1. Infoprenuers - these are companies who do something and have video, but video is not their primary business. For example, RunBare. Their primary business is teaching people how to run in your barefeet. They do have a video on this topic, along with books and other items. Another example is BDB Software, which is my (more...)
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...)

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...)
Oracle 11g R1 also introduced the UNPIVOT function, allowing columns to be converted into rows.
ProblemI've created an example that lists cities by row, but two attractions as two columns, with pairing attributes describing the reason for the attraction.

, 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;

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

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’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...)
