Database Corruption Challenge #9

Welcome to the ninth competition of ten in the Database Corruption Challenge. This week I have created a database and then corrupted one or more parts of that database, and your goal is to fix all of the corruption without losing any data. There is a total of 4 points available this week:

• One point for being the first person to provide a correct solution with no data loss. Won by Eduardo Rezende.
• One point to all who get a correct solution with no data loss.
• One point extra if you get the correct answer before any hints are given.
• One point extra if your solution is correct the first time you submit it to me. (check your work)

For information on scores take a look at the current scores page.

Corruption Challenge General Info

The challenge will be to download the corrupt or somehow damaged database and attempt to recover it. If you can recover it, please send me the steps you used to recover the database, along with some proof that the database has been recovered. The goal each week will be the following:

• Recover the database to your best ability.
• You need to be able to bring the database online and run queries against it.
• For any corruption that causes data loss, you need to figure out how to restore as much of the missing data with what you have been given.

When you come up with your solution, send me your result by email. Tell me what you did to fix the corruption, what you did to restore data (if that as needed), and include proof. The proof could be a screen shot, showing the solution, it could be a TSQL Script with the solution, or something else. I will validate and confirm if your result is correct. Depending on the number of people who send me results, this may take a while.

The first person who sends me a correct result will get their name posted on my blog as the winner of this weeks DataBase Corruption Challenge (DBCC). Others who send me a correct solution by the deadline will also get their name posted. Some of the first, accurate and unique solutions will be posted on the resulting blog post. If you don’t wish to have your name associated with your results, please ask to remain anonymous, and I will not use your name. Unless you specify otherwise, anything you send me may be used on the blog to tell the story of how to solve the corruption.
