Well, I am making an application that allow users to create new users
with different rights and privileges. Each new user have an sql user
account in the database and are registered in a custom table.
So when I make a backup, the custom table will contains all the logins.
If after I remove some users with my application, the sql user will be
removed and the table will be updated. But, if I restore the backup,
the table will contain the deleted users and the sql accounts won't
exist so they won't be usable.
I don't know the clear password so I can't use sp_change_users_login or
sp_add_user.
So to backup/restore sql user account I tried the following thing
1) Make a copy of my users with
use test
go
SELECT * INTO x FROM master.dbo.syslogins
2) To restore them afterward
use master
go
exec sp_configure 'allow updates', 1
RECONFIGURE WITH OVERRIDE
go
insert syslogins select * from test.dbo.x
exec sp_configure 'allow updates', 0
RECONFIGURE WITH OVERRIDE
go
Thought it may have been a good idea but I get an "Update or insert of
view or function 'syslogins' failed because it contains a derived or
constant field." error.
Maybe I am looking on the wrong path...
