How to Find & Check Database Corruption in SQL Server?

In this section, we have discussed some methods to check for corruption. DBAs can use these methods to check SQL database for corruption.


DBA frequently use DBCC CHECKDB to find and repair damaged files. Other commands like DBCC CHECKCATALOG, DBCC CHECKALLOC, and DBCC CHECKTABLE are also included in DBCC.

Syntax – DBCC CHECKDB (database_name)

This command will review the storage, quality, consistency, and table metrics and present the results in a list.

Check for Database Alerts

Multiple forms of alerts that can notify about user misconduct or the occurrence of such acts that can harm databases can be set up by the database administrator.

If the database pages are corrupt, a feature called Memory Error Recovery for SQL Server 2012 or newer notifies the user of the error and conducts a cleaning operation.

With this feature, you can check database corruption in SQL servers and fix small corruption issues in SQL Databases.

Page Verify with CHECKSUM for Recovery

Every database has a Page Verify option configured in its property for recovery. Whether it is a read-only or read-write database is mentioned in such a feature. First, enable it by selecting Properties from the right-click menu while in the database.

Select Page Verify from the Recovery menu, then type CHECKSUM. Click OK after selecting the Target Recovery Time in Seconds.

The verification using the CHECKSUM option is enabled by default in newer SQL Server editions. The user can manually set it to CHECKSUM in the event that they have switched from an earlier version to a new version.

Now, the SQL Server will automatically apply the CHECKSUM whenever a new read or write operation is made on the database. Now, if a new read operation is attempted on a corrupt database, the user will receive error codes 823, 824, or 825.
