It's Christmas time... It's a time for giving... It's a time for warm-hearted feelings...But there are people battling for their lives against cancer, who may not have much energy left to enjoy the holidays. Almost everybody has family or friends whose life has been impacted by cancer. Let us all reach out however we can, help wherever we can, and let good thoughts go out to the victims.
For most of this year, we have offered two weekly, competitive quizzes on PL/SQL:
PL/SQL Challenge & PL/SQL Explore
But it doesn't really make sense to offer two different championships. At least, that's how I, the fellow who would write all those quizzes, feels about it.
There is, as one might expect, lots of overlap between the top 50 ranked players in the two quizzes: only 14 in PL/SQL Explore are not in PL/SQL Challenge's top 50.
It seems to me that it makes much more sense to have a single championship for PL/SQL, overall.
I’m on my way to UKOUG Tech14, where I will present Database 12c MATCH_RECOGNIZE: Beating the Best Pre-12c Solutions on Tuesday at 3 P.M., room 4B.

So we've had taxis for years and we know that generally taxi drivers work hard, long hours and make small amounts of money. The cab companies make more, of course, but I don't think there are a whole lot of billionaires in the taxi business.
Sure, "trepidatious" might not be a word, per se.
But I am confident it is something that more than one very famous male actor is feeling right now, as they watch Bill Cosby go down in flames.
As in: seriously and deeply apprehensive about what the future might bring.
There are a few things we can be sure of right now, even if Cosby never faces a judge or jury:
1. Bill Cosby is a nasty piece of work, and very likely (was) a pedophile.
If you’re not using Toad DBA Suite, it’s sometimes hard to find solutions. Somebody wanted to know how to find indexes that aren’t that aren’t indirect. Indirect indexes are those created for a primary key because a primary key column or set of columns are both not null and uniquely constrained. You can’t drop a unique index for a primary key without dropping the primary key constraint that indirectly created it.
When you load data with an "effective date" into a Data Warehouse, what happens when the new data is the same as yesterday's? Do you add a new record with the new "effective date" or do you update a date range in the existing record? If you want to maintain date ranges, try the 12c MATCH_RECOGNIZE clause.
Saw Interstellar last night. Only had to wait through TWENTY MINUTES of trailers. Had to put fingers in my ears for much of it. So loud, so invasive, so manipulative. Anyway....
Whenever you call the Oracle database to change data, the result will be all or nothing: Oracle will either do everything you asked it to, or nothing at all. This is true for SQL and PL/SQL.
