No, the system tables cannot be updated. Besides, syslogins is not a table, it's a view.

Thanks for the reply.

Even for some test purposes .Is there a way to change the updatedate in syslogins manually?

ALTER LOGIN bob DISABLE;

ALTER LOGIN bob ENABLE;

after you've disabled and re-enabled the login, the updatedate will be the moment the last event occurred( the enable)

You have to alter the login to change the date. The system tables cannot be directly updated.

sounds way too much like you are trying to falsify records for some reason.

Short of playing with the machine date (which will likely cause all sorts of problems with any auditing or security stuff), you can't.

What exactly are you trying to do?

I have a co-worker who wants to just update the login name instead of adding the new domain\login name for active directory groups that have been switched to a new domain. Is it better to drop and recreate the login when the domain changes or just alter login?

You will want to recreate the logins instead of renaming them, since Windows authenticated logins have a sid in the sys.server_principals that ties directly to the objectSid of the AD user or group.

Unfortunately, it will authenticate because of the SID history that is kept with the new windows login - The SID history is moved from the old login to the new so it will authenticate it correctly. So he wants to just update the name in syslogins. I'm totally opposed however, if I don't have a good reason, the powers that be will side with him as most have this "its good enough" approach. I'm more meticulous and would like to do it the correct way so that we have the New SID that belongs to the new domain login.

From what I read, even doing an Alter Login will not update to the new SID. So I think we need to Drop the old login from the old domain and add the new login from the new domain.
