Looks like you have a temporary proc there. Kind of like a temp table, but it's a proc instead.

I am aware of that, the store procedure is created in the tempdb, but still does not answer the Question of how what and why is created or the Purpose of it.

thanks 🙂

If it's a temp proc, it was created on your system. We have no way of knowing what it is.

You could try scripting it to see the code.

From the name of it, I'd have to take a wild guess and think that it's something a DBA came up with the gather wait stats of some sort. If that's the case, I'd look at the scheduled jobs on the box to see if I can find it (you can also try querying the command column in msdb..sysjobsteps). I'd also look at the auto startup stored procedures to see if it's being kicked off from there.

As a last resort, I'd search through the syscomments table in all databases for something where text like '%wait_stats%'

Where are you seeing the exec command on it? In a trace?

Take a look in the trace for what commands were being run by the same SPID (if that's in the trace). That should tell you what proc or script is being run. If you have the text field in the trace (assuming that you do and that's where you got the exec command), it might even contain the create command for the temp proc. That's where I'd start.

Strictly as a pure guess -- Checking Books On Line for:

SQL Server, Wait Statistics Object at:

ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/udb9/html/cb7f917d-4291-4115-9b78-ee7692ebbb2d.htm

Can you associate any of the data returned with any of the items contained in the Wait Statistics Object?

If everything seems to be going well, you have obviously overlooked something.

Just a hint, "SSCertifiable" is a title for the number of posts, not the person. The username is right above that. Would be like addressing you as "Valued Member" (you'll see that right below your screen name). No big deal, but thought I'd mention it.

Traces are great for finding out "What the heck is going on in my database???"

You are probably running the Activity monitor which generates:

EXEC #am_generate_waitstats

entries in the Profiler after an executed query

GregoryF SSCertifiable Points: 6296 More actions · Answer 14

It is activity monitor, for the wait resources. However, does anyone know what goes into the SP #am_generate_waitstats?

I only get a couple of hits on Google for the SP and would really like to know how MSFT comes up with those values.
