Speaking in St. Louis on June 12th

I'll be speaking to the St. Louis SQL Server Users Group on the afternoon of June 12th at the Microsoft offices from 1PM until 4PM.  I'll be doing two presentations back to back.  The first is What I Wish Developers Knew about SQL Server.  The second is Understanding the Procedure Cache: Writing Efficient Reusable Queries.  The two presentations flow very well together.  The second really builds on the concepts introduced in the first.  The event was organized by Kathi Kellenberger through the PASS Star Program.  Thanks Kathi!
