Compact set of general PL/SQL conventions.

Written on April 19th, 2016 by Nielsno shouts

What would you tell a junior developer about PL/SQL best practises if you only had 60 seconds? Not that easy, right? I will give it a try by creating a Top 5 list:

1. Solve your problem in this order: SQL first, then PL/SQL, then Java, then C.
2. Avoid context switches between SQL and PL/SQL
3. Use bind variables in SQL
4. Use bulk operations
5. Avoid triggers

More info here: https://github.com/Doag/DOAG-PL-SQL-Coding-Conventions/blob/master/articles/00_general.md

Do you also have best practises around PL/SQL development? Now is your time to share it with us! We, the DOAG community, are trying to get 10-20 pages in place on GitHub that will give you a general basic overview of all that matters most around best practises for PL/SQL development.


We are also working on something similar around APEX, so if you are into APEX, please contribute here:


Let’s wreck this together!

DOAG e.V. is a society focused on sharing experiences around Oracle products. They also organize big events like the annual DOAG conference, JavaLand or APEX Connect. Being an active member and representative, I get the chance to bring ideas of the DOAG community into reality. Amongst many initiatives from the group of people that represents the development community within DOAG e.V., I would like to point out one that is beneficial to the whole Oracle community, but rarely known. In 2015, it was decided to make ALL content of DOAG freely available for download. No registration hassle, no fee, but literally thousands of presentations of all DOAG events waiting to be consumed by you!

Here is the link to start exploring this treasure:


So, for instance, if you are looking for all development presentations during DOAG Conference 2015, navigate to /pub/docs/Konferenz/2015/vortraege/Development.

Have fun with it!


APEX Connect 2016.

Written on März 14th, 2016 by Niels2 shouts

This year, the 3 day conference APEX Connect will be THE conference for database centric developers. If you haven’t signed up yet, please do so, as the early bird entrance fee will end tomorrow!

So what do you get for your time and money? Well, we have 60 presentations about PL/SQL, APEX, JavaScript, CSS and Oracle Database features/tools. We have keynotes from Chris Saxon (the 2. Tom Kyte?) and Mike Hichwa (VP at Oracle & the Godfather of APEX). We have well known presenters from all over the world. We have 7 hands-on workshops. We have a lunch & learn session. We have loads of networking being done throughout the day and we will end the second day with a huge party! We have booked the coolest hotel in town. Last but not least: it is all happening in the middle of Berlin, a city you just have to see for yourself.

So, act, now, otherwise you might regret it. Don’t say I didn’t warn you. :)

APEX connect 2016: save the (changed) date!

Written on September 14th, 2015 by Nielsno shouts

Today, a new website for APEX connect 2016 was launched: apex.doag.org. Through this website, you can now submit your abstracts, so don’t hesitate to do so!

Did you notice the date: 26-28 April 2016? Well, it has changed. The reason behind this, is that we wanted to offer a high quality environment that is definitely non-standard. Although we planned a different date at first, we had to reschedule things to make an experience possible you have never witnessed at a conference before. I will go into more details at the DOAG conference this year, but rest assured: TOGETHER WE WILL ROCK THIS CONFERENCE!
