Question

Hi I have a simple question. But it lead to another question. I want to delete the query plan for a stor proc i ran. So I ran the proc using

exec dbo.uspNameOfProc

and then checked the plan chace using the query

SELECT [text], cp.size_in_bytes, plan_handle
FROM sys.dm_exec_cached_plans AS cp CROSS APPLY 
     sys.dm_exec_sql_text(plan_handle)
where [text] like '%uspNameOfProc%'

what else am i missing?

Answer 1

RUN exec dbo.uspNameOfProc Then Run sp_who3 Find out which spid it is running under.

Then run USE master;
GO
SELECT * FROM sys.dm_exec_requests
WHERE session_id = YourSPID;
GO

This will get you the Plan handle. To see the execution plan run.

USE master;
GO
SELECT * FROM sys.dm_exec_query_plan (YourPlanHandleID);
GO

Then if you wish to clear the plan from cache use this.

DBCC FREEPROCCACHE (YourPlanHandleID);
GO

Hope that helps.
UPDATE***
Make sure perform these operations on separate query windows so as to not alter the execution plan.
