Hi John, Good question. You certainly could use dynamic SQL to create temporary tables each time, and this would prevent caching as I describe in the follow-up post to this one at...

Martin, Connecting via the DAC to see sys.sysrscols (or sys.sysrowsetcolumns in 2005) I have noticed that issuing a CHECKPOINT seems to cause the in-memory counters to be flushed to persistent storage,...
