How can I display the execution plan for a stored procedure?

SET SHOWPLAN_ALL ON
GO

-- FMTONLY will not exec stored proc
SET FMTONLY ON
GO

exec yourproc
GO

SET FMTONLY OFF
GO

SET SHOWPLAN_ALL OFF
GO

Select the storedprocedure name (just type it in a query window), right click, and choose the 'Display Estimated Execution Plan' button in the toolbar of SQl Server Mgmt Studio. Note that you don't have to have the stored procedure code open. Just the procedure name has to be selected.

The plan for the stored procedure from with in the called procedures will also be displayed in graphical form.
