Its been a fair few years since I started blogging on SQLBlogCasts and the time has now come to find a new home.
On the weekend of the 9th March 2013, the second SQL Saturday in the UK occurred. A massive thank you must go to all the sponsors of the event, FusionIO, Confio, Nexus, Purple Frog, Redgate, Idera and Big Bang Data.

Late in December, one the long awaited portions of functionality inside SSDT was released to an eager public, that being unit testing. There has been a lot of noise generated about sql unit testing as a concept recently and hopefully you have decided that that is now the way to… Read more
As I'm sure I must have mentioned in the past, I’m presently involved in a large ALM project at a client. Part of this project is using Sql Server Data Tools (SSDT) to aid the developer experience and to establish the schema under source control as “The Truth”.

Whilst working at a client site, I hit upon one of those issues that you are not sure if that this is something entirely new or a bug or a gap in your knowledge.
The client had a large query that needed optimizing. The query itself looked pretty good, no… Read more
Over the past few years, Ive had it on my to do list to write and deliver and full-scale SQLServer training course and not just an hour long bite size session at user groups and conferences. To me, SQLServer development is not just knowing and remembering the syntax of commands. … Read more

Deadlocks can be a really tricky thing to track down the root cause of. There are lots of articles on the subject of tracking down deadlocks, but seldom do I find that in a production system that the cause is as straightforward. That being said, deadlocks are always caused by… Read more
OK, so that is quite a contradictory title, but unfortunately it is true. There is a common misconception that the query with the highest percentage relative to batch is the worst performing. Simply put, it is a lie, or more accurately we dont understand what these figures mean.
