OOW 2009 : Thursday and wrap up

The day started easy: The first session had similar content as the last one of yesterday - which I didn't like too much - and the second one got cancelled. So a late start, what was fairly convenient because of yesterday's party...
The first one was by Arup Nanda about 11g New Features for DBA's. Since 11g is already 'old school', I didn't learned that much: physical / logical / snapshot standby databases (quite handy for testing in a real production environment, performing rolling upgrades and reporting); partition by reference (where you can easily keep master and detail data in the same partition) etc. I was hoping for more R2 stuff, but maybe it is just to early as that version was released just a couple of weeks ago.
The second one was all about Data Security. There are so many features and options regarding that subject. To name a few: VPD, FGA, Encryption, Data Masking, Advanced Security, Audit Vault, Database Vault, Label Security, Secure Backup.... I think it is time for a new SQL command: "alter database set security = high".
The last session of this years OpenWorld was done by Rich Niemiec. He is a great entertainer (throwing candy, bars, chips etc. in the audience, lots of funny stories) and managed to put over 200 slides in 1.5 hour - what was only half an hour over time. This session was also called "11g New Features" - but this time not only for DBA's. And again, not many things that I haven't heard before.
That night Andreas surprised his housemates with a real gourmet dinner (with bison steak). And that was a really good closure of what should become a tradition: the Holland ACE House! Thank you Andreas, Jacco and Marko for your great company this week. And of course a special big THANK YOU for Anjo: He made this all possible!

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...

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.
