Open in new window

will return the name of the logged on user in SSMS.  But I don't understand the purpose of this?  Are you doing this through code, and if so can't you pass the environment variable for username through that way?

SELECT SYSTEM_USER will tell you the login in use.
SELECT CURRENT_USER will tell you the user.

These aren't necessarily the same thing. It depends on the user-login mapping for the particular database.

SQL Server is a multi user RDBMS so in many situations, many users could be connected. However if it is known to be a single user situation where it is just an app with SQL Server these might help:

2008 and forward:
SELECT CURRENT_USER;      this will return the current user

SELECT SYSTEM_USER;         gets users currently executing the script

You can use  normal TSQL
UPDATE sometablename SET somefield=whatever
WHERE somecondition is true

with that information to do what you want I guess

Without a more clear explanation, help can't be further provided.

What are you auditing?  Users in SSMS?  Are you intending for this to be a trigger or something?

      [SQL] [nvarchar](2000) NULL,
      [EntryDateTime] [datetime] NULL CONSTRAINT [EntryDateTime]  DEFAULT (getdate()),
      [User] [nvarchar](2000) NULL   CONSTRAINT   DEFAULT ((SYSTEM_USER)),

Any suggestions on this ?

Are you getting an error? You do have an extra comma that I think shouldn't be there after SYSTEM_USER))
