KScope 11 - Sunday

By
The first day (or pre-conference day) was filled with four full day Symposium sessions. The APEX one I attended was completely filled by the APEX Development team itself. 
Joel Kallman kicked the day off with a nice story about the development of APEX, the tools they used etc. Then there where three more sessions about Tablular Forms, Interactive Report and Webservices - all pointing out the new APEX 4.1 features. 
The coolest one of the day was Marc'Sewtz's presentation on APEX for Mobile Devices. He showed that, using HTML 5 in your template, you can create real native-looking applications for mobile devices. You can already do that using the current version of APEX, but the 4.1 will also contain support for special mobile actions, like rotate and tap - so you can create Dynamic Actions on these events. As jQuery Mobile, the framework they're using, isn't production yet, probably some of these mobile features will be disabled in the first release of 4.1. 
Mike Hichwa had the keynote as the last session of the day. He outlined the plans for APEX after 4.1. Next on the wish list are more cool functions like a Modal Dialog, Multiple File Upload etc. It seems that every good plug-in out there will be added as standard functionality! Als providing RESTful web services will be a feature of an upcoming APEX release  - using the power of the APEX Listener.Talking about APEX Listener...some BI Publisher functionality might be incorporated in the AL, so the AL then can be used for generating PDF documents - a sort of "BI Publisher Light"...
Last but not least: Did you know Oracle uses an APEX application for their partner store and orders with a total worth of 4 billion dollar go through it....so, who dares to say APEX can't be used for business critical applications and is only suitable for small department level ones?

Fix Interactive Report headers issue when using a Region Display Selector

By
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?

By
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

By
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...
