Behind the scenes of an all APEX organized conference

Recently we held the very first edition of the “APEX Alpe Adria” conference in Graz, Austria (see this old post about how it started). This conference is meant for everyone in the Adriatic Region, and everyone willing to travel there.

With more than 180 attendees it was a huge success for the first edition. Today I want to share how we managed the conference, website, call for papers, selection, name tags, and so (more...)

The top 3 reasons to attend malagAPEX!

The explosion and adoption of Oracle APEX continues across the globe, and clear evidence of this is the introduction of not one but two new all-APEX conferences.  At the end of May 2018 is the latest APEX conference, malagAPEX.  If you're looking for an opportunity to get connected with the growing APEX community, this is an excellent place to start.

Here are the top 3 reasons why you should consider attending malagAPEX:

  1. The (more...)

And these motivated youngsters bring 24 more youngsters far away from the Oracle APEX universe.

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 (more...)

Why you should sponsor an event

I love to go to Oracle meetings, conferences, trainings, and all that. Why? I actually like my job and I want to get better at it. Also I’m very lazy and always look for shortcuts and easier ways to do things.

Going to an Oracle (APEX) event is always very valuable for me (you can substitute Oracle or APEX for whatever field you are working in, but mine is #orclapex and I’m grateful I ended (more...)

APEX 18.1 New Feature: Logging Web Service Requests

APEX has turned 18 (ish) and EA-2 is now available. In this post, I will introduce a brand new (very small) feature of APEX 18.1.

APEX has had some support for consuming web services even before it was a shipped product (even before it was called HTMLDB). With this release of APEX, Carsten Czarski has made consuming RESTful style web services and the new ORDS REST Enabled SQL feature a breeze. You can read (more...)

My top 3 to gather user feedback in an Oracle APEX app

In every Oracle APEX application we create, we add a feedback mechanism. We're not only doing this during the development phase, but we also leave it enabled in production.

We want to give the users the ability to give feedback to the team in a structured way. It should not be an hassle to give feedback, one click for the user where he can say what it's going; if he likes (more...)

CREATE or COPY master data pages in APEX

In this blog post I just want to give a hint about the positive and negatives effects when you COPY master data pages for different master data tables.

Both tables have the same columns :

In APEX you have a Master - Detail view including 2 pages: report view and modal dialog

If you decide to copy both pages (more...)

Interactive Report – Column background color

One of my customers needed an IR where half of the report columns should be visualized in another color.

It is really easy to integrate. Go into the report column attributes inside your "Page Designer" and add a "Static ID" for each column:

Column 1: rep_col_diffcolor_1
Column 2: rep_col_diffcolor_2

Now add this CSS snippet inside the page attributes:

.a-IRR-table tr td[headers*="rep_col_diffcolor_"]
    background-color: #99ccff;

The trick is to address every element by searching for the start part of the "Static ID" name.

APEX ist anders. Genau das gleiche gilt auch für die APEX Connect!

Es gibt zwei Dinge die ich in über 10 Jahren im Oracle Umfeld immer und immer wieder höre:

1. Die Community wird immer älter.
2. APEX ist aus Grund XY schlecht.

Was hat die APEX Connect damit zu tun?
Die APEX Connect beweist nun zum 4ten Mal, dass eine Community (wie die Technologie selbst) nicht stehenbleiben darf. Ohne die gemeinsame Arbeit an immer wieder neuen Angeboten wäre die Veranstaltung wohl nicht das was sie heute (more...)

APEX Alpe Adria – A New APEX Conference That You Should Attend

Have you heard of APEX Alpe Adria?  It's the latest "All APEX" conference, joining APEX World and APEX Connect as high-quality conferences dedicated to Oracle APEX developers and related technologies.

APEX Alpe Adria is a very modestly-priced one-day conference occurring on April 20, 2018 in Graz, Austria.  The list of speakers that they have organized is unbelievably impressive - they are all very knowledgeable & experienced, as well as very polished presenters.  (more...)

Translating User Agent Strings

For the Analyse Webserver Logfile Application (AWL) I wanted to show better information instead of just the Useragent String, because they are a mess and contain confusing information.

As an example look at this Useragent String: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.109 Safari/537.36

I rather would want to show it like this: Chrome (59) OS X

How do I Refresh a Region or Report after a Dialog is Closed?

I was going to write this blog post back in December 2017, but a colleague on the APEX Development team told me it was unnecessary (because numerous examples are available in the Sample Database Application and other sample applications, and it's even in the documentation).  Well, I received this question from an internal employee today:
"When I edit the page and update the row and save and close the modal page, existing report (more...)

apex_application.g_f0x array processing in Oracle 12

If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one:
then you disable the "Escape special characters" property and the result is an updatable multirecord form.
That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. (more...)

APEX World 2018: Het gaat los!

While we're delighted that there are more APEX-focused conferences springing up around the globe, there is one conference that started this trend, and that is...APEX World.  Thanks to the foresight of the Dutch Oracle User GroupRobin Buitenhuis and Oracle ACE Learco Brizzi, APEX World was started 9 years ago, with the primary purpose of bringing together the growing APEX community in the Netherlands.  Since that time, it has (more...)

Streaming flat File data into Database

For my little Webserver Logfile Analysis project I had to solve the problem of how to stream data from a flat file into a relational datamodel in my target database.

Since I used NodeJS in several projects over the past years, it came to my mind at first. On a second thought and by consulting some friends another, easier, solution materialized:

A simple shell command.

Our Webservers run some Linux, so a tail -f is (more...)

Webserver Logfile Analysis with Oracle APEX

Recently I wanted to set up better monitoring for our several FOEX webservers and decided not to use an off-the-shelf solution, since I wanted to have the analysis results in my Oracle Database, ready to be used by whatever internal tools we have.

Immediately I thought of an old blogpost by Carsten Czarski (him and Tim Hall seem to have all Oracle answers present on their respective blogs), but decided against using remote tables spread (more...)

Authenticate APEX via Token

This requirement pops up every now and then, time to put it in a blogpost so I can find it myself again when needed :-)

In various integration scenarios it is required to have users swiftly move between applications written in various technologies. This is very common for legacy Forms applications where some functionality is moved to APEX. From the Forms menu one entry could open a Form, another one an APEX page.

But this (more...)

Who used in 2017?

A number of years ago, I provided statistics on the geographic distribution of people who used the free, evaluation service for Oracle Application Express at  I did this in 2008, 2009 and 2011.  It's time for an update. 

I've included a graphic of the top 30 and the full report below, and here are my observations:

ORDS got a new love for trailing slashes

We recently upgraded a Web server from Oracle REST Data Services 2.10 to the latest version 17.4.1 . This might sound like jumping from the stone age to spaceships, but there have been only roughly 3 years between those two versions.

The good news is, ORDS ran fantastically stable for so long, and would have continued to do so even longer, but we wanted to use the latest and greatest features, hence the (more...)
