Below is a direct copy and paste of some code I ran (nothing is done in between the sections). There’s clearly data in the tables, but it vanishes when they are joined:
On one of the pages there was a need to refresh a report region when a node in an APEX Tree was clicked. As far as I know there is no built-in method to create a Dynamic Action to a node in an APEX Tree, so this might call for a Custom Event.
If there is a built-in method, please leave a comment :)
My father, Sheldon Feuerstein, was a large presence in our lives and the lives of many others. He was a big man, physically (and, sadly, overweight for too many of his later years, which contributed to the diseases that led to his death in 2010), but it was more than that. He was smart and honest and eloquent. He could also be very stern and, before he passed middle age, manifested quite the temper. But he was a deeply compassionate man, especially for members of the family. Many nieces, nephews and cousins remember him with a love and deep fondness that sometimes surprises me.

My students required way to remove all their tables, views, and constraints from a MySQL
database (or the alias
schema). Since they’re using referential or foreign key constraints, I also wrote one procedure to drop all foreign key constraints from a database. There’s also another to drop views. The final stored procedure calls the procedure that drops foreign keys, then calls the procedure to drop views before dropping all the tables.
dropForeignKeys stored procedure:
In teaching, I had a problem because my students have different base operating systems, like Windows 7, Windows 8, Linux, and Mac OS X. I needed a teaching and lecture platform that would let me teach it all (not to mention support their environments).

dbms_output.put('Just ignore it...');
dbms_output.put('...it'll go out soon!');
This is a re-hash of my very first post. I wouldn’t normally repeat myself, but I’ve just been horribly burned by some code with “when others then null” blocks.
