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).

Note, in this… Read more

Don’t You Know Who I Am?

I’m happy to say that for most of you out there, the answer to this question is “no.” That’s as it should be. I’m not anyone all that special. I present technical sessions at various events from local user group meetings to SQL Saturday’s to international events like the PASS… Read more

Which SELECT * Is Better?

The short answer is, of course, none of them, but testing is the only way to be sure.

I was asked, what happens when you run ‘SELECT *’ against a clustered index, a non-clustered index, and a columnstore index. The answer is somewhat dependent on whether or not you have… Read more
