How to repair corrupt SQL Database?
Repairing corrupt SQL Server Database can be a tedious task if you don’t know the right technique. There is manual technique available to repair corrupt SQL database but a professional and authentic third-party software is always the best approach to do it. There are plenty of software available online for the purpose but finding the best one is again a big task. Before knowing about the SQL recovery solutions, you should know about SQL Server and reasons of its corruption.
What is SQL Server?
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).
- Primary SQL Server database files have .MDF extension. Each database has one primary file and it store user data and objects including Indexes, Columns, Views, Functions, Values, Tables, Keys, Stored Procedures, Triggers, Default Values, etc. MDF files also store the startup information for the database.
- Secondary files are optional and have .NDF extension. You can create unlimited number of NDF files as per your requirement. Commonly used to spread data across multiple disks, NDF files can be used to store user data as well.
- Log files are basically the backup files of SQL Server database. They are used to restore the database in case of corruption. Log files have .LDF extension and store log information. Every database has at least one log file.
How to Identify MDF File?
MS SQL Server database corruption – how to identify and fix?
MS SQL Server, a Relational Database Management System developed by Microsoft, is widely being used by a great number of businesses to store their professional details. SQL has different editions that meet the requirements of clients ranging from small-size enterprises to large-scale corporate giants.
SQL corruption – common causes
MS SQL Server is vulnerable to different threats like database corruption and errors. Predominantly, it is the hardware errors that are responsible for the database corruption quite often. Faults in hard disk, controller, CPU, and memory unit can also harm the database as the SQL server is heavily dependent on them to store and retrieve the information. There major factors behind database corruption in MS SQL are–
- The memory disk’s subsystems which store the database details may get affected by various issues. It will lead to the improper arrangement of table details in the database and ultimately the user will not get the desired information he is looking to retrieve. Software bugs also can also cause SQL corruption.
- Anti-malware and anti-spyware are good for other files stored on the system, but they can be harmful for the SQL. That is why it is advised to exclude database from anti-virus scans.
- Many users like to compress the database to save some space. But the database files are not meant to be compressed. It may increase the chances of corruption. Keeping backup files in a compressed database also increases the chances of database corruption. If the user really wants to compress the database file, then he must use the in-built data compression and backup tools present in the SQL Server.
