Expert Oracle Application Express, 2nd Edition, is out now !

It took a while, but last month the second edition of the Expert Oracle Application Express was released. It is the natural successor of the first edition (duh), but its not just that. Some of chapters are updated for APEX 5, but about half of the chapters are completely new! And that means also half of the authors are new as well. Because this is a joint project, 14 authors, 14 chapters, one goal. And (more...)

APEX 5.0 UI Training – Looking back and towards the future

This week Dimitri Gielis and I ran a training day about all the new APEX 5.0 UI features. We had a full room with 20 enthusiastic attendees from 4 different countries. We covered some general APEX 5 UI features, the Universal Theme, Responsive Grid layouts, Template Options, Theme Roller, Theme Styles and bringing it all together using some advanced features. See the website for more details.
And - as it was the first time (more...)

APEX ReadOnly Pages – The easy way

If your Oracle APEX Application requires different types of access - full access or readonly - for different types of users, you can specify a Read Only Condition on Page level (or Region, Item, Button, etc.). 
You can set an Authorization Scheme on Application level, so it'll be applied to all pages. So if you have an Authorization Scheme named 'User Can Access Page' defined by a PL/SQL function like this:

return apex_authorization. (more...)

Announcement: APEX 5.0 UI Training – May 12th


APEX 5.0 will be released between now and the end of May. People who have already spent some time on the Early Adopter versions know this version is packed with new features aimed to make APEX developers even more productive, like the Page Designer.
Another striking new subset of features is aimed at creating better looking user interfaces for your APEX applications in an easy and maintainable way.

Riga Dev Day 2015

While waiting at the airport for my plane back to Amsterdam, I have some time to write down my experiences of the last few days in Riga.
After arriving in the hotel, I walked to the old part of town and strolled around. The old part looks very medieval (it is - so no surprises there) with cobblestone streets, old houses and very few cars. Nice!
Then back to hotel, in time for the "official" (more...)

Can you build business critical applications with APEX?

Now and then this question pops up. And today this question was delivered to my mailbox again. A customer is busy starting a project to replace a current Oracle Forms application. So he asked Oracle and one of the Oracle partners: What should we use, APEX or ADF? A valid question that has been asked - and will be asked - by numerous customers. 
Of course, there is only one correct answer and that (more...)

UKOUG 2014 – A special edition

Although I’ve attended the UKOUG conferences since 2008, this year’s edition was somewhat special to me. Based on the attendee reviews of last year’s UKOUG, I was elected as “Best Overseas Speaker”. And for me that’s quite an honour and of course a recognition for years of work - and practice ;-)
And with a title comes a plaque - it’ll get a special place on my bookshelf. 

I didn’t just get (more...)

I am running for the ODTUG Board of Directors

After some thought, I decided I will be running for the ODTUG Board of Directors this year. I have been attending Kscope since 2008 (New Orleans). Presented at Kscope and APEXPosed since 2009. Did a few webinars. Was a member of the APEX Content Team for Kscope12 and 13. And now I am the Content Lead for the APEX track for KScope14 and Kscope15. So I like spending my free time for ODTUG, to keep (more...)

What happened at the first ORCLAPEX-NL Meetup?

Yesterday the first ORCLAPEX-NL Meetup was held. Finally. We seemed to be a little behind other locations - but pretty sure we'll catch up quickly!

After (a lot of) great pizza - kindly sponsored by smart4apex - and a round of introduction of every attendee, Richard kicked off the meeting by explaining the concept of these kinds of meetups. He also gave a nice review of his first experience of Kscope during Kscope14.
The weather (more...)

What happened at the first ORCLAPEX-BE Meetup?

Yesterday I attended the first ORCLAPEX-BE Meetup. Very well organised by Dimitri and Roeland. Remarkable fact: I was not the only "foreigner" as around 30 - 40% of the - around 16 - attendees where Dutch! So Meetups can even easily cross borders ...




So after some initial socialising.... 
... ... Roeland explained the concept of these kind of meetups.






In the next hour Dimitri went over all the great new features of APEX5, like Page Designer, (more...)

Your Kscope15 abstract is due today (or before Oct 15)!

It is still a long time before Kscope15. But if I look at the website .... I can hardly wait! 
A good conference needs a good time for preparation. An awesome conference .... needs even more time. So that's why we need your abstracts a.s.a.p. After the close every member of the review committee will go over every abstract and will give it a rating and a comment. When that's all done, the (more...)

First ORCLAPEX-NL Meetup !

Earlier this year Dan McGhan - inspired by local JavaScript meetups - started the first Oracle APEX Meetup. Since then it has gone viral. As you can see on ApexMeetups the meetups are more or less global nowadays!
And even in The Netherlands we will officially join this virtual group and have our first ORCLAPEX Meetup on Thursday September 18. The location is central and well known: The Dutch Oracle HQ alongside the A2 highway. (more...)

10 New APEX 5 Features

The last two weeks I wrote a daily blogpost about a new feature in APEX 5. And intentionally I didn't cover the "big" features, like the new Page Designer, the Modal Pages, the Universal Theme etc as these probably are - or will be - covered by other people. So in my 10 blogposts I covered "Ten Tiny Things" ... 
For those who missed it - all or parts of it - herewith (more...)

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific (more...)

APEX 5 New Package Features

To get a proper list of the new packages and API's APEX 5 provides us, we have to wait for the documentation of course. But if you're impatient and want to now more, you can get a list of all package procedures and functions by running this SQL on the APEX 5 Early Adopter instance:


select distinct s.synonym_name, p.procedure_name
from all_procedures p join all_synonyms s on p.object_name = s.table_name
where p. (more...)

APEX 5 New Authorization Evaluation Point Features

In APEX 4 you can define Authorization Schemes. This is a very useful feature to prevent code repetition all over the place. For instance and Authorization Scheme "Is Admin" might use a select on one or more tables (or web service calls or whatever is necessary) to determine whether a user, the :APP_USER, has an Admin role or not. And you can use any value in session state, like :APP_ID or :APP_PAGE_ID in your query (more...)

APEX 5 New Substitution Syntax Features


You've probably all heard about XSS, a.k.a. Cross Site Scripting. One of the ways you make yourself vulnerable to XSS is by creating JavaScript in your APEX applications that accepts unescaped user input - either direct or data retrieved from the database.
As a - very stupid and simple - example, create a Page with a Text Item (say P3_TEXT).  Next create a Dynamic Action that executes this snippet of Javascript on Page (more...)

APEX 5 New Runtime API Lockdown Features

In APEX 4.x the developer could implement a feature that involves a call to the APEX API. E.g. you could create new pages on the fly if you would like to (just examine an export file for the how-to). You could drop an application using a procedure from the APEX_INSTANCE_ADMIN package. You could drop a user using APEX_UTIL.REMOVE_USER. If this is all on purpose and secured than that's fine. But maybe you (more...)

APEX 5 New Password Reset Features

Now and then it happens when we're logging in into our APEX instance: We have to change our password again .... And that means, typing it in an awful number of times:
1. Current Password
2. New Password (and of course preferably the same as the current one ...)
3. Confirm New Password
4. Press Apply Changes
5. Press Retun
6. And we're back at Square One : The login screen - and here we type (more...)
