I have a table structured like this:
USERID char(3)
 LoginTime datetime
 LogoutTime datetime
 RowID int (unique)

I also have a stored procedure that successfully inserts a record when it is called. My question here is how can a retrieve the value of RowID after the record is inserted. I want to use that value to update the logout time when the user exits using another stored procedure. I have attached the beginning of that stored procedure.

You have several options for returning the value.
  • OUTPUT parameter
  • Return value
  • Resultset

BTW I strongly recommend using SCOPE_IDENTITY() instead of @@IDENTITY

Personally I like to return the entire inserted row as a result set.  Use an OUTPUT clause to save yourself an additional query.

insert into ACTIVITY (USERID,LOGINDAT)
OUTPUT INSERTED.UserID, INSERTED.LOGINDAT
values (@UserID ,GETDATE())

What would happen if the user logged in and then out and then back in again on the same day? It would not know which record to update. Given that ROWID is a unique identifier I was hoping I could return that value as that will always be unique.

I have used DML trigger statements (inserted table)

Yes, that makes sense but will it me give me access to the ROWID value that was created when the record was created or should a create another field where I am creating  my own unique value and using it in the insert command? The bottom line is I want something that will uniquely identify this row so I can update it when the user is on the way out.

Are you allowed to use triggers in your environment?

OUTPUT as described by Brian Crowe above is the best solution and to see what you are missing maybe please have a look here http://blog.sqlauthority.com/2007/03/25/sql-server-identity-vs-scope_identity-vs-ident_current-retrieve-last-inserted-identity-of-record/ where they are all well described:

"SELECT @@IDENTITY
 It returns the last IDENTITY value produced on a connection, regardless of the table that produced the value, and regardless of the scope of the statement that produced the value.
 @@IDENTITY will return the last identity value entered into a table in your current session. While @@IDENTITY is limited to the current session, it is not limited to the current scope. If you have a trigger on a table that causes an identity to be created in another table, you will get the identity that was created last, even if it was the trigger that created it."

And BTW - to audit those SQL login/logout events you could have a session table populated by your application on each user "login"/"logout"(X-disconnect)  action.

Dont go for trigger. They are difficult to manage as you not have control when they got executed.

I strongly suggests that you go with the Brains approach. Your requirement is very simple , for this trigger is not required.

CREATE PROCEDURE sp_SaveRecord 
( 
    @UserID char(3), 
    @new_id int OUTPUT 
) 
AS 

  DECLARE @rc int 

   select @rc = 0 

   BEGIN TRANSACTION SaveRecord 
         
   insert into ACTIVITY (USERID,LOGINDAT) values (@UserID ,GETDATE()) 
   
      if (@@ERROR <> 0)                 
          BEGIN 
             ROLLBACK TRANSACTION SaveRecord 
             select @rc = @@Error 
             Goto OnExit   
          END 
           
   select @new_id = SCOPE_IDENTITY() 
               
   COMMIT TRANSACTION SaveRecord 
           
  OnExit: 
  RETURN @rc 
         
GO

This solution correctly inserts a row into the ACTIVTY table. My question now is how do I get it to return the value of ROW_ID? ROW_ID is a unique identifier and I want to capture its value so that on the way out I can use it in a stored procedure that will update the logout time.

The value for which I am seeking is @USER_ID. This script works. Now I can use @USER_ID to update the logout time.

DECLARE @USER_ID INT
DECLARE @NEW_ID INT

exec sp_SaveRecord @UserID='SUP',@NEW_ID = @USER_ID OUTPUT

PRINT @NEW_ID
PRINT @USER_ID
