Pleasure.

There’s an introductory series on Indexing on SQLServerCentral that you may find useful. http://www.sqlservercentral.com/articles/Indexing/68439/

I’ve been using SQL Server for about 5 years, and have found that every resource I’ve encountered on indexing always sort of glosses over how to actually do it. I was still left asking “but what are the rules?”. Your 24 hours of Pass talk on Effective Indexing was the first time I took a page of notes that actually summarised some key rules – technicques and rules of thumb for equalities vs inequalities, left based sets, group by and order by etc. Thanks for laying out some really useful indexing guidlines!
