Encryption and the Performance DMOs
Ever wonder what you can see in the performance oriented DMOs when stored procedures were encrypted? Me neither. But, I did get that question during my DMO presentation at the PASS Summit. I did not have an answer. I did get an answer from Johan Bijnens (twitter) from the audience, which I repeated without entirely knowing what I was saying.
