The Scary DBA

I have twenty+ years experience in IT. That time was spent in technical support, development and database administration. I work forRed Gate Software as a Product Evangelist. I write articles for publication at SQL Server Central, Simple-Talk, PASS Book Reviews and SQL Server Standard. I have published two books, ”Understanding SQL Server Execution Plans” and “SQL Server 2008 Query Performance Tuning Distilled.” I’m one of the founding officers of the Southern New England SQL Server Users Group and its current president. I also work on part-time, short-term, off-site consulting contracts. In 2009 and 2010 I was awarded as a Microsoft SQL Server MVP. In the past I’ve been called rough, intimidating and scary. To which I usually reply, “Good.” You can contact me through grant -at- scarydba dot kom (unobfuscate as necessary).

PASS Board Update: May 2015

I’ve had a busy month on the Board.

You may have seen some tweets going by about our compliance with international laws regarding SPAM. This has been something of an education, so anything I say wrong below, it’s because I’m wrong, but not malevolent (at least in regards to this… Read more

Database Engine Tuning Advisor

I would love to see the Database Engine Tuning Advisor (DTA) pulled from the product. Completely. Heck, I feel bad that I included a chapter on it in my query tuning book (all updated for SQL Server 2014 by the way). Let me tell you why we need to pull… Read more

Book Review: Connected

I heard about Connected from a show on NPR (Yes, I listen to NPR, why do people keep saying that?). It was right after another segment talking about how positivity affects your mood and your ability to think and act in a clear fashion. I’ve long been a believer in… Read more

Come to Us or We’ll Come to You

No, that’s not a threat. It’s an offer to help out.

I Am Grateful For…

I’m almost done reading the book Connected (will be by the time this is published). It’s fascinating although, at least so far, little in the way of suggestions for how to take advantage of this information. That however doesn’t change my plans around working on positive thoughts and emotions as… Read more

Is Performance Better With LEFT JOIN or RIGHT JOIN?

I tend to write my queries using LEFT JOIN. Why? Because logically I see it in my head like this:

Give me all the rows from this table and only those rows that match from the other table.

But, wouldn’t this logic work just as well:

Give me only the…

Effects of Persisted Columns on Performance

I live for questions. And my favorite questions are the ones where I’m not completely sure of the answer. Those are the questions that make me stop presenting in order to take a note so I can try to answer the question later, usually in a blog post. Guess where… Read more

Speaker of the Month: May 2015

I finally got out to some community events last month and got to see a bunch of great speakers. Not that you don’t see great speakers at paid events, you do. It’s just that they’re usually professional speakers and I want to encourage others when I can.

The Speaker of… Read more
