This is my third in a series of checklists that I am putting together for a new book designed for DBAs to help audit their SQL Server instances. Previously I blogged about my SQL Server Hardware Checklist and my SQL Server Operating System Checklist. The goal of this checklist… Read more
We had an unexpected switch last weekend. My boss decided that we were ready to move from the Stack Exchange (SE) to an alternative, OSQA.net, without informing any of the people that work on the site. Needless to say this wasn’t a seamless transition, but it was fairly smooth. The… Read more
The following queries look extremely innocent. However, they are all application killers once the target table grows to more than a couple thousand rows:
Select Count(*) From Person_Data Where Upper(Name_Last) = ‘SMITH’
Select Avg(Collar_Size) From Person_Data Where dbo.MyFunc(Person_Data_ID) > 500

Wow, how moving house interrupts life. I can appreciate we have not had to move about more frequently! Background: Starting at the beginning of May, a month prior to moving, my sage wife Victoria insisted we start the packing… Read more
It’s been a busy month for me for PASS activities. I spent almost the entire week last week on PASS related items and probably 60+ hours for the month:
- Reviewing the annual budget
- A call on SQLSaturday to work on plans for 2011
- Tons of time on the Spring Event
Thanks to the outstanding efforts of Tim Edwards (twitter | blog), our fearless leader, and the rest of the crew, the PASS Performance Virtual Chapter is rolling and we've started to make ourselves known through various on-line media. It gives me great pleasure to pass on that we're having… Read more

Overall, the main methods of storing data since the 1960’s, magnetic tape and hard disks, have improved… Read more
This is a little bit off topic for me but on Friday I was asked to look at a DB2 instance and sort out some issues with the CPU maxing out. Make no mistake I’m no DB2 expert, but I have done some small pieces of work on it previously,… Read more
One of my back burner projects is to setup a local user group. I'm delighted to now say that this is up and running. Over the next few months, I hope to provide some great quality sessions and also provide some ‘virgin’ speakers, myself included, with an environment to practice. If… Read more
“...And the world is filled with people who can't go to high school, never mind college, and who certainly can't spend their time focused on whether or not they get the good parking space at work.
And so, the obligation: don't settle.
To have all these advantages, all this momentum,…
I’m not a big networking person. I know that it’s good for my career, but I’ve been lucky enough to get myself fairly well known, my picture is on daily emails from SQLServerCentral, and so a lot of people know of me. As a result, I don’t have to… Read more
OK, are you ready to start the MDX journey. In MDX Puzzle #1 posting I presented you with the challenge of writing an MDX query based on the requirements that I outlined in that posting. In this solution and all subsequent solutions I will walk you through the process of… Read more

“Content is king” is the golden rule of the SEO. The semantic web is all about data. Any web or traditional application has no value without data. Few people have discussed the future of Data, Pat Halland being one of the most prolific ones. Data is and will be everything: Read more
I’ve had the opportunity this week to take class with Don Jones (blog | twitter), PowerShell guru and author of PowerShell 2.0 TFM (makes me laugh, each and every time). I’m not even going to attempt to try to teach you some of the amazing information Don has… Read more
Whilst perusing the forums over at SQL Server Central today I stumbled across an interesting question regarding how to identify how much memory is being used by SQL Server on a per database level.
As you know SQL Server stores database data and index pages in memory in an area… Read more
It has been awhile since my last post mainly because I was on a working vacation in northern New England with limited internet access, but also because I wasn’t sure what I wanted to write about.
You may be wondering how a technical professional can have a working… Read more
