How Has SQL or PL/SQL Changed Your Life?

It's not hard to identify some of the key enabling technologies of the Information and Internet Eras: Windows, Linux, HTTP, HTML and Java all come to mind.

But likely what doesn't come to mind immediately, these days, is:

SQL and PL/SQL

Seriously, how important can these be or have been when there's an entire software movement that puts the word "No" in front of SQL?

Extremely important, it turns out.

The SQL language, with its set-oriented and declarative power, revolutionized the way programmers, DB administrators and at least some end users worked with, and work with, data.

PL/SQL enabled the creation of powerful, effective mission-critical applications that run pretty much everything that modern human society relies on, day to day.

Sadly, we work in an industry that is perhaps more fashion conscious than the fashion industry. itself. We are always driven to get excited about the latest, greatest (or at least newest) thing. And when a technology's been around for 35 years how good could it really be, anymore?

Pretty darn good, when you're talking about SQL.

I get it that SQL and the relational model at least temporarily has been unable to handle the demands of Big Data and unstructured data. I get it that the world has changed a lot and there are some new requirements out there.

I get all that. What I don't get is that these new requirements cover a tiny percentage of use cases. The vast majority of applications, of user requirements related to data, are still handled best with the relational model.

Talk about throwing out the baby with the bathwater!

Well, folks, it's time to fill up the bath with sparkling spring water and put Baby SQL and Baby PL/SQL back in. [That's probably stretching the metaphor too far, but since I love babies so much, I will go with it. Don't believe me? Check out the Flickr page for my granddaughter.]

It's time, in other words, to "fight back", to recognize the incredible value and importance of the technologies with which we work, and of the work we do.

It's time, in short, to celebrate SQL and PL/SQL!

At Oracle Open World 2014, Oracle Technology Network will host the first-ever YesSQL! A celebration of SQL and PL/SQL.

No feature Powerpoints. No demos. Here's the description:

Co-hosted by Tom Kyte and Steven Feuerstein, YesSQL! celebrates SQL, PL/SQL, and the people who both make the technology and use it. At YesSQL!, special guests Andy Mendelsohn, Maria Colgan, Andrew Holdsworth, Graham Wood and others share our stories with you, and invite you to share yours with us, because?.

YesSQL! is an open mic night. Tell us how SQL and PL/SQL - and the Oracle experts who circle the globe sharing their expertise - have affected your life! 

Bottom line: If developing applications against Oracle Database is a big a part of your life, join us for a fun and uplifting evening.

I hope you can join us at the event (you'll be able to sign up for YesSQL! just like for a regular OOW session). 

But if you can't (or even if you can), you can share your story with us, right here (and on the PL/SQL Challenge, in our latest Roundtable discussion).

How has SQL and/or PL/SQL and/or Oracle Database changed your life, personally, professionally or otherwise? We will select some of your stories to read at the YesSQL! event and if you are attending, you can tell the story yourself.

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...

How to Pick the Limit for BULK COLLECT

This question rolled into my In Box today: In the case of using the LIMIT clause of BULK COLLECT, how do we decide what value to use for the limit? First I give the quick answer, then I provide support for that answer Quick Answer Start with 100. That's the default (and only) setting for cursor FOR loop optimizations. It offers a sweet spot of improved performance over row-by-row and not-too-much PGA memory consumption. Test to see if that's fast enough (likely will be for many cases). If not, try higher values until you reach the performance level you need - and you are not consuming too much PGA memory.  Don't hard-code the limit value: make it a parameter to your subprogram or a constant in a package specification. Don't put anything in the collection you don't need. [from Giulio Dottorini] Remember: each session that runs this code will use that amount of memory. Background When you use BULK COLLECT, you retrieve more than row with each fetch, ...

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...
