Video : SQL/XML (SQLX) : Generating XML using SQL in Oracle

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 />

ANSI Join Syntax in SQL Server

Another in a series of posts in response to Tim Ford's #EntryLevel Challenge.


Anyone new to SQL Server will sooner or later, and probably sooner, encounter exhortations to write joins in "ANSI join syntax". While the term is misleading and in fact incorrect, the practice of using the so-called "ANSI join syntax" contributes toward queries that are easier to understand and maintain. 

Clear Intentions

Following are two queries that produce the same result -- all possible combinations of product and subcategory names from the two tables listed in the FROM clause. (Such a result is termed a Cartesian product). Notice how I've written the joins in the respective FROM clauses.

Video : The MERGE Statement

After a what seems like an eternity of being ill and having a dodgy throat, followed quickly by a couple of conferences, I’ve finally got back on the horse and recorded another video.

I was explaining a specific aspect of the MERGE statement to one of my colleagues and while I was doing it I was thinking, “Have I done a video on MERGE yet?” Now I have.

The cameo for this video is Cary Millsap. If you watch the out-takes at the end you will see the level of respect and trust I have garnered in the community. The words confused and suspicious spring to mind! :)
