Care to join "Team Feuerstein"?

So on March 17, 2014 I joined Oracle Corporation as an Architect.

Wow, do they have lots of things for me to do!

And I want to do my very best with all of it:
  • Publish articles, presentations, white papers that are accurate, are readable, and have no mistakes.
  • Share my PL/SQL utility and sample code (and make sure they are readable and have no mistakes).
  • Find - and notify developers - about useful blogs, code and anything else relating to PL/SQL.
It is quickly becoming clear to me that I can't do it all, all by myself. And everyone else at Oracle is just as busy as me.

So I have decided to create "Team Feuerstein" - a group of Oracle technologists who share, with me, a delight for PL/SQL and SQL, and a desire to help build our community.

While you will not be paid in hard currency for your efforts, I will be very grateful and you will get public credit for your contribution.

I plan in the future to provide a webpage where you can submit an application to join the team and list your specialties. But I've decided that there is no reason to wait until that is ready.

I can get started right away soliciting your help!

So if you are interested you can do one of two things:

(a) Send an email to steven.feuerstein@oracle.com asking for more information.

(b) Send an email to steven.feuerstein@oracle.com to volunteer as a team member and provide the following information:

  • Background on your Oracle experience: free form text, LinkedIn profile, etc.
  • Your technical strengths: for example, I can definitely use help with non-trivial SQL, regular expressions, XML, etc. Core PL/SQL knowledge is, of course, great, too!
  • Other skills of interest: I plan to record lots of videos and podcasts, so if you have experience with this (esp on a Macbook), I'd love to hear about it. Excellent English writing skills? That would be very useful.
  • How you would like to be identified publicly.
Many thanks in advance for considering this!
Steven Feuerstein

  1. Well, the bit about non-trivial SQL sounds much more interesting than trivial SQL ;-)
    Can you use a dane with no Macbook experience whatsoever?

Running out of PGA memory with MULTISET ops? Watch out for DISTINCT!

A PL/SQL team inside Oracle made excellent use of nested tables and MULTISET operators in SQL, blending data in tables with procedurally-generated datasets (nested tables).  All was going well when they hit the dreaded: ORA-04030: out of process memory when trying to allocate 2032 bytes  They asked for my help.  The error occurred on this SELECT: SELECT  *    FROM header_tab trx    WHERE (generated_ntab1 SUBMULTISET OF trx.column_ntab)       AND ((trx.column_ntab MULTISET             EXCEPT DISTINCT generated_ntab2) IS EMPTY) The problem is clearly related to the use of those nested tables. Now, there was clearly sufficient PGA for the nested tables themselves. So the problem was in executing the MULTISET-related functionality. We talked for a bit about dropping the use of nested tables and instead doing everything in SQL, to avoid the PGA error. That would, however require lots of wo...

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...
