Video : Online Segment Shrink for Tables : Free Unused Space

In today’s video we’ll give a demonstration of how to shrink tables that contain a lot of free space. As I say in the video, this is not something you should do regularly. It’s only necessary if you’ve done some drastic one-off maintenance, like a large data purge maybe.

There are a few articles this relates to.

The star of today’s video is Kellyn Pot’Vin-Gorman, who is returning to her Oracle roots, but on Azure. 🙂

Video : Returning REF CURSORs from PL/SQL : Functions, Procedures and Implicit Statement Results

Today’s video is a demonstration of returning REF CURSORs from PL/SQL using functions, procedures and implicit statement results.

I was motivated to do this after a conversation with my boss. He’s from a .NET and SQL Server background, and was a bit miffed about not being able to use a SELECT to pass out variable values from a procedure, like you can in T-SQL. So I piped up and said you can using Implicit Statement Results and another myth was busted. I guess most PL/SQL developers don’t use this, and I don’t either, but you should know it exists so you can be a smart arse when situations like this come up. 🙂

The video is based on these articles.

The star of today’s video is Bryn Llewellyn of PL/SQL fame, and more recently Yugabyte.
