Microsoft SQL database corruption may happen due to various reasons including human error and various external factors. Corruption renders SQL database inaccessible, which puts the data and business at risk. This step-by-step guidance outlines the common SQL database corruption situations and how to repair the corrupt database. The first solution includes restoring the database from backup, and the second solution includes repairing it by using the DBCC CHECKDB built-in utility.
To successfully recovery SQL Server database from a failure, the set of SQL Server backups need to restore in a logically correct and meaningful sequence. The restoration process supports restoring data from backup sets of a whole database, a data ?le, or even a data page.
Microsoft provides a DBCC utility to keep consistency of the database by attempting to repair the corrupt pages or data. There are also powerful third-party applications that can be used if all other options including DBCC CHECKDB have been utilized to no avail.
