select @@version

union

select current_user+' '+'as'+' ' +system_user

something like this?

to add to what Henrico gave you, here's a collection of some of the available functions for that kind of information:

i logged in as sa, then my windows domain, and then a SQL login i created.

select

user_name() AS [user_name],

suser_name() AS [suser_name],

current_user AS [current_user],

system_user AS [system_user],

session_user AS [session_user],

user AS

/*

user_name suser_name current_user system_user session_user user

dbo sa dbo sa dbo dbo

dbo DOMAIN\lowell dbo DOMAIN\lowell dbo dbo

guest bob guest bob guest guest

*/

Hi Lowell,

I know this functions and i will not meet my requirement by this function.

Let me clear you once again the steps i followed

1.I am logging to my Laptop /PC using username 'xyz'

2.then i will open the SQL server Management Studio

3.it will ask for aunthentication and i ll select Sql server aunthentication and enter the

loginname:sa and pwd:sa123

4.if i execute select @@SERVERNAME it will display 'abc\sql2005'

Now what i need is an query to fetch the Laptop/PC logine ie;'xyz' using the server name

ie;'abc\sql2005'

please do the favour

Thanks and Regards

select system_user

will provide you the exact user who logged into the machine.

ahh i see what you are after;

if you login to SQL with SQL authentication, your windows login information is not used, and would not be available i think;

if you login to SQL with Windows Authentication, then the system_user function will get what you were after;

you could try going to xp_cmdshell and running the "whoami" command, which would return domain\login, but i believe it will return the Service Account, which might be Stestem or Network, or maybe a custom account that might be running the service, and notwho happens to be logged in;

no way to get the logged in user than i can think of so far;

xp_cmdshell gave me this as a result of whoami:

create table #Results (

LinesFromCmd varchar(1000))

insert into #Results (LinesFromCmd)

exec master..xp_cmdshell 'whoami'

select * from #Results

--nt authorityetwork service

drop table #Results

maybe you could read the registry for current user....but the better thing to do is simply pass the credentials from your application that is connecting to SQL;

you probably should fill in the gaps and tell us what you are trying to accomplish; there's probably a better or different way to do it than you are thinking.

also another thread looking for the same issue, and everyone agreeing it's not possible withought jumping to poweshell or wmi, but with a better explanation than mine:
