Next ORCLAPEX-BE Meetup – Feb 2nd

Roeland organised a new APEX Meetup in Belgium on February 2nd.


This time no specific topic, everybody can get on stage for maximum 5 minutes to show something they did or to ask some feedback or help on a specific problem.

If Belgium is to far, no worries, there're meetups planned all over the world.

The next meeting in the Netherlands is on February 18th organised by Alex, Christian and Roel.

But as I said, (more...)

Setting up your own local Oracle Development environment in less than 15 minutes

The fastest and easiest way to setup your own local Oracle Development environment is by using the "Oracle Technology Network Developer Day" Database Virtual Box Appliance.

Generate nested JSON from SQL with ORDS and APEX 5

When creating web applications, at some point you will need to interact with JSON. Either you consume JSON or you need to generate it to be able to use that cool widget you found.

A few years ago when I wrote about interacting and customising charts, XML was the data format. Today JSON is more common to use as it works so well with JavaScript. I needed to pass some nested JSON - here's an (more...)

Understanding the APEX url – passing variables to items and (interactive) reports

Did you know you can recognise an Oracle APEX application through the url?

Here's the syntax:

f?p=appid:pageid:session:request:debug:clearcache:params:paramvalues:printerfriendly&p_trace=YES&cs=...

Let me give some examples:

The first part: https://www.apexrnd.be/ords/ depends on your configuration. I'm using https, my domain name is apexrnd.be and I'm using the Oracle REST Data Services as connection to the database. This is a configuration in your webserver.

The next part is f?p= f is a (more...)

Master Detail – Detail in APEX with FOEX

In the previous post I talked about Master-Detail and that it wasn't that easy to do Master-Detail-Detail today declaratively in APEX 4.2 (and 5.0).

Below is a screenshot of FOEX (a framework build on top of APEX) and a Master-Detail-Detail in there.

You can see the live example at https://www.apexrnd.be/ords/f?p=FOEX_FDOCS:MASTER_DETAIL_DETAIL:0::NO:::

Here's a screenshot of the page behind the scenes:


At first it might seem complex, but it isn't. In FOEX (more...)

Master Detail (-Detail) in APEX

In the last posts we used following tables to show (Report) and edit (Form) the data:

Another way to work with this data is using a Master-Detail report/form.
In the master we have our customer info and in the detail the products he's interested in.

Oracle APEX provides a wizard to create a Master-Detail Form
You just follow the wizard to set it up:


By default the wizard will only show related tables, which is (more...)
