MS SQL Server is one of the most popular databases. It has an advanced internal structure and offers great reliability. That is why most organizations use the SQL Server database to save all crucial business data. However, MS SQL Server is vulnerable to different threats like database corruption and errors. The SQL server databases file corruption makes the database objects inaccessible. There are various factors that can make the SQL server database file corrupt. The common causes of MDF file corruption are listed here:

  • Bugs in SQL server itself
  • Abrupt system shutdown while the database is opened
  • Changes in SQL account
  • Virus infection
  • Upgrading SQL Server from previous versions to newer one also, at times, results in the corruption of the database.

Solution - DBCC CHECKDB

The command DBCC CHECKDB can be used to check the inconsistencies of the database and repair it. If your database is corrupt, it could be a good option to repair the database. You can use the command to repair specific objects or components instead of the whole database.

To run the command, you can follow this:

DBCC CHECKDB (database_name)
