New entry page for my Oracle APEX activities


Some time ago I have registered the domain oracleapex.info and I finally found a few spare minutes to create an entry page for all my Oracle Application Express (APEX) activities.

I want to move all my APEX related open source projects to this domain. The Oracle APEX Builder Plugin is already hosted there and for my new project, Oracle APEX Essentials I have created a new web page today. The ApexLib Framework should also follow as time permits. I’m having a busy schedule lately.

BTW, I’m still looking for more beta testers for Oracle APEX Essentials. Get the details here.

Caution with new “Runtime Where Clause” in Oracle APEX 3.1

Found out the hard way that the new property “Runtime Where Clause” for processes (eg. Fetch, DML) has a serious bug. The value of the property gets exported and is contained in the export file of an application, but it isn’t set when you import an application!!!

Because most of us are not developing on the production system, that bug is a real show stopper for that feature, because you never get the identical application onto the production system or to the customer.

The problem has been reported and according to Scott from the APEX team, it’s getting fixed in 3.1.1

Note: The “Optional Where Clause” of “Get Next or Previous Primary Key Value” processes is not effected by that behavior, this property was already available before Oracle APEX 3.1

Integrate Speech Recognition into Oracle APEX

Tyler Muth has posted a really cool example on how to integrate Oracle APEX with another service.

Jott is a speech recognition service and allows to integrate third party applications into there service. Tyler used this mechanism to write the output text of the speech recognition into the table of an Oracle APEX application. Read all the details on his Speech to text to Oracle APEX posting.

Great work Tyler!

Too bad that the service is not available in Europe :-(

ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.

If you get an ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc. from your DML process when you submit the changes in an Oracle APEX application, then this is because Oracle APEX tries to lock the effected record before it updates/deletes it. This behavior was introduced in Oracle APEX 3.0, but with the side effect that complex updateable views with an instead of trigger get the above error.
