Using inline dialogs in APEX 5

APEX 5 has built-in support for dialog boxes. These come in two varieties; dialog pages (which show another standard APEX page in a dialog box using an iframe) and inline dialogs (which show a region on the current page as a dialog box). John Snyders goes into great technical detail about APEX dialogs and the differences between the two types.

This post is a quick summary of how to use inline dialogs. As John points (more...)

Creating an APEX plugin for an Oracle JET component – Part 2

In my previous blogpost I showed how you can embed an Oracle JET component in your APEX application. Now it is time to make a plugin out of the wisdom we gained doing so.
First of all a disclaimer. My intention is to make this plugin and the inner workings as simple as possible. So you can add a lot more functionality, checks etc and therefore add complexity. But this is intended to be as (more...)

Consuming a REST Web Service returning JSON in APEX

In APEX you can define a web service that returns XML as below - all declarative, just a few steps through a wizard.


Then generate a report on top of that web service - again just a few clicks through a wizard. The generated query looks like this:

select xtab."customerName"
     , xtab."customerId"
  from apex_collections c, 
          XMLTable('/Response/S_getCustomerListTableArray/S_getCustomerListArrayItem' passing xmltype001
            COLUMNS (more...)

Prevent general row based search in an APEX Interactive Report

At my current project we use Interactive Reports heavily. But in some cases the underlying queries are rather complex and a query without any filter or with just a filter on all columns doesn't perform that well (understatement...). We already implemented a solution to prevent initial loading of the data by adding an additional criterium to the query ( :P400_SEARCH = 'Y' ). The default value of this hidden item is 'N' and on (more...)

Create a Navigation Bar based on a SQL statement

Creating a Navigation Bar using static values is very straightforward. Just create a list similar to this example below - and you can easily define multiple levels.
Then, in the User Interface Attributes, set that list to be your application's "Navigation Bar List" and specify the template.
And the Navigation Bar pops up nicely in the upper right corner of the screen.
So far so good.

But what if you don't want a Static List, (more...)

#DBADev (Ops), who knows what is going on…

I have been considering writing this article for quite some time now.
APEX Connect 2016 in Germany’s capital Berlin and the DOAG Database days have finally persuaded me to talk more about #DBADev, let me explain why…

Whenever in the stone age…

During my career as DBA, I was always working closely together with Oracle Forms & Reports developers. In retrospect, the cooperation in that time was remarkable.
These Forms & Reports developers had always (more...)

Slides and demo script from my ORDS talk at APEX Connect 2016 in Berlin

Hi everybody,

I just came back from the DOAG APEX Connect 2016 conference in Berlin ... very nice location, great content and the wonderful APEX community to hang out with ... always a pleasure. This time we felt a little bit pink ;)

As promised, you can download the slides and the demo script (as is) from my site.

Instructions are included.

See you at KScope in Chicago, #letswreckthistogether .

Cheers and enyoy!

Looking back at our flight at Apex World 2016

7 and 8 March iAdvise was present as Diamond Sponsor at Apex World. For the first time it was a two day event. Because of the success last year, the location of Apex World was again the beautiful SS Rotterdam. Over the past few years, the event became more and more international. This was clearly seen in the language of the presentations. Nearly all the presentations were held in English.

Unexpected behaviour using SSO Authentication for APEX

A customer of mine switched to a Singe Sign On Authentication Scheme for their APEX application - using Oracle Access Manager, but that's irrelevant to this case.
In the application there's a function to create an - temporarily - "real" APEX user. That APEX user is used in another JavaScript application that uses ORDS and the built-in APEX authentication - thus requiring the existence of APEX users. That function ran flawlessly when the application was (more...)

Navigating through your APEX Calendar – the easy way

The renewed Calendar Region in APEX is awesome. With just one SQL statement you can provide your users with a calendar view of their data that looks very familiar to what they already know, use and love. Apart from one thing: Navigating to a specific date is cumbersome.
The shortest route is:

  • Navigate to the right month (can be any number of clicks) 
  • Switch to "Week view" 
  • Navigate to the right week (between 0 and (more...)

Switching Interactive Report to Icon or Detail View in APEX 5 using Javascript

At yesterdays APEX Meetup in Vienna someone asked if there is a way to switch an Interactive Report programmatically (using Javascript) to Icon / List / Report – View in APEX 5, since gReport doesn’t exist anymore (which could do the job before APEX 5).

Application_BuilderAbove you see an example of an Interactive Report everyone should know: this is the Application Builder listing all pages of an application.

The task at hand is to call (more...)

APEX 5.0 Beyond basics

iAdvise presented the APEX 5.0 roadshows in the first half of 2015. Besides the presentation about the new features, we provided 3 tutorials which helped the visitors to explore Oracle Application Express 5.0. Now we offer these tutorials through our blog. In this article the second tutorial is presented.

ORA-01445 in Interactive Report when importing Apex 3.2 app into Apex 5.0

Just a quick note about an error I encountered when importing an old Apex 3.2 (!) app into Apex 5.0.2.

Using Apex 5.0.2, I have imported an application which ran fine under Apex 3.2, that had an interactive report with the following query:

select c001, c002, c003, c004, c005, c006, c007, c008, c009, c010,
  c011, c012, c013, c014, c015, c016, c017, c018, c019, c020,

Working with the Apex 5 treeview

Apex 5 includes a new treeview widget. I haven't been able to find good documentation on how to use the treeview. This blog post is an attempt to summarize what I have gleaned from the help text, forum posts, and experimentation, to make it easier for others.



Adding a treeview to a page

Let's start with the basics. The treeview is a built-in region component called "Tree". Simply drag it from the Regions palette to (more...)

My Oracle Database Developer Choice Awards 2015


Earlier this week, Santa's little helper (ie DHL) knocked on my door and delivered a package containing my trophies from the Oracle Database Developer Choice Awards 2015. I was nominated in three categories, and won awards in two of them: Application Express and ORDS.




Here's a video from the award ceremony at Oracle OpenWorld 2015:




I'd like to send a big THANK YOU to everyone who voted for me, and also to Oracle for (more...)

APEX 5.1: features shown at DOAG

On the last day of the DOAG conference, in the last time slot Patrick Wolf from the APEX development team did a session on the next release of APEX.
For the developer the most significant change in the Page Designer is the component view. This will be a tab in the center pane instead of a completely separate page.

Most time was spent showing the new Interactive Grid. The Interactive Grid will be a, loosly (more...)

How to change apex_public_user password in ORDS

When you install Oracle REST Data Services (ORDS) as the gateway for your Oracle Application Express (APEX) applications, you run the java -jar ords.war command to configure ORDS, including specifying connection strings and passwords for the service accounts apex_public_user, apex_listener and apex_rest_public_user.

The first time you run this command, you get asked where to store the configuration. A file called defaults.xml gets created in the folder you specify. It looks like this:

Apex 5 right side column

The new Universal Theme in Apex 5 includes a nice "right side column" feature that adds a sliding menu on the right side of the page, where you can place additional content, such as (for example) an audit trail, actions/links, comments, whatever.

Let me show you with a picture:


To add this to your page, simply change the page template to "Right Side Column", and note that a "Right Column" template position appears in the (more...)
