Column Groups

Patrick Jolliffe alerted the Oracle-L list to a problem that appears when you combine fixed length character columns (i.e. char() or nchar())  with column group statistics. The underlying cause of the problem is the “blank padding” semantics that Oracle uses by default to compare varchar2 with char, so I’ll start with a little demo of that. First some sample data:

The downloads and changelog are in the usual places.

So far I’ve only installed it on Windows 7, but I’ll no doubt be doing an install on OS X El Crapitan and Oracle Linux tonight. </p />

TABLE Operator with Locally Defined Types

postit-missed-itIn my OUG Ireland 2016 – Summary post I mentioned the Oren Nakdimon session called “Write Less (Code) with More (Oracle 12c New Features)”. One of the things he mentioned was the removal of restrictions associated with the use of the TABLE operator on local table types. If I had read about this or seen it before, it had certainly slipped my mind, so I made a note to write something about it and add a link to it from my PL/SQL new features article. So here it is.

Presenting “How Data Recovery Mechanisms Complicate Security, and What To Do About It” at #c16lv

Personally-identifiable information (PII) and classified information stored within an Oracle database is quite secure, as the capabilities of Oracle database ensure that it is accessible only by authenticated and authorized users.

But the definition of authentication and authorization can change, in a sense.authentication

In a production application, authentication means verifying that one is a valid application user and authorization means giving that application user the proper privileges to access and manipulate data.

Accelerating Oracle E-Business Suites upgrades

Taking backups during development, testing, or upgrades

The process of upgrading an Oracle E-Business Suites (EBS) system is one requiring dozens or hundreds of steps. Think of it like rock climbing. Each handhold or foothold is analogous to one of the steps in the upgrade.

What happens if you miss a handhold or foothold?

If you are close to the ground, then the fall isn’t dangerous. You dust yourself off, take a deep breath, and then you just start climbing again.

But what happens if you’re 25 or 35 feet off the ground? Or higher?

Another video fresh off the press.

If videos aren’t your thing, you can always read the article the video is based on.

The star of this video is Kevin Closson. Kevin’s a really nice guy and has a brain the size of a planet, but you know somewhere in the back of his mind he’s wondering what it would be like to hunt you down, kill you and mount your head above his fireplace. </p />

Playing around with JSON using the APEX_JSON package

hockey-149683_640We publish a number of XML web services from the database using the PL/SQL web toolkit, as described here. In more recent times we’ve had a number of requirements for JSON web services, so we did what most people probably do and Googled for “json pl/sql” and got a link to PL/JSON.

I know about the support for JSON in 12c, but we are not on 12c for these projects and that’s more about consuming JSON, rather than publishing it.
