When you migrate to APEX 5.0 and the Universal Theme you might see that some plugins are not behaving correctly anymore. In this post I'll discuss the Enkitec Modal LOV
When I ran the plugin in my APEX 5.0 app with the Universal Theme it looked like this:
There's too much space in the search bar and the close button is not showing up with an icon.
Here're the steps I did (more...)
On Monday Bob Rhubart did a video call with me in his series of 2MTT
(2 Minute Tech Tip) on YouTube. You find my 2MMT here
I talked about using JSON and APEX and gave two examples were we use it.
In previous blog posts I gave more details on those techniques. Here's a quick overview:
comes with a new calendar region, which is way nicer than the previous calendar in APEX. It has more features, looks better and is also responsive. Behind the scenes you'll see the calendar region is based on Full Calendar
In Belgium we use Monday as first day of the week, whereas in the US they seem to use Sunday as start of the week in the calendar overview. I've been integrating Full (more...)
In previous blog posts I talked about JSON for APEX Developers:
In this post I want to show how you store and query JSON data straight in the database.
To start, create a table to store the JSON object:
CREATE TABLE ssn_json
(id NUMBER GENERATED ALWAYS AS IDENTITY NOT NULL,
After 2.5 years of development, today is the day APEX 5.0 is publicly released and ready to be downloaded
to install on your own environment.
In my view it's the best release ever. Not so much of the new Page Designer - although that is definitely a piece of art and it increased productivity even further - but because it's the first time whole of APEX got refreshed and every piece was put (more...)
Ever tried to put multiple Trees on the same page in APEX 4.2?
Here's my example:
On the left Tree the "Selected Node Link with" is set to hidden item P1_TREE1, on the right Tree the value that sets the tree is set to P1_TREE2. At least it should do that, but by default if you're values are not unique - in this case empno is the value behind both trees - it doesn't (more...)
When you create a new application in APEX 5.0, the login page probably looks like this:
I love the build-in login page of APEX itself - luckily it's easy enough to build that in our own apps too. Thank you APEX Dev team!
The first step is to change the region type to be of Login Region Template:
We want to add a nice icon on top of the Login text. You can use (more...)
I often need to load the data of Excel or CSV files into the Oracle Database.
Ever got those annoying question marks when you try to load the data? or instead of question marks you just get empty blanks when the file is using special characters? Here's an example:
My database characterset is UTF-8, so ideally you want to load your data UTF-8 encoded.
With Excel I've not found an easy way to specify the (more...)
Today Oracle released new versions of:
You may want to check Kris Rice's
blog for new features.
I already blogged about all of the tools before, but not yet about SQLcl.
This is a command line tool, I call it "SQL*Plus on steroids" (or as Jeff calls (more...)
Once you have your new application created using the Universal Theme it's time to customise your theme with Theme Roller.
Run your application and click the Theme Roller link in the APEX Developer Toolbar:
Theme Roller will open. I won't go in every section, but want to highlight the most important sections in Theme Roller in this post:
- Style: there're two styles that come with APEX 5.0: Blue and Gray. You can start (more...)
When you click on the Attributes of your Interactive Report there's a neath little new features included called "Heading - Fixed to" with as options: None, Region and Page
We've got this request from many customers and it has always been a pain to get it working in every condition with APEX 4.x, but no hacking anymore - it's there now in APEX 5.0.
When you start to scroll the column header will (more...)
In APEX 5.0 theme 42 is included - this is the Universal Theme. The theme comes with two styles: Blue and Gray.
The UI is so much improved in APEX 5, it's really a game changer. When you look at the details for example from such a style you will see it's using a Less
file (Less is a CSS pre-processor) behind the scenes. So it's very easy to make changes to the CSS. (more...)
Today Oracle released the latest Early Adopter
release of APEX 5.0.
The release is packed with new features
, but one of the biggest improvements you can find in the UI.
For me the Universal Theme with Theme Roller, Theme Styles and Template Options is the absolute killer feature of APEX 5.0. I can't better describe Universal Theme as how Oracle is describing it:Universal Theme is an all-new user interface for your (more...)
I doubted to set the title of this post to "Running APEX 4.2 and 5.0 in the same Oracle instance", but decided not to do that, but that is basically what I will do. Before going into details, I'll share my architecture.
In December 2013 I wrote
it was time to update your APEX environment and I gave a quick overview of the architecture we're using. I thought it's time to review that (more...)
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.
The definition of user interface components (more...)
In the previous post
we created a service that allowed us to give our data in JSON format.
Now let's focus on consuming that JSON. In this post I want to show how to use JSON data in the client (your browser), in a future post I'll show how to use JSON on the server (in the database).
If you want to play with JSON, open the console of your browser and create some text (more...)
After my post Generate nested JSON from SQL with ORDS and APEX 5
I got some requests to explain more about REST and JSON, so let me start with JSON. I'll go more into REST
in some future posts.
JSON stands for J
otation, it's a text based format to store and transport data.
It all comes from exchanging data, and finding a format that can easily be used (more...)
Today Oracle introduced
the node-oracledb driver, so you can easily connect from node to your Oracle database.
Previously I blogged
about the Oracle VM you can download so you have your own local Oracle environment. Below are the steps to install the node driver and run a first example in that environment.
(Also read the official node-oracledb installation guide
for a local database - 4. Installation with a local database).
First we need to install git (more...)
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...)
