Oracle Spatial (Teil 4) – Unterschiedliche Koordinaten Punkte zu einer Linie zusammenführen

Vor kurzem musste ich Daten aus einer Excel-Liste in das SDO_GEOMETRY Format bringen. Leider hatte die Excelliste einen Haken.

Die Anforderungen:
- Es musste eine Linie (Typ 2002) im GK3 Format (31467) aus VON und NACH Punkten generiert werden.
- Die Excel-Liste hatte die Punkte entweder als GK3 oder als WGS84 Format hinterlegt.

Nach Import der Daten sah meine Quelltabelle dann so aus:

Und hier das Select zur richtigen Transformation der Geo-Daten ins SDO_GEOMETRY Format:

APEX UT – Display Image in a List

If using universal theme, we can switch from a classic navigation bar to a list and display it where usually a navigation bar is displayes - right top of the page. The problem with the list is that it will escape any html code in the list name. If we want to display an image, we will get the html code. To go arround that problem, we can use the "user defined attributes" for the (more...)

APEX Master (Interactive Report) – Detail (Modal Dialog) Form: Conditional Column Link

Since APEX 5 it is much easier to create master-detail pages with modal dialogs. But there is still no declarative way to create a conditional row based column link.

This blog post will show you a way how to create a conditional row based master - detail page.

1. We need some sample data:
select 1 as ID, 'APEX Connect' as name, 1 as CONDITIONAL_COL from DUAL
union all
select 2 (more...)

APEX Modify UT Breadcrumb

While creating pages with the new UT I noticed that the breadcrumb breakes after the second level and this takes too much space.

And this is how it looks like after applying the css.

Enter your bets on now

Looks like I forgot to put on my blog also this year we created a bet site for the European Cup Soccer. Thanks to the people who reminded me to put this post on my blog :)

It all started in 2006 when I first created a site to promote Oracle Application Express (APEX). The site allowed to bet on the games of the World Cup. At that time everybody was using Excel files internally (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...)

Export your APEX Interactive Report to PDF

Interactive Reports (and Grids in 5.1) are one of the nicest features of Oracle Application Express (APEX) as it allows an end-user to look at the data the way they want, without needing a developer to change the underlying code. End-users can show or hide columns, do calculations on columns, filter etc.

Here's an example of an interactive report where highlighting, computation and aggregation is used.

More than once I get the question, how (more...)

5.1 EA

It is incredibly quiet around APEX release 5.1. Just a couple of days ago I was talking to Dietmar and we were asking ourselves when is APEX 5.1 going to be released because of our training schedule for the rest of the year. Two days ago Markus visited the EA site and this is what he found there. Many exciting things to appear in the next versions. Read the details and you will (more...)

Using dynamic tooltips in your Interactive Report

Inside an Interactive Report (IR) I had a comment column. The comments in this column could become really large and the users wanted the comments to be automatically trimmed if more then 60 characters were displayed. If the user moved the mouse above a trimmed comment then a tooltip should be display including all comment text.

My first idea was to check for existing plugins which could do this job for me. So I searched (more...)

Crowdsourced software development experiment

A few days ago I got an email about an experiment how to program with the crowd.

I didn't really heard about it before, but found it an interesting thought. In this experiment people will perform microtasks (10 minutes task), as a member of the crowd. People don't know each other, but will collaborate together. The system is distributing the work and supplies instructions. The challenge is in creating quality code that meets the specifications.

My "Must See" ADF/MAF Sessions at KScope 16

Yes, you read that right - it's not a typo, nor did one of my kids or wife gain access to my laptop.  It's part of a "blog hop" - where a number of experts made recommendations about KScope sessions that are "must attend" and are not in their core technology.  I picked ADF/MAF, as I don't have any practical experience in either technology, but they are at least similar enough that I would not (more...)

Please, use HTTPS for your APEX apps

Why use HTTPS?

When you Google this question you get many different answers, but this answer of Google Developers answers it for me in short (click the link for more details):
  • HTTPS protects the integrity of your website/APEX app
  • HTTPS protects the privacy and security of your users
  • HTTPS is the future of the web; many new technologies only work with https (for example Service Workers; you can read more about Service Workers and APEX (more...)

The APEX CONNECT and the APEX dashboard competition 2016

Before I tell you about the APEX dashboard competition winner I want to share my impressions from the APEX CONNECT 2016 in Berlin with you.

We had 3 days fully packed with APEX, SQL, PL/SQL, SQL Developer and different JavaScript technology topics.

In every way Niels de Brujin, Carsten Czarski, Christian Schwitalla and the whole DOAG team created an amazing event and has raised the quality compared to the last year.

We had more attendances, (more...)

Web technology in APEX Development

How did you get started with developing your first APEX app? 

My guess is either you went to and got a free account or Oracle Application Express was already in your company and somebody told you the url you could connect to. For me that is really the power of APEX, you just go to an url and within minutes you created your first app.

Staying within the APEX framework?
