Is it unique?

Some things to share…

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,

Tech14-Ive_SubmittedI 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...)

PL/SQL vs SQL

plsql_logoThere 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:

Oracle PL/SQL Programming 6th edition by Steven Feuerstein

opp6_catI 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...)

Typical

After a presentation by Lucas Jellema I decided to try something with types in Oracletable_EMP. 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.

So I tried something like this:

type_EMP_T

KScope14

ODTUG_Kscope14

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:

APEX 5.0 Early Adopter

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 ApplicationBuilder  ApplicationBuilder, but I think the biggest visible change is (more...)

Creating hidden paths in Powerpoint

When you are, like me, creating presentations you might want to have the possibility to hide certain slides and only show them when time permits. You can of course just skip over the slides during your presentation, but that is not a good practice IMHO. It is better to add (more...)

Favorites

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.
