Reading the Oracle Documentation the Easy Way

Personally I don't like reading documentation from my computer, I prefer to have a "real" book. So when Oracle 12c came out I wanted to read the New Features guide and the Concepts guide again, but the fact that I would have to read it off my computer screen stopped (more...)

APEX: Using the Application Date Format Mask

In your APEX application, you can define several default format mask to be used throughout the application, such as the Application Date Format or the Application Date Time Format. This eliminates the need to specify the format mask for each Date Picker item that you use. It helps in keeping the application at least consistent regarding the format mask used.When you want to do some validation in your forms using the Dates entered by the enduser, you might have a need for the Application Date Format.So instead of hard coding (using the same format mask as you entered):

APEX: Highlight a Record in Report – with Dynamic Action

Yesterday I wrote a blog on how you can highlight a record in a report. That blogpost can be found here.Learco Brizzi posted a comment on a different way of accomplishing the same thing. And there are probably a number of other possibilities to implement the same requirement.In this blogpost I want to show you how to do the same with a Dynamic Action. Why would you want to choose for a Dynamic Action? This is a more efficient way because you don't need to refresh the page or the region. This blogpost will use a report based (more...)

APEX: Highlight a Record in Report

Yesterday I read a question which was posted as a reply to an earlier blogpost. The orginal blogpost was about how to make a Report Row clickable, instead of just the Edit column.The question was: "How do I keep the clicked row highlighted so I can keep it as context information?"To see a working example of the requirement, check out this sample pageIn this blogpost I will provide a step-by-step way of doing just that.For this to work properly, you will need a page with a report. In this blogpost page 9 will contain a (more...)

APEX: Dynamic Action in Interactive Report

Yesterday I was showing a colleague how to use a Dynamic Action in an Interactive Report to do an update on the underlying table. To get this to work prior to APEX 4 you would need to write some javascript on the page as well as an Application Process. Mostly I used the method described by Roel Hartman a number of years ago.
Want to take a look at a demo first before the steps to take to make it work? It's right here.
For this example, I will use a simple table named TASKS:
create table TASKS

ACED Nordic Tour 2012: 4 days, 4 countries

Can't believe it's almost two weeks ago. Together with Mark Rittman, Carl Dudley, Sten Vesterli, and Tanel Poder, I was invited to join in for the ACED Nordic Tour.During the Nordic Tour we visited Denmark, Sweden, Norway and Finland.

They were kind enough (more...)

OOW 2012: Little things make me happy

Yesterday evening we had the annual "We went to OOW and this is what's new in the world we call Oracle" at AMIS. Starting around 5pm and ending around 10pm a lot of information was presented by several AMIS colleagues.My contribution to the evening was (amongst others) a little bit of new features in SQL and PL/SQL, only a little bit as there is too much to cover in just 20 minutes. It's the little things that make me happy. What is the little thing that I like?When you define a table you can assign a default value (more...)

SQL Developer tip: Don’t open the table

One of things I don't like about Oracle SQL Developer is that if you are browsing and clicking on tables, it can automatically open the table on the right side of the IDE.
There is a simple way to switch that off, just heard how to switch this feature off. Navigate to the Preferences settings:
Goto Database >> Objectviewer, and uncheck the tickbox labelled "Open Object on Single Click"
And that's it.
