New Link to My Demo.zip PL/SQL script files

For over a decade, PL/SQL developers have headed over to PL/SQL Obsession (on ToadWorld.com) to download my demo.zip file. They do this because all of my trainings references files from that zip by name. I use them to demonstrate  PL/SQL features, test performance of those features, and even offer some (potentially) reusable utilities.

I have, as hopefully you know, moved on to Oracle Corporation. PL/SQL Obsession will still be in place for another year or so, and it will take me some time to construct a new portal for "all things PL/SQL".

In the meantime, however, and going forward, if you want to download the very latest version of demo.zip, you can use either of these links:
http://www.oracle.com/webfolder/technetwork/tutorials/plsql/sfdemo.zip
http://goo.gl/FPG79Z
If you encounter any problems with this archive or individual files within it, please don't hesitate to drop me a note.

    and it will take me some time to construct a new portal for "all things PL/SQL".

    so, when you say portal for PL/SQL , can we expect something like asktom.oracle.com ?

    Yes and no. I do not plan to create a forum like environment in which you can ask questions and get responses, like Tom does. He does that extremely well already for SQL and PL/SQL. I will be looking to add other features, content, capabilities.

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, ...

PL/SQL 101: Three ways to get error message/stack in PL/SQL

The PL/SQL Challenge quiz for 10 September - 16 September 2016 explored the different ways you can obtain the error message / stack in PL/SQL. Note: an error stack is a sequence of multiple error messages that can occur when an exception is propagated and re-raised through several layers of nested blocks. The three ways are: SQLERRM - The original, traditional and (oddly enough) not currently recommended function to get the current error message. Not recommended because the next two options avoid a problem which you are unlikely  to run into: the error stack will be truncated at 512 bytes, and you might lose some error information. DBMS_UTILITY.FORMAT_ERROR_STACK - Returns the error message / stack, and will not truncate your string like SQLERRM will. UTL_CALL_STACK API - Added in Oracle Database 12c, the UTL_CALL_STACK package offers a comprehensive API into the execution call stack, the error stack and the error backtrace.  Note: check out this LiveSQL script if...
