The power of using records in APEX III

TweetShareSharePin0 SharesIn this post I’ll finish up the CRUD implementation using records, procedures and views. This series of blog posts started with this post which was followed by this. At this point we have a working report that links to a form. The report is based on a view and the form is based on a procedure. At this point the form is only loading the record in using a procedure that uses a record in its signature. In this post […]


The power of using records in APEX II

TweetShareSharePin0 SharesIn this post I follow up on the post where I started talking about records in APEX. In this post I’ll show how to add a page in front of the form created in that post. Thus this post will show a report and let you navigate to the form where the selected record is displayed. Pretty basic stuff, but it allows better testing of the form and it sets the stage for showing how to make the form […]


The power of using records in APEX

TweetShareSharePin0 SharesDo you use forms based on procedures in APEX? If not, why not?Do you use records in the procedures you use for forms in APEX? If not, why not? I like procedures and records and with APEX I like them even more. Why you say? Should you not just point forms against tables and let the APEX magic take care of it all? No, I do not think you should. The reason is that I love that feature for […]

OOW 2010 Develop Keynote

TweetShareSharePin0 SharesYes, this post is a little out of order as it clearly didn’t take place after the Thursday afternoon sessions.

It was held by Tom Kyte and the subject was “What’s new in database development”. It’d be more correct to say Oracle development than database development as […]

OOW 2010 Wednesday Morning

TweetShareSharePin0 SharesWednesday starts off with a presentation about a new feature in APEX 4.0 that I have not had a chance to look into. It is how you use and develop plugins. The presentation was held by Patrick Wolf who is also the developer of the plugin feature. Scott began by showing how a plugin is used (that is using a plugin compared to developing it). You install a plugin by selecting plugins in the shared components section, and then it […]

OOW 2010 Monday Afternoon

TweetShareSharePin0 SharesThe afternoon was kicked off with a presentation on using APEX in large projects by Dimitri Gielis. These re my notes for what Dimitri told us. Many people feels that APEX cannot be used for anything larger than a singe developers app.  Sumneva uses EC2 for both demo and development work with their clients. They have readymade scripts to create new projects that sets up filesystem directories, APEX application, and subversion. They’re finding that the agile project methodology works […]
