> It would be useful to have a tool for dumping the data in a corrupted
> database. This could start out as a custom tool. After we debug the tool and
> get some experience with it, we can consider promoting it to be a (possibly
> undocumented) optional tool which we ship with the product. I think the tool
> should have the following behavior:
> 1) The tool should not subvert the security of the corrupted database. If the
> corrupted database is password-protected, then you would need to present its
> DBO's credentials in order to use the tool. Naturally, an encryption key
> would have to be presented in order to decode an encrypted database.
> 2) The tool should not stop reading a table when it hits a corrupt record.
> Instead, the tool should soldier on and collect a list of warnings on bad
> records.
> Such a tool would be useful in situations where some part of a heap table is
> corrupt but the following heap conglomerates are intact:
> i) SYSSCHEMAS
> ii) SYSTABLES
> iii) SYSCONGLOMERATES
> iv) SYSCOLUMNS
> v) property conglomerate
> Such a tool would be useful for some situations where data can't be dumped
> even after you delete the log files in order to short-circuit recovery.
