Creating APEX report with rolling set of columns #JoelKallmanDay The last several years I've participated in the Joel Kallman Day tributes with articles about SQL and PL/SQL. While there are no requirements for article topics, this year I wanted to contribute something within the framework Joel was best known for... APEX. Many reports aggregate data over time periods and will usually return different dates and times as distinct rows. In some reports though, it is more useful to show a rolling window of time. https://seanstuber.com/2025/10/15/creating-apex-report-with-rolling-set-of-columns-joelkallmanday/
