sp_exec_whoisactive

I’ve posted a procedure that I wrote some time ago to make Adam Machanic’s sp_whoisactive easier to execute. It dumps the results of sp_whoisactive to a temporary table and selects the contents of that table. I’ve set EXEC sp_exec_whoisactive as one of my keyboard shortcuts in Management Studio. This makes it really easy to execute the proc repeatedly. If you aren’t using sp_whoisactive, I would advise stopping what you are doing and downloading it now. It is the most useful piece of code I’ve ever come across.

USE [master]
GO

--Drop procedure if it exists
IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[sp_exec_whoisactive]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].sp_exec_whoisactive
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

Adam is teaching an all-day pre-conference seminar entitled Better Performance Through Parallelism on Friday, April 25th. It is the day before SQL Saturday #291 Chicago. This is a great opportunity to get a day’s worth of training from the author of sp_whoisactive for a very reasonable price. You can get more information and register here.
