Baton Rouge SQL Server User Group

I will be speaking at the February Baton Rouge SQL Server User Group meeting on Wednesday the 8th. The session will be an continuation of Execution Plan Basics that I shared last year and at 2 SQL Saturday events plus Houston Tech Fest in 2010. This one is called Execution Plan: Beyond The Basics. The topics include Digging deeper into Loops, Missing Indexes in Query Plans, WHERE clause and LEFT JOIN, TempDB usage, SQL Server 2012 improvements to Query Plan and Tools like SQLSentry’s Plan Explorer, Database Tuning Advisor and SP_WhoIsActive from Adam Mahanic.

I am hoping this session gets pick by some SQL Saturday events in the future, first at Houston with Nancy Hide Wilson and Jonathon Gardner. Still looking at Pensacola and waiting for John Sterret and gang in West Virginia to add one to the schedule. Really would like to do a half day execution plan session, that would be nice.
