With an Interactive Report you can choose whether you want the Actions Menu to be shown or not. This has to be done by the developer. Of course the customer wanted to have this based upon the existing authorization scheme. How can you solve this?
Happily I would announce the listing of my upcoming book at PacktPub publishers website. The book is expected to be released by May, 2012. The book is for the Oracle Associate professionals who are aspiring for Professional level exam (1Z0-146 certification). “The Oracle Advanced PL/SQL Developer Professional Guide helps you master advanced PL/SQL concepts.
Somebody asked for a simple comparison between a PL/SQL pass-by-value function and pass-by-reference procedure, where the procedure uses only an
OUT mode parameter to return the result. This provides examples of both, but please note that a pass-by-value function can be used in SQL or PL/SQL context while a pass-by-reference procedure can only be used in another anonymous of named block PL/SQL program.
It seems that CBO can work with the line comment inside sql hints.
Let’s see. I create a table with 3 indexes:
--drop table ttt purge;
create table ttt
a number not null,
b number not null,
c number not null
insert into ttt
from dual connect by level <= 10000;
create index iiia on ttt(a);
create index iiib on ttt(b);
create index iiic on ttt(c);
And then I’m able to switch access paths by commenting:
One of the Q4 2011 playoff quizzes examined the way that user-defined exceptions are handled. If you didn't participate in the playoff, you may want to view this quiz - even try to answer it for yourself - before reading this post.

The 25 January quiz tested your knowledge of the minimal amount of code needed to "create" a PL/SQL procedure in the data dictionary, even if the resulting program unit is invalid.
The choices offered were:
CREATE PROCEDURE plch_test;
CREATE PROCEDURE plch_test AS;
CREATE PROCEDURE plch_test NULL;
CREATE PROCEDURE plch_test IS BEGIN NULL; END;
The first was scored as incorrect and the last three as correct.
20th century has been highlighted by the two notable insights onto the nature of information. In 1948, Claude Shannon published classic paper “A Mathematical Theory of Communication” suggesting quantitative information measure — entropy — as average number of bits needed to store or communicate one symbol in a message. The paper has tremendous impact: it launched the whole new discipline — the Information Theory.
This week I attended a webinar by Cary Millsap, organized by Red Gate. It was called "Real Developers DO use Tools" and was focussed on, well, tools. At the end of Cary's talk, James Murtagh showed a demo of their Schema Compare tool. The demo wasn't flawless, but he recovered nicely :) (note to self: don't do live demo's).
