OOW 2009 : SUN-rise on a SUN-day

This week I am in San Francisco for my third Oracle Oracle Open World. Because it was my second consecutive visit I received an "Oracle Alumni" tag (for my badge) and a nice jacket during registration.
This Sunday the first session (at 800 AM! - OOW is really hard work...) was by...me! There were around 50 to 60 attendees, and IMHO that's not too bad for a session at that time. The session seemed to be interesting enough for 111 people to include in their schedule, but I guess for a few of them it was too early after all...
The session went ok, not great, but ok. I would rather do a session after being a couple of days in the US, because then you're more used to the language. This one was within 20 hours of arrival.
Right after my session - and a well deserved cup of Starbucks coffee with Edwin - I went back to the "Holland ACE House", where I am staying with Marco, Andreas and Jacco, to drop off my laptop. BTW the house, rented by Anjo (thanks mate!), is very nice. You can see the pictures here. Right after that I went back to the Moscone for some sessions within the ODTUG track. They were all about migration to APEX. One company moved from Access to APEX, another from PowerBuilder / Cobol / to APEX. Another proof that APEX is suitable for smaller (Access like) apps as well as Enterprise level applications.
After that on to the Hilton for a presentation by "Mr PL/SQL" : Bryn Llewellyn, about OnLine Application Upgrade. Bryn thoroughly explained the goal and the use of the new 11gR2 feature "Edition Based Redefinition".
Meanwhile I missed the APEX 4.0 session (I have seen the major part of it at last June's ODTUG), but it was very well received. If you're interested you should take a look at Lucas' blog post.
Then off to the impressive Hall D for the opening keynote of this year's OOW by Scott McNealy, the chair man of Sun. He did a good job presenting two top tens - in an almost Oracle-red sweater. Also on stage came James Goslin, the inventor of Java. Dresses in an old jeans and a baggy T-shirt he perfectly fitted the description of a Java nerd. Scott introduced "his hero" (what sounded a little bit sarcastic): Larry Ellison. Larry, again, stated that Oracle will spend more money on the development of SPARC, Solaris and MySQL than Sun would do. Apple already proved that the combination of delivering hardware and software can be successful, so why can't Oracle do something similar?
The main part of Larry's talk was aimed at IBM. Larry stated that IBM is more expensive, uses more electricity (that's why they call it the "POWER" processor ;-) ) and not fault tolerant. Suns runs Oracle twice as fast than IBM. Larry also announced a new chapter in the Oracle - IBM competition: If your database doesn't run two times faster on Oracle/Sun than you'll win 10,000,000!

In the evening the ACE dinner was organized on a nice location near the Bay Bridge.

Fix Interactive Report headers issue when using a Region Display Selector

When you have multiple Interactive Reports (IR) on your page and use a Region Display Selector to mimic tabs, you might notice some weird behaviour in the IR headings if you switch tabs. The headings are not positioned correctly and you get an extra empty row under the headings. It just looks weird and ugly. But if you resize your browser window, it all looks fine again (until you switch to another tab..) So can we fix this by creating a Dynamic Action that mimics that "browser window resize" event? Yes we can! Create a Dynamic Action that fires on Click of the jQuery selector li.apex-rds-item a . That should fire a JavaScript snippet :  apex.event.trigger(this.triggeringElement, "apexwindowresized"); So now a click on a tab not only switches from one IR to another but also fires that event that will "autofix" the IR headers. A simple solution for an annoying problem. This applies to APEX 5.0, I assume it will be solved in 5.1.

How to create neatly formatted Excel documents using PL/SQL?

If there is a requirement to produce output from an application into Excel, you would probably create a CSV (Comma Separated File) with the data and start Excel to show the data - at least that's what I did...until now. The drawback of this solution is that you could only produce data and no nice layout. But Excel is also capable of opening HTML-files and using this you could create Excel files with data and magnificent layout! Let me give an example: 1. Create a procedure to show the data in formatted in an HTML table. CREATE OR REPLACE PROCEDURE display_emp_list IS v_emp_count NUMBER(5); v_empno NUMBER(8); v_ename VARCHAR2(50); v_job emp.job%TYPE; v_sal emp.sal%TYPE; v_bg_color VARCHAR2(10) := ''; CURSOR c_emp IS SELECT empno, initcap(ename), job, sal FROM emp ORDER BY ename; BEGIN SELECT COUNT(*) INTO v_emp_count FROM emp; owa_util.mime_header('application/ms-excel', FALSE); htp.p('Content...

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid . The use case I'll cover right here is probably more common - and therefore more useful! Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user. The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even wors...
