Great article Gail. I'll be sure to forward this on to a DBA who I know has had a few corrupt database issues.

Good article Gail. Stuck it in my brief case. I just hope I never have to reference it to fix any of my DB's. BigGrin

fantastic article! easy to read, great examples, and right to the point. Now I am off to read Paul's article on what DBCC CHECKDB actually deletes when a REPAIR_ALLOW_DATALOSS is ran.

Nice article. I will definitely print this one out for lunchtime reading.

By the way, someone contacted me with a corrupt database a couple of years ago (they had NO backups) and I made the mistake of detaching it (yow!). This product saved my butt:

Recovery for SQL Server
http://officerecovery.com/mssql/index.htm

It can script out everything salvageable from a corrupt .mdf file and tells you what it did not get and why. When you need it, it is well worth the $499 price.

he Demo version is pretty cool in that it returns all the data with the primary keys but after the first few records puts DEMO in all the non-PK columns. With the demo you can at least see how much you are going to get back before you buy it.

Cheers.

Thanks for a very informative article Gail. It has helped me understand more fully the ways to tackle corruption, the very first one being backups, log and database!

Cheers
