Tips for Writing PL/SQL in APEX Apps
Ah, the joy of a low-code development tool like Application Express! You point, you click, and you get beautiful, powerful websites and mobile apps. But you will also almost certainly need to write some SQL and PL/SQL to complete the functionality of that application. Sadly, there is always a tendency when writing code within a point-and-click development environment to treat that code rather casually; after all, it is not the really important (user-facing) part of the application, right? Wrong! It’s all important, and it is way too easy to create an awful mess in your otherwise elegant APEX app if you treat your SQL and PL/SQL code as “second class citizens” in terms of the attention you give to it. Not to mention bad performance or maintenance nightmares!
In this session, three expert APEX developers (Karen Cannell, Scott Wesley and Scott Spendolini) offer recommendations for how best to write and manage your SQL and PL/SQL in your APEX applications, with attendees chiming in - we are certain! - with their own suggestions.
