Dave Ballantyne

Dave is a freelance SQL Server database architect / designer / developer / consultant and lives near London, England.  He takes a keen interest in all things SQL and data related and is never happier than picking apart a poorly executing query.  He has also created an open sourced add-in for SQL Server data tools (SSDT) called "TSQL Smells".  This detects and reports on 'suspect'  code within a project and can be found at http://tsqlsmellsssdt.codeplex.com . Outside of work he is husband, father of 3 and exasperated archer.

This session will be a deep dive into the optimizers' internals and not for the faint of heart.

At the heart of SQL Server is the cost based optimizer. This is driven by estimates and they in turn are driven by statistics. This will be a deep dive into how the optimizer makes its decisions to give you a plan, the things that can go wrong.
The query optimizer is at the heart of SQL Server. Much of the its' internal workings are hidden from the user, but can be revealed by using a selection of undocumented trace flags. This session will be a deep dive into the these internals.
