MS SQL forms the base of the SQL Server Database management. Microsoft developed SQL as a relational database to store and retrieve data.

SQL saves files in two parts: MDF or Primary and NDF or Secondary. When the Index corruption in SQL occurs, then we cannot access any of these files. This can be caused by many reasons like bugs in SQL Server, abrupt system shutdowns, upgrading of SQL Server version. This corruption causes data safety and security issues as many entries are displayed as missing.

You can start with this database consort command. It checks the internal structure. This command examines all the records for the possible changes in data integrity. It is used as a primary method to fix Database Corruption in SQL Server. Use it with the following syntax:
DBCC CHECKDB (databasename) with NO_INFOMSGS, All_ErrorMsgs, TableResults;
Once you enter this, all the errors in your system get shown to you. Also, it suggests one of the following methods, to repair MS SQL Server.
- REPAIR_REBUILD- This method fixes minor issues and recovers missing rows in the non-clustered Index. It recreates a complete index after comparing the present structure with an old one. But the major issue with this method is that it takes a long time.
- REPAIR_ALLOW_DATA_LOSS- We suggest to use this method if there are too many allocation errors. In case the REPAIR_REBUILD has failed to recover records, then only use this method. That means corruption is of higher level and with the implementation of this method data loss is quite possible.
