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.

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 topics:

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.

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' vc from dual)
select vc
from data
order by vc;

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$.

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.

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.

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.

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!

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!
