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).

Precedence Goes to Query Store or Plan Guide?

While presenting at SQLDay in Wroclaw, Poland, on the Query Store, I was asked a pretty simple question, which takes precedence, the Query Store or a Plan Guide?

One of my favorite answers to questions is “I don’t know” because it gives me the opportunity to learn. Let’s figure this… Read more

A Moment For Reflection…

While this is a personal blog, I try to keep it focused on either technical topics or personal development and leadership related to technical topics. This post is a complete deviation from all of the above. Please, read it anyway.

I went to Auschwitz and Birkenau.

Words are failing me… Read more

On the Buckeye Blitz!

In just a few weeks I’ll be doing the Buckeye Blitz. That is, a tour of user groups in Ohio (aka, the Buckeye state, after a tree, not a sports team), one per day across a week. Here’s how it breaks down:

Cleveland: 6/13
Toledo: 6/14
Columbus: 6/15
Cincinnati:… Read more

Here’s what I’ve been up to.

First, based on your feedback (thanks) and conversations that I’ve had with members of the Board, I’m… Read more

Query Store, Forced Plans, and New Plans

I love questions. I recently received one about new plans in the Query Store (available in Azure SQL Database now and in SQL Server 2016 after June 1).

Let’s say you have selected a plan that you want to force. You set it up. Now, let’s say the plan ages… Read more

Use The Correct Data Type

Blog post #5 in support of Tim Ford’s (b|t) #iwanttohelp, #entrylevel. Read about it here.

Saying that you should use the correct data type seems like something that should be very straight forward. Unfortunately it’s very easy for things to get confusing. Let’s take a simple… Read more

Implicit Conversion and Performance

Letting SQL Server change data types automatically can seriously impact performance in a negative way. Because a calculation has to be run on each column, you can’t get an index seek. Instead, you’re forced to use a scan. I can demonstrate this pretty simply. Here’s a script that sets up… Read more

How to Convince the Boss to Send You to PASS Summit

August two years ago I originally posted, Make the PASS Summit Work for Your Employer. After conversations at several SQL Saturdays over the last couple of months, I decided to refresh and update that original content and post it again.

I keep hearing how the job market has changed. That… Read more
