A comparison of sucking data into a table over a db link using DBMS_PARALLEL_EXECUTE.
This particular example is based on something I needed to do in the real world, copying data from one database into another over a db link. Datapump is not available to me. Tables in question happen to be partitioned by a date-like number (boo!) hence some of the specific actions in the detail.
I think it’s a good example of (more...)

A quick tip for keeping a single shared SQL history repository among different installations of SQLDeveloper, for the same user, on distinct computers synchronized with Dropbox.
This seems to be working just fine on Mac OS X and SQLDeveloper 4.0.2 however it's a totally unsupported
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...)
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.
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)
Introduced as an Option Oracles In-Memory option will change the world of databasing also like SAP HANA does; Since July the release is out but the search for resources and documentation is poor;

Do you have a group of employees or members that you would like to train? Would you like to make the training available for a limited time only - such as for 2 weeks? Would you like to have the ability to take the ability to view the training away at your discretion (such as when an employee leaves the company)? Would you like to know who watched which videos? For example, did Jim watch (more...)
One annoying thing from installing Oracle Database 11g on Fedora, was that the up arrows for command history didn’t work. I decided to fix that today after seeing Lutz Hartmann’s article on
rlwrap. Unfortunately, the
epel (Extra Packages for Enterprise Linux) package he recommended doesn’t run on Fedora 20. You can read my tale of woe, or skip to the
.bashrc function that fixed it when I installed only

Sorry for staying quiet for some time, but for some good reasons. Some of these reasons will be explained in later posts, but for now I would like to share the story I wrote upon request of Steven Feuerstein
, who asked to tell how PL/SQL impacted our life. Here is my story:
I started to work with databases already in college, but more from the data modelling/business analysis angle. When I moved to (more...)
Funding Makes a Huge Difference
Once we closed on our series A funding in May, we were able to afford some of the top industry talent to take InteliVideo to the next level. It's been a very exciting couple of months and it promises to be a very exciting next several years from the looks of it.
SO Many Great Uses
As we've been working with our customers, we continue to see so many impressive (more...)

Once again the ADF PMs have been hard at work to provide us all with great training content. This time in the form of a full online course.
Oracle University has begun the First Global Teach of the Oracle Middleware 12c: Build Rich Client Applications with ADF course online.
This course covers all the useful features of ADF Business Components including how to build and test reusable business services. After creating the application they drill (more...)
A recent addition to my Oracle PL/SQL library is the book Oracle PL/SQL Performance Tuning Tips & Techniques by Michael Rosenblum and Dr. Paul Dorsey.
I agree with Steven Feuerstein’s review that “if you write PL/SQL or are responsible for tuning the PL/SQL code written by someone else, this book will give you a broader, deeper set of tools with which to achieve PL/SQL success”.
In the foreword of the book, Bryn Llewellyn writes:
Gartner has just released another iteration of their classic “Hype Cycles.” They are up to more than 100 different topics now, but one interesting graph is one is the one for Emerging Technologies.

I want to comment on a couple of points from this graph:
- Internet of Things as peaking – completely agree. Everybody is talking about it but what do we have? An internet-connected smoke alarm.
- Big (more...)
I’m not in favour of calling books a “must-read”, but if you want to get your own book commercially published, I have to say you must read Write the Perfect Book Proposal: 10 That Sold and Why, 2nd Edition.
The main force of this book is that it explains the publishing industry from the inside: What a publisher is looking for. The authors honestly explain what the publisher will and will not do, and that (more...)
I’ll be going to the UKOUG Tech 14 conference in Liverpool in December to give one of my favorite presentations: “APEX or ADF? From Requirements to Tool Choice”. I’m also leading the Development Tools roundtable, which is always lively at the UKOUG conference. If you want to discuss your options as a developer in the Oracle world, UKOUG Tech 14 is the place to be.
APEX or ADF? From Requirements to Tool Choice
You want a checkbox item on a page which is a preference, you want it to be remembered for the user across login sessions, but you don’t want the overhead of storing it in a database table. You might choose to store the value in a cookie instead. It may be lost (e.g. when the user clears their cookies or changes to a different browser or another computer), but we don’t mind – it’s just a preference.
