in the table, but you may want to limit the number of rows …

  • Security Top of Mind as Massive Hacks Continue

    December 4, 2024 Alex Woodie

    The calendar indicates peace and joy, but instead a sense of dread and fear permeates business, as the number and scope of security breaches grows and new regulations loom on the horizon. Ransomware, in particular, is proving itself to be a thorny issue for companies of all sizes, including IBM i shops.

    The latest mega-hack involved Chinse state actors infiltrating the American telecommunications backbone, where they not only accessed huge numbers of call detail records (CDRs) – which they used for counter-espionage purposes – but also read text messages and listened to Americans’ phone calls.

    Known as Salt Typhoon, the …

  • IBM’s Fall 2024 Code for IBM i Enhancements

    November 13, 2024 Alex Woodie

    Adoption of Code for i continues to soar among IBM i developers, as they shift from heavy, expensive integrated development environments (IDEs) to lighter, open-source options. With the latest Technology Refreshes (TRs) for IBM i, IBM is making the VS Code plug-in even more useful for RPG and COBOL developers.

    Code for IBM i is the brainchild of Liam Allan, the midrange wunderkind with an intense aversion to Rational Developer for IBM i (RDi), IBM’s Java-based flagship IDE for IBM i. As adoption of the VS Code extension grew in the summer of 2022, IBM smartly hired Allan as a …

  • Another GenAI-Powered Testing Tool Comes to IBM i

    November 6, 2024 Alex Woodie

    IBM says it’s bringing a new AI accelerator to the Power line to drive compute-hungry generative AI workloads, such as the new RPG coding assistant that it’s also developing. But IBM won’t be the only source of such GenAI-powered coding assistants, as a company called Abstracta recently announced another one.

    There’s a lot of interest in the Spyre accelerators that IBM announced earlier this year for the System z mainframe and which IBM announced last month during its TechExchange conference will be coming to Power. Considering the massive demand for Nvidia GPUs, which could plug into past generations of Power …

  • IBM Bolsters Db2 for i With Tech Refreshes

    October 23, 2024 Alex Woodie

    IBM is delivering a handful of new database capabilities with the latest batch of Technology Refreshes for IBM i 7.5 and 7.4, including new function to create Universally Unique Identifiers (UUIDs), new capabilities for the security data mart, and various enhancements to SQL-based IBM i Services.

    A UUID is a random 36-character, 128-bit alphanumeric string that can be used to identify something, such as a row or table in a database, with near certainty that the identifier is unique, has never been used before, and will never be used again.

    The UUID system was first implemented by the Open Software …

  • Surprise! It’s 2024 Fall TR Time for IBM i

    October 9, 2024 Alex Woodie

    IBM announced the Technology Refreshes (TRs) for IBM i version 7.5 and 7.4 yesterday, bringing a host of new capabilities to the proprietary operating system. As expected, the surprise update covers a range of IBM i facilities, including Db2, Navigator, ACS, PowerHA, and the development tools.

    Navigator gets several more enhancements with the new TRs, including: a new dashboard with software licensing information; Web-based administration of network facilities; support for monitoring of Java 11 and Java 17 jobs; enhancements to the Performance Data Investigator (PDI); and new options for working with audit journals, among other capabilities.

    IBM also includes the …

  • IBM Introduces Mapepire, The New Db2 For i Client

    September 9, 2024 Alex Woodie

    IBM has released a new client for connecting applications to the Db2 for i database. Dubbed Mapepire, the open source client is designed to be faster, lighter weight, and easier for developers to work with compared to existing ODBC and JDBC database clients, especially in cloud environments.

    Building an application-side database client using existing Db2 for i’s database drivers, such as ODBC and JDBC (included in the JTOpen Java toolbox for IBM i) typically entails cramming a lot of overhead into the client component, says Liam Allan, who helps develop new open source development tooling at IBM.

    “For example, jtopen …
