Simple Steps to Repair or Fix Index Corruption in SQL Server

In this blog, you will find the complete detail about the SQL Server Index Corruption issue and the multiple ways to Fix Index Corruption in SQL Server

Microsoft SQL Server is popularly used by many small and big industries to preserve their data in a synchronized manner.

SQL Server is the best option as it let users store and access data in a vast amount within a safe mode. It always gives the priority to the data security hence never harms its credibility.

SQL server stores data in MDF(as a primary file) and NDF (as a secondary file), which are quite prone to corruption as per the studies. If there is an error issued in MDF then you cannot access NDF.

Also, SQL Server generates the LDF (a log file) the transactions log file, it contains the history of both fully or partially committed transactions to the database.

There are many types and level of corruptions found in SQL Server, among which corruption in the clustered index is very basic. This corruption makes data stored in MDF and NDF files inaccessible.

Best solutions to Repair SQL Server Index Corruption

I have tried to mention some suitable solutions to fix index corruption in SQL Server

1. Use DBBCC Command
2. Restoring the Backup
3. SQL Database Repair Software

It is clear that SQL Server database includes only one clustered index. So, it is quite recommended for you to create a new non-clustered index on the table. If you are looking forward to alter or change the way in which the SQL database is clustered, then it is needed to first drop the existing clustered index before you think to create a new one.

Solution 1:- Using DBCC Command to fix SQL Server clustered index corruption

Database console commands are used to fix the issue. It undergoes scanning of the logical and physical integrity of the clustered index by comparing it with its actual value. Use the console command in the following manner:

DBCC CHECKDB (CorruptDB) With No_InfoMsgs, All_ErrorMsgs,
TableResults;
GO

This will give a list of errors and automatically repairs them by this single command. By this, you will recreate an existing file as a new one. Hence the index corruption of files will get fixed.

Solution 2:- Restoring the Backup

If rebuild of the database is not an option which is described in above point, then anyone can restore an old or existing database. Hence restoring the backup is the most simpler and easiest way to repair SQL Server Index corruption.

NOTE:- This process will remove or delete any changes made to the records after the backup was taken.

Solution3:- SQL Database Repair Software

The alternate way to fix SQL Server clustered index corruption is by using any third party tool that is advanced enough to handle the repairing of corrupt or damaged SQL Server Database (MDF) much more safely and securely. The best part of using SQL Recovery Software is that it makes the process much quicker and eliminates the manual interventions.

Also, it is highly opted to repair SQL Server index corruption when you are lacking with the database backup.
