I love the Apex UI, it makes development so much easier and more convenient – and makes it easy to impress clients when I can quickly fix issues right there and then, using nothing but their computer and their browser, no additional software tools needed.
However, at my main client (more...)
I was looking at the Apex 4.2.2 installation script (coreins.sql), and noticed the mention of a new package, wwv_flow_json, which is apparently being worked on but was removed at the last minute "as no longer required for 4.2.2".
Even though the package is not installed (more...)
The Thoth Gateway
is a gateway written in C# and ASP.NET that allows you to run PL/SQL web applications (including Oracle Application Express) on Microsoft's Internet Information Server (IIS). You can read more about the gateway here
. It is an alternative to Apache/mod_plsql and the Java-based Apex Listener.
This isn't really an easter egg
, just more of a mild bug that makes you think - hopefully a little more about your own applications.
If you type in "0" in the page navigation bar, it takes you to the typical global page / page zero for desktop.
Oracle Application Express for Mobile Web Applications
If you haven't heard about this book yet, you're not reading enough media on-line.
APEX regulars Roel Hartman
, Christian Rokitta
and APEX product manager David Peake
are the published authors, but I think it’s safe to say we can also thank Dan McGhan (more...)
I have used APEX 4.2.2. I was unable to logon my APEX with INTERNAL workspace as admin. It showed "The account is locked
What was I able to do? ... run "apxchpwd.sql" script. I didn't think so. After checking in "apxchpwd.sql" script.
So, I checked (more...)
iAdvise organises a free seminar about Mobile Business Development on 4(Antwerp, Belgium) and 6(Breda, The Netherlands) June.
In this seminar we will discuss Mobile Development and Usability(UX – User Experience) in Mobile Development.
But we also compare different solutions, give pros and cons about: APEX Mobile, ADF Mobile and Tabris.
Here is a short story about a little problem that caused me a bit of grief; but in the end had a simple cause and a simple fix.
I had a dynamic action in my Apex 4.1 app that had to run some PL/SQL – which was working fine, (more...)
The Oracle APEX Listener is a Java based alternative to using Oracle HTTP Server (OHS) with mod_plsql. In the past I’ve installed early versions of APEX 3 using this configuration, then later on started using EPG (Embedded PL/SQL Gateway) which worked fairly well. Recently however, I decided to try using the latest APEX (more...)
A standard Oracle 22.214.171.124 database installation comes bundled with Application Express (APEX) 3.2.1 by default. I’m going to upgrade to the latest version of APEX (currently 4.2.2) and then configure the Embedded PL/SQL Gateway (EPG), which uses the Oracle XML DB HTTP components within the database (more...)
Those crazy kids at ODTUG have done it again! At this year’s KScope in New Orleans this user group is introducing an evening of crossover sessions. Over the years the event has grown and actually blended the traditional Oracle database development world with the world of EPM, Hyperion, and Essbase. (more...)
Hide/Show regions are very useful in that they allow users to hide certain on-screen content when it’s not relevant for them (and show it again just as easily) simply by clicking the small arrow icon in the top left of the region.
But how can you programmatically do the (more...)
APEX is well known for his RAD solution and the no-extra cost factor: APEX makes it possible to build on time and within budget your database application for the web. But an application is more then building pages for CRUD operations. Very often you also need to generate well looking (more...)
April 9th 2013, APEX World took place, one of the biggest APEX only events in the world, organized by the Dutch Oracle user group (OGH). iAdvise was gold partner of this year’s edition. Below is a view on this event from our perspective.
The event (more...)
When creating LOVs for APEX I sometimes debate to myself whether to make a static or dynamic LOV.
I had one scenario where having some SQL was handy, so I started with this
SELECT TO_CHAR(NEXT_DAY(sysdate, 'MON')+ROWNUM-1,'DY')
CONNECT BY LEVEL <= 7;
It's possible to then place this as (more...)
When working with APEX, you also need a number of tools to improve the efficiency of your work. It isn’t enough to just have the APEX IDE at your disposal. Besides the APEX IDE for the application development, you may use a bunch of other tools. This is what I (more...)
It’s been quite some time since my last post. It’s not that I haven’t been busy, just didn’t find the time or a subject to write a blog about. Until now.
I came up with something I didn’t know. I have a pipelined table function where I want to suppress a record from appearing when something is wrong (no data found or something like that). I know, suppressing errors is wrong, but in this case I will log the error. I just didn’t want it to appear in my data because the receiving application will generate errors and reject the (more...)
I has been quite some time since I posted anything on my blog. That is mainly because I am busy with other things at the moment:
I will be presenting at the OGh Apex Event in Zeist (the Netherlands). I will be doing a presentation on how to build a plug-in for Apex, together with Alex Nuijten.
AMIS will be sponsoring the SQL Challenge in April. I have made a couple of questions for that. Lucas Jellema also made a couple of questions and we are now in the process of reviewing and approving them.
I will be doing (more...)
In this post I’ll finish up the CRUD implementation using records, procedures and views. This series of blog posts started with this post which was followed by this.
At this point we have a working report that links to a form. The report is based on a view and the form is based on a procedure. At this point the form is only loading the record in using a procedure that uses a record in its signature. In this post we’ll complete the functionality by using the same form for insert, update, and delete functionality.
Let’s start with adding a (more...)
Like a middle aged man visiting the gym for the first time in 10 years, I am merely going to flex my blogging muscles here…
One of the recurring issues that annoys me on the OTN SQL & PL/SQL forum, and also the APEX forum is the misunderstanding of what (more...)
