Welcome, Connor McDonald, to the Oracle Developer Advocates team!

I am very pleased to announce that as of 15 June 2015, Connor McDonald, ACE Director extraordinaire, recognized worldwide for both his depth of knowledge on Oracle Database and his excellent presentations, is now an Oracle Developer Advocate for SQL.

Welcome, Connor!

Connor McDonald has, over the past 18 years, worked with Oracle Database systems in Australia, the UK, Southeast Asia, Europe, and the United States. 

He has co-authored three books, and has been a popular speaker at Oracle conferences around the world, specializing in topics on the database engine, in particular SQL and PL/SQL. He has twice won the Inspirational Speaker award by the UK Oracle User Group in 2009 and 2011.  Whether speaking in a full day seminar to a room of developers, or just a "Hey, check out this cool feature" to the person sitting next to him, Connor has always loved sharing information about technology with others.  

While working for clients over the years, Connor realized that the most satisfying part of his job was seeing others grow and develop their skills in Oracle Database technology, helping them discover the amazing things of which the database engine is capable: so much more that simply the place where the bits and bytes are stored.  

When Connor saw the Oracle Developer Advocate team being formed, he asked himself: "So why not take this to the next logical step, and accomplish the same thing on a larger scale?"

Fortunately for Oracle and the Oracle Database user community, Connor answered that question with: "Yes, why not? Let's do it!" To which I agreed with great enthusiasm.

I greatly look forward to the presentations, videos, quizzes, trainings and more that Connor will be unleashing upon the world. 

As many of you likely know, Connor is tucked away in Perth, Australia, so if you are coming to Oracle Open World, be sure to take advantage of the opportunity to congratulate him in person. I sure will!

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: Save your source code to files

PL/SQL is a database programming language. This means that your source code is compiled into  and executed from within the Oracle Database. There are many fantastic consequences of this fact, many of which are explored in Bryn Llewellyn's Why Use PL/SQL? whitepaper. But this also can mean that developers see the database as the natural repository for the original source code , and this is a bad mistake to make. It's not the sort of mistake any JavaScript or Java or php developer would ever make, because that code is not compiled into the database (well, you can  compile Java into the database, but that's not where 99.99% of all Java code lives). But it's a mistake that apparently too many Oracle Database developers make. So here's the bottom line: Store each PL/SQL program unit in its own file . Use a source code control system to manage those files. Compile them into the database as needed for development and testing. In other words: you should never kee...
