Oracle PL/SQL : learning new and advance techniques

Someone asked this question:

I have passion for Oracle PL/SQL and learning new and advance techniques as well. Well my current Job does not require this a lot. How can I be in touch with Oracle PL/SQL advance topics and tricks as I am not able to code much


My Reply:

This is what you can do. http://tryapexnow.com/ : You can create some sample application here. This is Oracle application express and you can create your own applications. Write as much code as you want. This is free tool provided by oracle corp.

http://tryapexnow.com/: You can review Oracle application Express by participating in the Early Adopter release.

If you are working on earlier releases of Oracle, try 11g new features.
