Hello!
I was wondering whether someone could help me with creating a loop to iterate through a table (sys.syslogins) and
change the default databases to a different database for all sql logins. If successful, the users should be directed to the newly
selected database at logon. We have nearly 150 users that login to the server.
So far, I have a script that gives me a list of all logins and databases, as shown below:
select name,
loginname,
dbname as DefaultDB,
DATABASEPROPERTYEX(dbname, 'Status') as DBStatus
from sys.syslogins
order by DBstatus
I thank you very much in advance!
MK

You should look up ALTER LOGIN in BOL.

use msdb

select 'ALTER LOGIN [' + name + '] WITH DEFAULT_DATABASE = YOUR_DB; ' from sys.syslogins where language = 'us_english'

and name not like 'NT %' and name <> 'sa' and name not like '##%'

and name not like 'NT %' and name <> 'sa' and name not like '##%'

Starting with SQL Server 2005 you should really use sys.server_principals for this instead of sys.syslogins which is a compatibility view for SQL Server 2000 compatibility.
