Where's Wally? Or upcoming conferences for the first half of 2014 ....

By
Conference season has started as usual with RMOUG - where I've never been and still would love to go once. The conferences for the first half of the year where I will be presenting are listed below.

February 13, ODTUG online webinar
Together with Mia Urman I will be presenting "Running Oracle Forms from an APEX Application". About five years ago I wrote an article and presented about how to integrate Forms and APEX and this is another option in that area. You can join, for free, without travelling at the ODTUG site.

March 11, OUG Ireland, Dublin
Just like last year, I'll be attending Dublin early March. It's a very well organized conference in a beautiful venue. You can see all the presentations and all other information here. I'll be presenting "Best of both worlds: Create hybrid mobile applications with Oracle Application Express" - and "Finding the Needle in the Haystack or How to Troubleshoot an APEX Issue".

March 25, APEX World, Zeist
Officially the largest APEX-only conference in the world with an expected attendance of about 300 APEX enthousiasts. The complete - and impressive - agenda can be found here. I'll be doing the "hybrid" presentation again.

April 3-5, OUG Norway, Oslo - Kiel - Oslo
As most people know by now, this conference is on a cruise ship. So there's no escape ;-)
The agenda is awesome, with speakers from all over the world. Check this out. I'll be doing "An introduction into APEX" and "APEX and BI Publisher - a match made in heaven?"

April 29, APEX Usergroup, Düsseldorf
I've been invited to do a presentation at this event. Don't know which one yet...

June 5-6, OUG Finland, Helsinki
This will be my first visit to Finland. Really looking forward to this as the conference is somewhere outside of the city. I'll be doing the "BI Publisher" and the "hybrid" ones over there. The full agenda is not on line yet.

June 22-26, Kscope, Seattle
Last in the first half of 2014, but definitely not least, is Kscope. All information and the superb agenda can be found online. Apart from the stunning APEX agenda with three parallel tracks (I have to admit, I am biased, being the content lead) also the Developer Toolbox and Database tracks are very appealing to me. And then I didn't even mention the other tracks (Essbase, Hyperion, ADF & Fusion, EPM, BI & DWH) - until now that is...
Oh yeah, I'll be presenting the "hybrid" one again and "My first mobi - Starting mobile web development with APEX".

Hope to see you in one - or more - of these events!

Most presentations are sponsored by the Oracle ACE Program, extremely well organized by Vikki and Lillian.

Filtering in the APEX Interactive Grid

By
Remember Oracle Forms? One of the nice features of Forms was the use of GLOBAL items. More or less comparable to Application Items in APEX. These GLOBALS where often used to pre-query data. For example you queried Employee 200 in Form A, then opened Form B and on opening that Form the Employee field is filled with that (GLOBAL) value of 200 and the query was executed. So without additional keys strokes or entering data, when switching to another Form a user would immediately see the data in the same context. And they loved that. In APEX you can create a similar experience using Application Items (or an Item on the Global Page) for Classic Reports (by setting a Default Value to a Search Item) and Interactive Reports (using the  APEX_IR.ADD_FILTER  procedure). But what about the Interactive Grid? There is no APEX_IG package ... so the first thing we have to figure out is how can we set a filter programmatically? Start with creating an Interactive Grid based upon the good old Employ

apex_application.g_f0x array processing in Oracle 12

By
If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one: then you disable the " Escape special characters " property and the result is an updatable multirecord form. That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for

Stop using validations for checking constraints !

By
 If you run your APEX application - like a Form based on the EMP table - and test if you can change the value of Department to something else then the standard values of 10, 20, 30 or 40, you'll get a nice error message like this: But it isn't really nice, is it? So what do a lot of developers do? They create a validation (just) in order to show a nicer, better worded, error message like "This is not a valid department".  And what you then just did is writing code twice : Once in the database as a (foreign key) check constraint and once as a sql statement in your validation. And we all know : writing code twice is usually not a good idea - and executing the same query twice is not enhancing your performance! So how can we transform that ugly error message into something nice? By combining two APEX features: the Error Handling Function and the Text Messages! Start with copying the example of an Error Handling Function from the APEX documentation. Create this function
