NEWBIE: How to use WorkstationID in TSQL?

Dear Experts,

Lowfatspread gave me a solution for identifying particular db users via their workstation name.  We are ready to implement it, but I'm afraid I don't know the actual name of the workstation field, as a "system" variable.  I have a working example of the USER system value:

select       @UserName = system_user ,...

If I wanted to pick up the workstation, what would I use? I assume it's something like "system_workstation"...

Thanks!

that gives you the host that is executing the query. If this is run on the server through the console or RDP it will give you the server. if you open up a connection to a server and run SELECT host_name() you will get the name of the machine from where you are running it.

This should be what you want. You can look host_name up in books online to see more about it.

to see more system functions, go to Books Online (BOL) and in the index search for "system functions"

I should have also said, the workstation system value will be provided by a connection string in this format:

connectionstring = "DSN=<dsn_name>;extended PROPERTIES=""workstationid=this_workstation""; "

I am a little confused here.. are you trying to ask sql for the workstationid/workstation name or are you trying to pass one of those to sql?

OK.  Enough non-backward-compatible posting!

I'm afraid host_id didn't work.  I'm getting:

  Invalid column name 'host_id'.

I'm trying to use a klduge here.  In the connection string, I'm saying:

PROPERTIES=""workstationid=this_workstation".

Then, using that connection, I make some change to the database, which causes a TRIGGER to fire.

Then, within a TRIGGER, I'm trying to pull the workstation.

So I guess I'm both passing the workstation to SQL (at connection), and then trying to receive it within the trigger.

SELECT host_id()

SELECT host_name()

those should work. just try them in SQL and look at the results.. The name is probably more useful to your trigger?

Sorry.  I think I didn't give enough explanation from the start.  (This all started from an EE exchange last week).

We have a browser-based app, which the user signs on to as "Bob".  This is not the UserID with which they signed on to their PC, nor is it the UserID used to connect to the db itself.  "Bob" is just how they are known within our app.

When the trigger is triggered, we want to use this kludge to get the string "Bob" inserted into an audit table.  We are trying to fake out SQL a little bit, by moving "Bob" where it might expect "WorkStation_3".  So we don't want the ACTUAL workstation.  We want the "workstation" that was passed in in the connection string:

connectionstring = "DSN=<dsn_name>;extended PROPERTIES=""workstationid=Bob""; "

I think what you're giving me is the how to get the ACTUAL workstation.  Based on the above connection string, how do I get "Bob"?

Sorry for causing so much confusion...  Always better to ask the question right the first time...

Yikes.  Very sorry.  Your very first answer was all we needed.  For anyone reading this, we had received only a general description of how to write the connection string.

Instead of:

 connectionstring = "DSN=<dsn_name>;extended PROPERTIES=""workstationid=this_workstation""; "

it should have been:

connectionstring = "DSN=<dsn_name>;extended PROPERTIES=""WorkStation ID=this_workstation""; "

With the property SPELLED CORRECTLY, then Mike Walsh's original answer works:

select host_name()
