SQL Server performance tuning expert Erik Darling joins the podcast today to chat about how good queries can go bad and how bad queries can get better.
He also answers the question on everyone’s mind: if he was a database, what database would he be?

I double-checked my queries. Had I goofed in my sql? Nope. Next, I looked into if some of the data was in an inconsistent state.
What I found was worse than what I’d imagined. As a data person, it made me feel sad and icky.
