Grant, if following tiny confusion can be explained?

Do DMV/Fs provide "Actual Execution Plan" or "Estimated Execution plan" specially Sys.DM_exec_Query_Plan?


Logically it should be "Actual Execution Plan" rather than "Estimated Execution plan"! But XML from DMV/Fs does not contain any <RunTimeInformation> tag! :-)

Thanks!

What you are pulling out of the cache is an estimated plan. The actual plans, with performance metrics based on the parameters passed are not stored.

IIRC that book first came out on amazon. Then it was brought in to simple-talk as a free gift.

All in all the 1000s of hors spent writing the book were supposed to bring in some $. So I guess this is why the 10$ for kindle edition.


P.S. The kindle link does not work.
