Buttonsets are sometimes appropriate to represent a choice of selections instead of radio buttons. I think they look much better – especially when used for smaller lists. Sub lists can be shown or hidden easily using dynamic actions in APEX 4.

I’ve been moving some software I wrote a few ago, from Amazons cloud environment(EC2) to an offsite web farm here in Scotland over the last couple of months and thought I’d take the opportunity to freshen up the interface a bit. As I was now using Apex 4, I was keen to take advantage of [...]

In an APEX application i’m creating, I’m storing some output files that the public needs to get access to on the XMLDB server. The problem is, when i’m moving my code to production, I need to update the location to send the users to. Previously, I’d used global variables in a Global package to store [...]

Recently had a need for sticky hide/show regions in Oracle Apex 4.1. Here’s how I done it. Add the jQuery cookie library to your page template Added the following line to the hide and show region template ?View Code HTML1 $.cookie(‘#REGION_STATIC_ID#’,$(‘##REGION_STATIC_ID# .hide:first:visible’).length);return false; So my hide and show region template looks like this: ?View Code [...]

Pipelined functions are an extremely useful feature of Oracle 9i and above. They allow you to present disperate nontable based data as a standard table whilst streaming the output so that processing can begin immediately. I.e., they let you SELECT from a function much like you would SELECT from a table. Cool huh? Why would [...]

Many people seem to have trouble reading XML data within Oracle.

Oracle has a full library of routines built in to allow you to interrogate XML data. Unfortunately, they’re not very well documented.

Just say you have an XML file you want to be able to SELECT from. it looks like this:

HTTP, HTTPS, FTP, WebDAV including WebDAV Version Control Oracle XML DB is not a separate server; it is an integral part of the Oracle database, providing all of the high-availability, scalability, reliability and unbreakable security features needed to run mission-critical applications. You can use Enterprise Manager to manage and administer XML DB applications. The GUI [...]

Today’s bottom-line business impact of adopting XML technologies is especially important. For any organisation that shares information with its counterparts as a critical part of its delivelables, the creation of a single source of information from which we can deliver to all current and future media will deliver real, sustainable benefits. Faster time to market [...]

Why XML? XML (and its predecessor SGML) was developed as an answer to the desire for a single source format. XML represents any type of information in a media-neutral format. This enables automation, which speeds delivery, permits enhanced functionality, and reduces costs. XML has the additional virtue of being a standard without competition; virtually every [...]
