SQL Server is a database management system largely used for storing and retrieving data by other applications. Developed by Microsoft, SQL Server uses three types of files to store and manage data – Primary Files (MDF), Secondary Files (NDF) and Log Files (LDF).
SQL Server database can be corrupted due to various reasons. MDF files are the primary database files holding the user data and its corruption can corrupt the entire database. There are multiple reasons that can cause MDF corruption such as:
In case of MDF corruption, SQL database becomes inaccessible. If you try to access the corrupt database, you might get different error messages. Some most common error messages are:
And, there are several other error messages you might get while trying to open a corrupt SQL database. If you’re a database administrator, you need to act immediately to prevent any kind of data loss. Read on to know the solutions to restore corrupt SQL database.
The main job of the Database Administrator is to keep the database highly secure and available. When there is corruption in database files, then sometimes it may not show any symptoms of error but the data remains unavailable. That’s why the administrator should employ some methods that check the health of the database to find any errors or corruption.
Run the command and see the results.
The command will check the physical and logical integrity of all the database objects like tables, triggers, relationships, dependencies, and if it finds any problem, then it will be shown in the result with the error message. The error message will clearly show the details like why it showed the error and stopped the process from finishing.
There are few manual solutions to repair corrupt SQL database but they do not guarantee the database recovery.
You can use the log files (NDF) of SQL Server to restore the database. However, log files are not sufficient enough to recover the database in many corruption cases. Sometimes, backup files also get corrupted if the corruption is severe.
Another way to repair the corrupt SQL database is using the database console commands i.e. DBCC CHECKDB and DBCC DEBREPAIR. They can be useful to fix minor SQL database corruption issues but they aren’t very much efficient though for all corruption cases. And, performing database console commands require certain technical knowledge which might be confusing for non-technical users.
Thus, using an authentic third-party software is the best way to repair and recover corrupt or damaged SQL Database. It is the best software available to fix database corruption errors.
