The word ‘statistics’ is awfully confusing in SQL Server
It can mean “statistics” themselves – little objects that describe the distribution of data in columns or indexes to help the optimizer.

I made y’all a SQL Server style Valentine’s day present: a new FREE online training course.
This week’s question is about a longstanding feature in SQL Server that sounds really cool: full-text search. If you’re learning performance tuning, how much time should you invest in researching and learning about full-text indexes?
You’re designing table partitioning, or you want to make a change to an existing partition function. It’s critical to understand the difference between how “left” and “right” partition functions behave, but the documentation is a bit confusing on this topic.
