Pro Oracle Application Express - Now Shipping

In case you missed it, the book that I contributed to - Pro Oracle Application Express - has finally shipped!

According to the Oracle Bookstore at OpenWorld, it was the hottest book there, at least according to this site:

So if you were one of the many who pre-ordered it, you should have it by now and I personally thank you for your patience!  I hope that you get out of it as much as we (especially John) have put into it!

I think it would be a valuable reference to improve my APEX development and I'd like to buy it.

But I have a little problem, I am from Lima, Peru and it looks like this book doesn't get shipped here. I wander if there is a downloadable ebook or pdf version of this book so I can buy online and get it.

Not sure what you can do. I'd start by contacting Apress, which is the publisher:

They may be of more assistance.

I've bought and downloaded the ebook from the Apress Web.

Thanks for your help

May I post a question here about a topic in the last chapter of Pro Oracle Application Express? It is in reference to Using the API: Adding Items to your Pages?
Steve said…
First, I realize the following is "unsupported" and I have heeded your "Use with Extreme Caution!" warnings.
I am using a pl/sql process in one page to create page items (radio, checkbox, text) on a second page using: wwv_flow_api.create_page_item(...)
During the creation process I am storing the names of the created items in a table. :P10_Q1, :P10_Q2, etc. Works well.
Now I want to be able to allow user input using the created items, and store the results in a result table. I use a cursor to retrieve the page items names from the table. My insert statement using the cursor pointer inserts the name of the page item, not the page item value. Kinda vague as I'm trying to be brief. More details posted at:
Really appreciate your help.

You're correct - that process is unsupported, and unfortunately, even if I was aware of how to use it correctly, I would not advocate it or share it.

If you're trying to create a survey, you may want to look at using APEX_ITEM API calls - which are fully supported.

This approach would still support your requirements as outlined in your OTN Forum post, but only use a single page. If you create a smart data model, you should be able to facilitate the creation of any number of questions and then use APEX_ITEM to dynamically generate the corresponding updatable reports and not have to dynamically create any APEX items.

Have a look at this example:

While it's a bit old, the data model and concept has not changed at all. It should also install into APEX 3.1 without any issues.

I'll venture back into supported territory. Thank you for your time.

Logging APEX Report Downloads

A customer recently asked how APEX could track who clicked “download” from an Interactive Grid.  After some quick searching of the logs, I realized that APEX simply does not record this type of activity, aside from a simple page view type of “AJAX” entry.  This was not specific enough, and of course, led to the next question - can we prevent users from downloading data from a grid entirely?

I knew that any Javascript-based solution would fall short of their security requirements, since it is trivial to reconstruct the URL pattern required to initiate a download, even if the Javascript had removed the option from the menu.  Thus, I had to consider a PL/SQL-based approach - one that could not be bypassed by a malicious end user.

To solve this problem, I turned to APEX’s Initialization PL/SQL Code parameter.  Any PL/SQL code entered in this region will be executed before any other APEX-related process.  Thus, it is literally the first place that a developer can interact with an APEX page…

Thanks, ODC (Oracle Developer Community)!

I owe a lot of thanks to the ODC - which stands for Oracle Developer Community.  What is ODC?  You may remember it as OTN, or the Oracle Technology Network.  Same people, different name.  Why they changed it I can't say.  People just liked it better that way... (love that song)

In any case, what am I thankful for?  A lot.  To start, the tools that I use day in and day out: SQL Developer, ORDS, Oracle Data Modeler, SQLcl and - of course - APEX.  Without these tools, I'm likely on a completely different career path, perhaps even one that aligns more closely with my degree in television management.

While the tools are great, it's really the people that make up the community that make ODC stand out. From the folks who run ODC and the Oracle ACE program to the developers and product managers who are behind the awesome tools, the ODC community is one of, if not the greatest asset of being involved with Oracle's products.

Custom Export to CSV

It's been a while since I've updated my blog. I've been quite busy lately, and just have not had the time that I used to. We're expecting our 1st child in just a few short weeks now, so most of my free time has been spent learning Lamaze breathing, making the weekly run to Babies R Us, and relocating my office from the larger room upstairs to the smaller one downstairs - which I do happen to like MUCH more than I had anticipated. I have everything I need within a short walk - a bathroom, beer fridge, and 52" HD TV. I only need to go upstairs to eat and sleep now, but alas, this will all change soon...

Recently, I was asked if you could change the way Export to CSV in ApEx works. The short answer is, of course, no. But it's not too difficult to "roll your own" CSV export procedure.

Why would you want to do this? Well, the customer's requirement was to manipulate some data when the Export link was clicked, and then export it to CSV in a format…
