Leisure Suit Larry Ellison

Larry Ellison 1978
So at 70 years of age, the man who's been heading Oracle since before I was born is stepping down.

While I admit I'm far removed from the reality of the situation, I find it a little amusing how it's been deemed as a 'shake up' when a few paragraphs before he's quoted as saying this (referring to new co-CEOs)
“I am going to continue to do what I have been doing (more...)

Using Post-Authentication to run process after APEX login

A frequent requirement, and hence frequent question on the forums is
How do I run procedure x after the user has logged in?
This is often required for such tasks as determining user access, such as populating a restricted Application Item relating to a role like F_IS_ADMIN based on the username defined in substitition string APP_USER

Those new to APEX and unfamiliar with certain concepts may consider using an Application Computation, firing "On New Instance (more...)

Birds don’t make the best ornithologists

This week I listened to episode 44 of one of my favourite podcasts - Inquiring Minds. It was an interview with David Epstein on the 'science of athletes'.

The podcast culminated with some really interesting points regarding the concept of 'talent' - what it really means, how it can be measured or influenced. One particularly interesting basis was the traditional idea that '10000 hours' training leads excellence in any particular skill, vs what's in the (more...)

OTech Magazine Issue 4 – APEX 5 and much more

Well it's the second half of August and this is my first real post for the month. There are two very good reasons for this:

1) We've just completed a major implementation at one of our clients - a tablet based application using APEX, which completely changes the face of a major arm of the business. It's a groundbreaking application with only one peer in the industry - which users are already claiming superiority to (more...)

Demystifying Oracle Unpivot

A couple of years ago I posted a simple example using PIVOT, converting rows to columns with the classic example of figures by months.

Oracle 11g R1 also introduced the UNPIVOT function, allowing columns to be converted into rows.

Problem

I've created an example that lists cities by row, but two attractions as two columns, with pairing attributes describing the reason for the attraction.
create table aus_attractions(id  number, city varchar2(50)
, attraction1 varchar2(50)
, (more...)

Case sensitivities and making JavaScript more like PL/SQL

Yesterday the Anti-Kyte (a.k.a. Mike) published a great post on coding styles. I started to post a comment but ended up rambling to I thought I'd put my thoughts here.

I can't be one to comment on tangential intros (just look at any of my presentations), but he almost lost me when I thought the entire post was going to be soccer jokes I didn't get but switched in time to three controversial (more...)

APEX Printer Friendliness using CSS Media Queries

In the projects I've been involved with I've rarely seen it used, but there is a ninth argument in the f?p= syntax that toggles Printer Friendly mode.

Side note - being the space geek I am this reminded me of the hubhub over Pluto being the ninth planet.

The APEX documentation on Printer Friendly mode states
When referenced, the Application Express engine does not display tabs or navigation bars, and all items are displayed (more...)

Order APEX column based on hidden data

An occasional question in the forums relates to issues ordering a particular column. It's one of those things that will probably keep coming up, so it's worth having another reference out here on the web.

The basic example stems from the need to order data that might contain characters.

with data as
(select '1' vc from dual union all
select '11' vc from dual union all
select '2' vc from dual union all
select 'a' (more...)

Returning BLOB file size

Occasionally I'll want some form of report noting file sizes of blobs in a database.

The solution is relatively simple, and I thought I'd write it up here for a place to copy syntax each time.

APEX users also have a handy table to verify this against (apex_application_files). Well, a synonym/view that ultimately maps to the core table wwv_flow_file_objects$.

It contains a doc_size column, which is no doubt evaluated at some point during upload of (more...)

Thursday Thought – History & Creativity

My sister sent me this video not long after my daughter was born earlier this year - I finally watched it while cleaning up e-mails and I'm glad I did - I highly recommend you all take 2 minutes aside and just let these images of history wash through your brain.



If you think the first half had an air of familiarity, you might be thinking of this video from Carl Sagan - I certainly (more...)

Two milestones, one offer

I stumbled across a blogging milestone while fact checking what I was going to open this post with - for me this month represents 5 years of blogging.

In that time I've learnt heaps, met new people, changed blog name, visited other cities to speak, and dived deep into APEX after a long time in Oracle Forms, published a video series & was recognised as an Oracle ACE.

Turns out Packt Publishing are celebrating (more...)

For those not at Kscope14

Geographical, monetary or otherwise - some of us simply can't make it to the conference every Oracle developer should do at least once, or so I've heard.

For those of us stuck at home we do have some options.

1) ODTUG offers a LiveStream of selected presentations. 

I stayed up past my bedtime to watch Patrick Wolf introduce the APEX 5.0 Page Designer. I look forward to watching the recording of Shakeeb Rahman (more...)

Oracle APEX 5 EA2 ready for consumption

After last night's teaser I thought I'd try apexea.oracle.com again to see if EA2 was ready, and it is!

and it looks darn sexy

Confirmed in Twitter by some big-wig APEX dude at Oracle
I've had bit of a play and it it's very impressive - plenty (more...)

APEX 5 EA 2 is almost upon us

KScope14 is just days away from kicking off and hours after I realised the live stream of Patrick Wolf's APEX 5.0 Page Designer presentation was actually at a reasonable Perth hour (9:30pm), I found out I wasn't going to be home to watch it - darn it!

Luckily in this age of the internet there are other reasons to get excited. Tonight while I continued to write my Prezi on how APEX 5 will (more...)

SQL Analytics – Ranking with ordinal suffix

SQL Analytics provides a fairly simple mechanism for determining positional rank within a set of results.

Before I demonstrate that query - which is already found in many good libraries - I thought I'd show how we could take it a step further and add the ordinal suffix (st, nd, rd, th) to a result.

We can do this using date format masks

with placing as (select rownum rn from dual connect by level <  (more...)

SQL Analytics 101 – Break columns

SQL analytics can be used to generate break columns in your queries, without the need for break formatting attributes in APEX or the old fashioned break on option in SQL*Plus.

I came across an example recently where I wanted to apply the break formatting in my query to avoid extra sub-totals from being displayed after each break.
No sub-totals please
I could use jQuery to hide the rows instead of modifying them, but as (more...)

Enhancing APEX "no data found" message

Truth be told, the default "no data found" message for APEX reports is pretty boring.

Out of the box

Even the default wording irritates me just a little bit every time I see one amidst a page I thought was looking pretty snazzy.


There are two things I've done recently to make it look a little better.

1) Surround it with a nice soft coloured box.

Something with a little pop

This is pretty simple, (more...)

Applying the APEX 4.3.2 patch

My experience patching Oracle APEX v4.2.1 to 4.2.3 on my Windows 7 laptop.

Background

Personally my main driver for this is to experience the updated themes and templates. I'd also like to explore the packaged applications and see if any of the dynamic PL/SQL regions have been converted to templates.

I already had 4.2.1 installed and before the patch was available to me I thought I'd try running scripts (more...)

Millions of big androids

This latest analysis on the population of mobile device technology got me thinking more about the typical sized screen you might encounter as a global web developer.
So it's looking at 2014 Quarter 1 shipment of nearly 280 million smartphones. 81% are now android, only 16% related to Apple - that next iPhone better be (more...)

APEX 4.2 Application builder icon size

A common bug-bear for me is the large distance on web pages between the browser toolbar and the start of any real content on the page.

I remember providing feedback during a tryapexnow beta release on the issue

Gimme content without scrolling!
I can't expect too much - while news websites are frequent offenders for this, newpapers have also been doing it for years.
