Hi I have 100 or so users in a database but I need them all to have a server login also
I was thinking of doing this in a cursor and have come up with
Declare @username varchar(50);
declare updateServerroles cursor for
SELECT name FROM sysusers where name = 'TEST\user'
open updateServerroles
fetch next from updateServerroles
into @username
While @@FETCH_STATUS = 0
begin
CREATE LOGIN @username FROM WINDOWS WITH DEFAULT_DATABASE=[***********], DEFAULT_LANGUAGE=[us_english]
exec sp_addrolemember db_datareader, @username
exec sp_addrolemember db_datawriter, @username
end
close updateServerroles
DEALLOCATE updateServerroles
but the 'create login' will not work. Please can someone give me some advise
thanks in advance
Paul

try this in your cursor code

DECLARE @SQL NVARCHAR(4000);

While

begin

SET NOCOUNT ON

SET @SQL = 'CREATE LOGIN ' + @username + ' WITH PASSWORD = ''12345'', DEFAULT_DATABASE=[dbname], DEFAULT_LANGUAGE=[British], CHECK_EXPIRATION=OFF, CHECK_POLICY=ON';

EXECUTE(@SQL);

exec sp_addrolemember db_datareader, @username ;

exec sp_addrolemember db_datawriter, @username ;

end

Hi, very true!

Cursors aren’t all bad. In fact, they can make some database problems a lot easier to solve. But take a step back and really examine the problem. There is a chance that you can use a more efficient set-based approach to solve your problem.

Cursors VS Loops is an argument that will never be won. a cursor can be faster than a while loop if written correctly. This is one place where a loop or cursor is appropriate as each user needs to be run and is by its nature an RBAR process.

I, too, don't have a problem with a cursor per se here; it could be done w/o one, but it's not a big deal for such a limited number of rows.

You should get away from "sysusers", which is also obsolete, but again that's not a killer issue either.

But, the cursor should be optimized with FAST_FORWARD:

...

declare updateServerroles cursor fast_foward for SELECT name FROM sysusers where name = 'TEST\user'

...

Edit: Corrected typo.
