Recover a corrupted MS SQL database

I have not tried this, use with caution.

There is a manual solution to fix this problem, but you need to have Microsoft SQL Server Management Studio for that. If you have it, you need to follow the steps given below:

• Open Microsoft SQL Server Management Studio on your system.
• Now click on New Query button.
• A new query page will be opened. Write the SQL scripts (shown below) on the page:

                    EXEC sp_resetstatus [YourDatabase]; 
                    ALTER DATABASE [YourDatabase] SET EMERGENCY  
                    DBCC checkdb ([YourDatabase]) 
                    ALTER DATABASE [YourDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE 
                    DBCC DATABASE ([YourDatabase], REPAIR_ALLOW_DATA_LOSS) 
                    ALTER DATABASE [YourDatabase] SET MULTI_USER 

• Now click on Execute.
