MS SQL Server provides the DBCC statements that are used to check and fix the databases for physical and logical consistency. There are various types of DBCC statements that you can use for the any particular purpose. However, at times these commands are not able to perform. The reason behind is that these database may have corrupted because of various reasons such as virus infections, hardware issues, human errors, etc. In such cases, you should use a third-party MDF repair
software to repair SQL database.
Consider a scenario wherein you are working on an SQL Server 2000 database. In this, you use the DBCC CHECKTABLE command on a particular table to make it more scalable and achieve parallelism. However, the command failed to execute. An error message is displayed, that is:
“CHECKTABLE terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.”
The root cause of this error message is that the internal query that was used by DBCC failed to deliver the desired result. It may be possible that the tempdb database has gone out of space or there is an inconsistent system table.
To resolve this error message, you should perform the following methods, preferably in the given order:
Check for hardware issues
: You should run hardware diagnostics and check whether the issue is raised because of any malfunctioning hardware component. You can also check the error logs, or swap the hardware components to zero in on the source of the issue. Also, you can also consider reformatting the disks and reinstalling the operating system.
Restore from backup
: You should check if the backup is updated and clean. If yes, then you should restore the database from its backup.
Run DBCC CHECKDB
: You should run DBCC CHECKDB first without a repair clause, and then with the repair clause after determining the extent of corruption.
The aforementioned methods will be able to resolve the error message and you can access the database properly. However, if it is not so then you should use a third-party SQL data recovery
software to repair the corrupted database. Such read-only tools are able to repair SQL databases by using fast yet sophisticated scanning algorithms thereby ensuring safe recovery of the corrupted database.
