Iceland, Iceland, Baby

Alright, stop!  Collaborate and listen!  Ok, I’ll be the one to take my own advice here and stop...

Later this month, I’ll be heading to Reykjavík, Iceland to deliver our 3-day training class “Developing Desktop APEX Applications”.  This class will be open to the public and costs about $2500 per student, so anyone is welcome to sign up. You’ll have to make your way to Iceland, of course.

Here’s a brief overview of what we’re going to cover:

This 3-day course is an introduction to developing web applications using Oracle Application Express, or simply APEX. The course starts out with an overview of data model of the application that student will build. It then transitions to the SQL Workshop portion of APEX, where basic database object management concepts are addressed.

The bulk of the remainder of the class focuses on building an APEX application, starting with the core components that make up the foundation of the application. Students will then build several forms and reports, which allow user interaction with the data. Next, additional types of forms and reports will be introduced, as well as more advanced techniques used when managing them. The course will conclude with a review of the basic security attributes of an application as well as how to prepare and deploy it to a production environment.

The course will run from March 28th through March 30th, and will be held in a location TBD in Reykjavík. More details, as well as the course outline and a link to register can be found on Miracle’s site here: http://miracle.is/en/building-apex-applications/

Custom Export to CSV

It's been a while since I've updated my blog. I've been quite busy lately, and just have not had the time that I used to. We're expecting our 1st child in just a few short weeks now, so most of my free time has been spent learning Lamaze breathing, making the weekly run to Babies R Us, and relocating my office from the larger room upstairs to the smaller one downstairs - which I do happen to like MUCH more than I had anticipated. I have everything I need within a short walk - a bathroom, beer fridge, and 52" HD TV. I only need to go upstairs to eat and sleep now, but alas, this will all change soon... Recently, I was asked if you could change the way Export to CSV in ApEx works. The short answer is, of course, no. But it's not too difficult to "roll your own" CSV export procedure. Why would you want to do this? Well, the customer's requirement was to manipulate some data when the Export link was clicked, and then export it to CSV in a forma

Refreshing PL/SQL Regions in APEX

If you've been using APEX long enough, you've probably used a PL/SQL Region to render some sort of HTML that the APEX built-in components simply can't handle. Perhaps a complex chart or region that has a lot of custom content and/or layout. While best practices may be to use an APEX component, or if not, build a plugin, we all know that sometimes reality doesn't give us that kind of time or flexibility. While the PL/SQL Region is quite powerful, it still lacks a key feature: the ability to be refreshed by a Dynamic Action. This is true even in APEX 5. Fortunately, there's a simple workaround that only requires a small change to your code: change your procedure to a function and call it from a Classic Report region. In changing your procedure to a function, you'll likely only need to make one type of change: converting and htp.prn calls to instead populate and return a variable at the end of the function. Most, if not all of the rest of the code can rem

Logging APEX Report Downloads

A customer recently asked how APEX could track who clicked “download” from an Interactive Grid.  After some quick searching of the logs, I realized that APEX simply does not record this type of activity, aside from a simple page view type of “AJAX” entry.  This was not specific enough, and of course, led to the next question - can we prevent users from downloading data from a grid entirely? I knew that any Javascript-based solution would fall short of their security requirements, since it is trivial to reconstruct the URL pattern required to initiate a download, even if the Javascript had removed the option from the menu.  Thus, I had to consider a PL/SQL-based approach - one that could not be bypassed by a malicious end user. To solve this problem, I turned to APEX’s Initialization PL/SQL Code parameter.  Any PL/SQL code entered in this region will be executed before any other APEX-related process.  Thus, it is literally the first place that a developer can interact with an APEX p
