SP_What is smarter than SP_Who2!
We’ve seen many DBAs scratch their head to find out who is running what in SQL Server. When a user complains about the database performance issue, the first thing DBAs do is run SP_Who or SP_Who2 to see what may be happening in SQL Server. Since the information returned is limited, DBAs use various scripts from other websites to add more misery to the problem. We recommend using SP_What instead of SP_Who or SP_Who2 for better productivity.
Start using SP_What instead of SP_Who2
So to find out what is happening in SQL Server, we would like to share the reason behind writing this best practice article. Last week one of our customers from (Lone Star State) asked us to help them with writing a lightweight smarter version of SP_Who2 which will simply show what (SP_What :-)) is happening in SQL Server but better than SP_Who2. We decided to call the new script as SP_What (What are you doing SQL Server?). We took the customers question “What is happening in SQL Server” and reviewed the output of both SP_Who and SP_Who2 and decided to include as many details as possible in SP_What that would help the customers answer what is happening in SQL Server. On our in-house servers when tested, we felt SP_What is smarter than SP_Who2.
