New Ranking Tags Feature of Oracle Dev Gym

                                

You can take quizzes, workouts and classes at the Oracle Dev Gym solely with the objective of learning and improving your expertise in Oracle technologies.

You can also play competitively, which means that you will be ranked when you take a tournament quiz. You can see all the rankings for tournaments by clicking on the Leaderboard tab.

But what if you'd like to see how you ranked compared to your co-workers or friends?

What if your entire dev team wants to take a workout together and then compare how you all did?

I have one answer to those questions: ranking tags!

Click on your name in upper right, select Profile Settings.

Click on the Ranking Tags tab.

It's empty! OK, now it's time to talk to your friends or co-workers. Decide on a tag that you can use to identify your little circle. Aim for something obviously unique. These are "just" tags, so if you use something like "ORADEV" and so does someone else, you will be in the same ranking filter list.

So decide on a tag, invite your friends to do the same thing. You can see everyone with the same tag in the profile settings page.

Once you've done that, you can choose the tag both on Leaderboard ranking reports and on a new Workout Rankings modal. You will see a button to open this modal when (a) you've completed the workout and (b) you've added at least one ranking tag to your profile.

The two minute video above shows you all of this. Enjoy!

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...
