Optimizing PL/SQL Panel at Oracle Open World 2015 - Questions welcome!

At Oracle Open World 2014, I was a member of a panel on SQL and PL/SQL Performance. It was an awful lot of fun, but as I had expected, most of the questions focused on SQL performance, and most of them were answered by Tom Kyte (no complaints from me!).

I came away with a strong feeling that we should offer separate panels on SQL and PL/SQL, so that each could get the proper amount of attention (or as "proper" as you can get in 45 minutes. Sigh...).

Well, my wish has come true!

There will be a panel on SQL for Functionality, Performance and Maintainability, and its future, and another on PL/SQL:
Optimizing PL/SQL for Performance and Maintainability (CON8416)
Moscone South - 306, Wednesday, October 28th, 13:45 - 14:30
Notice that we are suggesting that when it comes to "optimization," we should all be thinking about more than performance. Performance is, justifiably, a primary concern for any application developer (and DBA), but that doesn't mean it should be the sole concern.

A truly optimal application is also optimized for maintainability - the ability, namely, to fix and enhance that application over time in a way that does not consume too much of the resources of the dev team (such that it is hard to find time to build new apps, always our preference). 

We've pulled together panel that is composed mostly of expert users, not (just) Oracle employees. Sure, Bryn Llewellyn (Distinguished Product Manager, PL/SQL and EBR) will be there. And I will moderate the panel, throwing in my two cents now and then. 

But we are most excited to welcome the following "real world" expert PL/SQL developers to answer questions and share their experiences:
  • Martin Buechi,  Lead Software Architect at Avaloq Evolution AG and 2009 PL/SQL Developer of the Year
  • Kim Berg Hansen,  Senior System Developer at T.Hansen Gruppen A/S and SQL Quizmaster at the PL/SQL Challenge
  • Marcelle Kratochvil,  CTO and Co-Founder of Piction and an Oracle Database multimedia expert
So if you are attending Oracle OpenWorld and you develop applications using PL/SQL, please do join us! We will be taking questions from the audience, but if you cannot attend the session, we also encourage you to post your question as a comment on this post.

We will then answer as many as possible during the session.

Of course, you can always ask a question about SQL and PL/SQL at the OTN Community Forum, or tweet me or Bryn.

Because we all know that Twitter is the best way to discuss complex technology like Oracle Database.

Why DBMS_OUTPUT.PUT_LINE should not be in your application code

A database developer recently came across my  Bulletproof PL/SQL  presentation, which includes this slide. That first item in the list caught his attention: Never put calls to DBMS_OUTPUT.PUT_LINE in your application code. So he sent me an email asking why I would say that. Well, I suppose that is the problem with publishing slide decks. All the explanatory verbiage is missing. I suppose maybe I should do a video. :-) But in the meantime, allow me to explain. First, what does DBMS_OUTPUT.PUT_LINE do? It writes text out to a buffer, and when your current PL/SQL block terminates, the buffer is displayed on your screen. [Note: there can be more to it than that. For example, you could in your own code call DBMS_OUTPUT.GET_LINE(S) to get the contents of the buffer and do something with it, but I will keep things simple right now.] Second, if I am telling you not to use this built-in, how could text from your program be displayed on your screen? Not without a lot o...

The future of Oracle PL/SQL: some thoughts on Sten Vesterli's thoughts

Sten Vesterli published a very thought-provoking post on his blog: Please stop reading this post, and read that one. When you are done, come on back here for my thoughts on Sten's thoughts. OK. You read it. Here we go. First, thanks, Sten, for being such an interesting, wise, sometimes provocative voice in our community. Next, Sten writes: Now, on the one hand, I certainly agree that the vast majority of young developers are currently caught up in the modern version of a Gold Rush, which is: "Build an app using JavaScript, pay no attention to that database behind the curtain." But I can assure you that I still do meet young PL/SQL programmers, regularly, when I am at conferences and doing onsite presentations at companies. So, young person who writes PL/SQL: do not be afraid! You are not alone! And you are super-smart to have made the choice you did. :-) Next, Sten offers this advice to managers: I agree that PL/SQL is a "spec...

Table Functions, Part 1: Introduction and Exploration

Please do feel encouraged to read this and my other posts on table functions, but you will learn much more about table functions by taking my Get Started with PL/SQL Table Functions class at the Oracle Dev Gym. Videos, tutorials and quizzes - then print a certificate when you are done! Table functions - functions that can be called in the FROM clause of a query from inside the TABLE operator - are fascinating and incredibly helpful constructs. So I've decided to write a series of blog posts on them: how to build them, how to use them, issues you might run into. Of course, I am not the first to do so. I encourage to check out the  documentation , as well as excellent posts from Adrian Billington (search for "table functions") and Tim Hall . Adrian and Tim mostly focus on pipelined table functions, a specialized variant of table functions designed to improve performance and reduce PGA consumption. I will take a look at pipelined table functions in the latter part...
