I have been awfully quiet on my blog lately. I think that is because I have been busy with other things, like my garden and stuff like that. There are some ‘techie’ thing I have done in the meantime, though,
I have submitted a couple of abstracts for Tech14. Hope at least one of them gets selected. I really like presenting and if it is in a different country, that is just a plus. That (more...)
There is a ‘rule’, I think it was created by Tom Kyte, stating: If you can do it in SQL, do it in SQL. I came across some code the other day that makes perfect sense to do then you are running an Oracle 10g (or earlier) instance. I rewrote the code to use only the EMP and DEPT tables to protect the suspects and maybe innocent.
The function defined is something like this:
I have reviewed the latest edition of Oracle PL/SQL Programming. This is not a book, at least for me, that I would read front to back. I use it mostly as a reference, but the great thing about this book is that you can also use this book to learn programming PL/SQL from scratch.
The book is nicely ordered into different parts, like Program structure and how to use SQL in PL/SQL (which by the (more...)
After a presentation by Lucas Jellema I decided to try something with types in Oracle. One of the issues posed in this presentation was that the type cannot include self-reference. Neither direct nor indirect.
A table like the emp table cannot be expressed as an object type. The table has a column mgr which is a reference to another employee.

This year, from June 22 - June 26, the best convention in the world, ODTUG’s KScope14 will be held in Seattle, Washington. I am already looking forward to meeting some ‘old’ friends again, creating new friends and seeing some of the best content by presenters from all over the world.
Some of the presentations I am looking forward to:
In the Developer’s Toolkit track:
The long awaited Early Adopter installation is finally available at http://apexea.oracle.com. You can request a workspace here to play around with the new version. I have just been playing around with it for about an hour an from what I’ve seen it’s a big change to what we’re used to since APEX 4.
Not only has the look an feel changed to flat , but I think the biggest visible change is (more...)
Last couple of weeks I have been working on an update of the Favorites plugin for PL/SQL Developer. After extensive testing by Erik van Roon, Henk Jan van Wijk and Marcel Hoefs I decided to release it. Hope you like it.
At the KScope12 conference Redgate held a live lab to develop their new tool: Redgate Source Control for Oracle. I was involved then already to help make this tool work the way developers want.
To help everyone use this tool Redgate is friendly to provide me with two (2) five (5) user licenses to their new product worth $1475 to give away.
How can you ‘win’ one of these licenses? Just write up why you really, really deserve a copy. Write up what problem will be fixed if you have source control or maybe in what nasty situation you got (more...)
