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).

A View Will Not Make Your Query Faster

Twice recently, one on a blog post, and one in a forum post, I’ve seen people state, unequivocally, without reservation or hint of a caveat, that, “Oh, just put that query into a view. It will run faster.”

To quote the kids these days…

Time for a rant.

But First…

When Simple Parameterization…Isn’t

I’m desperately working to finish up a new version of my book on Execution Plans. We’re close, so close. However, you do hit snags. Here’s one. My editor decided to change one of my queries. I used a local variable so that I got one set of behaviors. He used… Read more
