If your Oracle APEX Application requires different types of access - full access or readonly - for different types of users, you can specify a Read Only Condition on Page level (or Region, Item, Button, etc.).
You can set an Authorization Scheme on Application level, so it'll be applied to all pages. So if you have an Authorization Scheme named 'User Can Access Page' defined by a PL/SQL function like this:
APEX 5.0 will be released between now and the end of May. People who have already spent some time on the Early Adopter versions know this version is packed with new features aimed to make APEX developers even more productive, like the Page Designer.
Another striking new subset of features is aimed at creating better looking user interfaces for your APEX applications in an easy and maintainable way.
While waiting at the airport for my plane back to Amsterdam, I have some time to write down my experiences of the last few days in Riga.
After arriving in the hotel, I walked to the old part of town and strolled around. The old part looks very medieval (it is - so no surprises there) with cobblestone streets, old houses and very few cars. Nice!
Then back to hotel, in time for the "official" (more...)
After some thought, I decided I will be running for the ODTUG Board of Directors this year. I have been attending Kscope since 2008 (New Orleans). Presented at Kscope and APEXPosed since 2009. Did a few webinars. Was a member of the APEX Content Team for Kscope12 and 13. And now I am the Content Lead for the APEX track for KScope14 and Kscope15. So I like spending my free time for ODTUG, to keep (more...)
Yesterday the first ORCLAPEX-NL Meetup was held. Finally. We seemed to be a little behind other locations - but pretty sure we'll catch up quickly!
After (a lot of) great pizza - kindly sponsored by smart4apex
- and a round of introduction of every attendee, Richard kicked off the meeting by explaining the concept of these kinds of meetups. He also gave a nice review of his first experience of Kscope during Kscope14.
Yesterday I attended the first ORCLAPEX-BE Meetup. Very well organised by Dimitri and Roeland. Remarkable fact: I was not the only "foreigner" as around 30 - 40% of the - around 16 - attendees where Dutch! So Meetups can even easily cross borders ...
So after some initial socialising....
... Roeland explained the concept of these kind of meetups.
In the next hour Dimitri went over all the great new features of APEX5, like Page Designer, (more...)
It is still a long time before Kscope15. But if I look at the website
.... I can hardly wait!
A good conference needs a good time for preparation. An awesome conference .... needs even more time. So that's why we need your abstracts a.s.a.p. After the close every member of the review committee will go over every abstract and will give it a rating and a comment. When that's all done, the (more...)
the meetups are more or less global nowadays!
And even in The Netherlands we will officially join this virtual group and have our first ORCLAPEX Meetup on Thursday September 18. The location is central and well known: The Dutch Oracle HQ alongside the A2 highway. (more...)
The last two weeks I wrote a daily blogpost about a new feature in APEX 5. And intentionally I didn't cover the "big" features, like the new Page Designer, the Modal Pages, the Universal Theme etc as these probably are - or will be - covered by other people. So in my 10 blogposts I covered "Ten Tiny Things
For those who missed it - all or parts of it - herewith (more...)
To get a proper list of the new packages and API's APEX 5 provides us, we have to wait for the documentation of course. But if you're impatient and want to now more, you can get a list of all package procedures and functions by running this SQL on the APEX 5 Early Adopter instance:
select distinct s.synonym_name, p.procedure_name
from all_procedures p join all_synonyms s on p.object_name = s.table_name
In APEX 4 you can define Authorization Schemes. This is a very useful feature to prevent code repetition all over the place. For instance and Authorization Scheme "Is Admin" might use a select on one or more tables (or web service calls or whatever is necessary) to determine whether a user, the :APP_USER, has an Admin role or not. And you can use any value in session state, like :APP_ID or :APP_PAGE_ID in your query (more...)
In APEX 4.x the developer could implement a feature that involves a call to the APEX API. E.g. you could create new pages on the fly if you would like to (just examine an export file for the how-to). You could drop an application using a procedure from the APEX_INSTANCE_ADMIN
package. You could drop a user using APEX_UTIL.REMOVE_USER
. If this is all on purpose and secured than that's fine. But maybe you (more...)
Now and then it happens when we're logging in into our APEX instance: We have to change our password again .... And that means, typing it in an awful number of times:
1. Current Password
2. New Password (and of course preferably the same as the current one ...)
3. Confirm New Password
4. Press Apply Changes
5. Press Retun
6. And we're back at Square One : The login screen - and here we type (more...)
As a lot of the new APEX 5 features are "by developers for developers
", this one is also a nifty little thing that make our lives easier. Only the developer part of our lives of course....
In the upper right corner of APEX 5 you'll see your login name and a rather anonymous avatar. Just for fun - and recognisability - you can add your own face there. Or a picture of your (more...)
Oracle Open World 2014 starts in just over 4 weeks from now. And I am one of the (50,000?) lucky people who will be there ....
I will even take part in three sessions, one straight at the start and one almost at the end:
What Are They Thinking? With Oracle Application Express and Oracle Data Miner [UGF2861]
Sunday, Sep 28, 9:00 AM - 9:45 AM - Moscone South - 304Panel Discussion: Bring Your (more...)
In the current version of Oracle Application Express you could use up to three items in a Column Link.
Most of the times that is enough. But there were always some use cases where you needed four or even five. And of course, just like with all limitations, you can figure out a work around. But wouldn't it be just awesome if APEX offers us more items out of the box.
