Obsessed with Oracle PL/SQL

Before I joined Oracle, I was honored to be an ACE Director for several years, and boy did I get spoiled. Especially at Oracle Open World time. Oracle paid for my airfare and hotel. They set up the hotel reservation. They picked me up in (non-stretch) limo and delivered me to that hotel. They drove me back to the airport. Nice.... Then I rejoined Oracle in March of this year. In late August, I was talking with a friend at Oracle and mentioned that I had yet to arrange my hotel. "Whaaaat?" she practically screeched in the phone. "You don't have your hotel? Oh, Steven, you better get on that right away." Turns out I had received an email on 7 July saying, in effect, "Congrats, Steven as Oracle employee. We have confirmed your registration for the now. NOW GO RESERVE YOUR HOTEL ROOM." But I didn't notice that last part. Just filed the email away. So I followed the advice of my friend, and went on-line to get my hotel reservation set up.

Received this question today: I don’t have a problem to select from collection when collection is based on objects with columns/attributes. What about a collection defined as: TYPE list_of_numbers_t IS TABLE OF NUMBER; What would be the column name when you select from the collection? Short answer: COLUMN_VALUE Longer answer: here's a script I used to demonstrate several different features of nested tables. See query at bottom. CREATE OR REPLACE TYPE list_of_names_t    IS TABLE OF VARCHAR2 (100); / GRANT EXECUTE ON list_of_names_t TO PUBLIC / DECLARE    happyfamily     list_of_names_t := list_of_names_t ();    children        list_of_names_t := list_of_names_t ();    grandchildren   list_of_names_t := list_of_names_t ();    parents         list_of_names_t := list_of_names_t (); BEGIN    /* Can extend in "bulk" - 6 at once here */    happyfamily.EXTEND (6);    happyfamily (1) := 'Veva';    happyfamily (2) := 'Chris';    happyf

We've been hitting a snag of late with new registrants at the PL/SQL Challenge . As with many sites, to ensure that a person's email is not being hijacked, we send an email with a verification URL. It was working for quite a while, but then we noticed players reporting a bug: On clicking the verification link am getting an error message like: The PL/SQL Challenge website is temporarily unavailable. Please try again later or join the PL/SQL Challenge twitter group: PLSQLChallenge Sorry for the inconvenience. Ugh. Well, the site is certainly available. So what's going on? Turns out the verification URL is missing the all-important "/pls/": This: http://www.plsqlchallenge.com/apex/f?p=QDB_PROD:34:::::P34_USER,P34_CODE:... should be this: http://www.plsqlchallenge.com/pls/apex/f?p=QDB_PROD:34:::::P34_USER,P34_CODE:... Looked into the code and found:    FUNCTION apex_website_url RETURN VARCHAR2    IS    BEGIN      

Received this note from a PL/SQL developer today: I have an idea to build the database of my application in such a way that all DML operations for the application are managed at the back end. There should be generic functions/procedures that will perform the DML operations. Also there should be functions developed that will provide the "Select" data. In short, I want to remove all sort of DML from front end and bring them to back end. In case of any DB structural changes, we should not require a large development effort. For example, if we have to add couple of columns to a table then it should be easily manageable/configurable in order to minimize the development effort cost. This is the sort of note that makes me happy. I have proposed for years to Oracle Database developers that we should see SQL as a service that is provided to us, not something we should write over and over and over again in our "high level" application code (as opposed to low level gener
