Top 02 Ways to Repair MDF File

By Using DBCC CHECKDB Method

Is DBCC CHECKDB is a solution or not?

“There are situations when you use DBCC CHECKDB method but you are unable to retrieve your data. Many users and SQL server administrators have told me that these technique is useful but not every time. You cannot rely on this”

One of the major reasons for this is due to the fact that DBCC CHECKDB has been designed to tackle minimal MDF file corruption. So of your corruption level is higher than the mentioned level then there are good chances that it will be hard for the mentioned procedure to retrieve the given data as said.

“Found DBCC CHECKDB is not useful when I tried to repair MDF files. I found my data has been lost after running this command”

This is the most common experience which the user comes across while using the Database Console Commands. These commands can result even in more data loss. Microsoft suggests using backup for the restoration of the SQL database as a primary way.

Now the question is how to run DBCC CHECKDB?

You can run CHECKDB command on your corrupt SQL Server database using the following syntax:

DBCC CHECKDB [Required Database Name]

Now refer to the following cases.

Case I: When index ID is greater than 1, then drop it and recreate.

Case II: When index ID is equal to 0 or 1, then use the syntax like repair_rebuild, repair_fast, repair_allow_ data_loss

By Using SQL Server Management Studio

Follow the below steps to run SQL Server Management Studio.

Open Microsoft SQL Server Management Studio on your system.
Hit on the New Query tab.

EXEC sp_resetstatus [database name];
ALTER DATABASE [databasename] SET EMERGENCYM
DBCC CHECKDB ([databasename], REPAIR_ALLOW_DATA_LOSS)
ALTER DATABASE [databasename] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DBCC DATABASE ([databasename], REPAIR_ALLOW_DATA_LOSS)
