I’ve been asked if I can get a listing of users and the last time that they have accessed the database through an application. I do not want to use sql profiler,I am trying to create a trigger to accomplish this. The sysprocess system table seems to store the fields that I need.I used sp_configure and set allow update to 1. I received the error Create trigger permissions denied on object ‘systemtable’ , database ‘master’, owner ‘dbo’. Does anyone know a work around, or have any other suggestions on how to accomplish this?

I don't think you can trigger sysprocesses as this is a fake table. It is a memory structure that only materialized when queried:

select

objectproperty(object_id('sysprocesses'),'Tableisfake')

-----------

1

(1 row(s) affected)

What about a job doing this

what will this select statement do?

select

objectproperty(object_id('sysprocesses'),'Tableisfake')

it means you can't put a trigger on that table (on any system table for that matter).

You'll have to do snapshots of the table an extract the data from there.

Take a look at my script over here,

It returns 1 = TRUE. So sysprocesses is a fake table. You can read about the OBJECTPROPERTY thing in BOL. It comes in handy in many situations.

I tried the script capture_spwhoScript. I added my database to the script, I tried creating my server as a linked server and I received an error. You cannot create a local sql server as a linked server. Am I doing something wrong?

If you already have the server setup as a Remote Server then you'll need to give the linked server a different name.

EG If you have a server called ServerA. It is most likely setup as a remote server called ServerA. so you'll need to give it a different name as a linked server.

sp_addlinkedserver 'ServerA2', '', 'SQLOLEDB', 'ServerA'

Hi

I got over the linked server error. server name stageserver, linked server stageserver1, database name production. I replaced the 3 database names in the script to production and the server name in the script to my linked server name of stageserver1. Is there anything else in the script that I need to modify? When the job runs it gets the error listed below.

Executed as user: AD-MEA\SQLSRVC. OLE DB provider 'SQLOLEDB' reported an error. [SQLSTATE 42000] (Error 7399) [SQLSTATE 01000] (Error 7312) OLE DB error trace [OLE/DB Provider 'SQLOLEDB' IDBInitialize::Initialize returned 0x80004005: ]. [SQLSTATE 01000] (Error 7300). The step failed.

Thanks for all of your help

sa is already listed as the owner.

Phillip,

When I executer EXEC dbo.usp_CaptureActivity from the query analyzer it works fine. When I run it as a job with sa as the owner I get an error.

Question2

I was looking at the rolls in the tblActivitylog and it can become huge over time. What the client wants is to be able to run a query and only see the last time the login user accessed the system. They have 255 users and only want the login listed once. If the user logs in for the first time insert the row, after their login is already in the system they only want to update the lastUpdate field with the new date/time. Really they only care about the login and lastUpdate field, they don't care what they were doing. How do I accomplish this with a trigger on the tblActivitylog table?

Thanks again,

MS_CRB
