I've worked with quite a few companies for which long-lived software assets remain critical to day-to-day operations, ranging from 20-year-old ERP systems to custom software products that first processed a transaction way back in the 1960s. The first and most obvious is that they are long on how to start, but short on how to finish.

This month and the next I’m going to cover the physical processing aspects of derived tables. That is, does SQL Server perform a substitution process whereby it converts the original nested code into one query that goes directly against the base tables? And if so, is there a way to instruct SQL Server to avoid this unnesting process?
