Changes to SQL Server 2012 Execution Plans
I’ve been working with execution plans quite a lot in SQL Server 2012. There are a number of changes, most of them associated with new or different functionality. I had not noticed anything really fundamental until recently. I’ve become a huge proponent of always checking the properties of the SELECT statement. There’s so much useful information in there about what’s happened with the plan generation in the optimizer (not low level stuff, but the big picture items) that you should always be checking it first as a fundamental part of your plan examinations.

Get Out The Vote
It’s actually kind of cool that SQL Rally voting for the pre-conference seminars and voting in the real(ish) world in the USA are coinciding. I’m in the running for the pre-con AND I’m volunteering for an actual election campaign for the first time ever.
