Hi all,
I am attempting to assist a customer who has had some database corruption and doesn't have a good backup history.
As far as I can tell from the following CHECKDB result, there is no easy repair to be had because the corruption is in index 1 (= actual table data).
I just wanted to confirm that there were no easy options to resolve this type of corruption. At the moment I've advised that it doesn't look good and he needs to start considering reconstituting the data from alternate sources and the last known good backup.
Thanks in advance
