Take the 2-minute tour ×  Does Adam Machanic's sp_WhoIsActive
return the actual query plan or the estimated plan when run with
@get_plans=1 ?  share|improve this question add comment  1
Answer  up vote 8 down vote accepted  The tool grabs the plan
that is being run at that time. From an email response from
Adam:  "Actual plan" usually refers to the query plan that has
the actual row counts, number of executions of each iterator,
etc. Who is Active cannot return that version of the plan. But
the plan it returns is indeed the "actual" plan that's running
at the time -- in other words, the plan will not be recompiled
into some other plan by the time Who is Active can get it.
