问题
So I'm trying to manually update hash for one user. I tried updating view, as tables are not visible.
I tried starting in single user mode, changing "sp_configure 'Allow updates',1", and so on, with no luck.
Is there any way. I don't know passwords, just hashes, as updating from 2000 SP4 to 2008 R2 failed, and I need to have credentials on 2008 R2, just like on old 2000.
回答1:
The sp_Configure 'Allow Updates' setting has had no effect since SQL Server 2005, it will still "work" but it won't do anything.
I believe that if you really must make these changes, you can do so by connecting through the DAC (Dedicated Administrator Connection) while the instance is in single user mode, but be careful what you change :)

If you're running SQL Server 2000 or earlier you can run:
RECONFIGURE WITH OVERRIDE
