Managing Statistics in SQL Server for DBAs (videos)

Want to learn more about managing statistics updates in SQL Server? Watch my free 27 minute presentation on managing statistics:

You can also watch 12 minutes of audience Q&A on statistics from when I presented this on a live Hangout on Air. Questions include:

  • Should I create single column statistics for non-leading key columns in an index?
  • What is asynchronous statistics update?
  • What are these statistics with “WA_sys” names?
  • I have a bunch of user created statistics and it’s blocking a release. It is safe to drop them?

Your presentation is greatly appreciated.


Would it make sense to do a FULLSCAN and update stats every night?


Great presentation! The situation with the apparently auto generated stats showing up as user created can easily be caused by pushing changes using tools such as red gate. I have found (and done…oops) this may times myself.
