Structured Query Language or SQL is used to communicate specifically with relational databases. SQL statements perform complex tasks such as updating or retrieving a database. Some of the most popular relational database management systems that use SQL are Oracle, Access, Sybase, Ingres, Microsoft SQL Server, and more. These databases contain data or information which is stored in tables. For various reasons, SQL databases can go corrupt. In such situations, a database backup can save a lot of time and effort. Hence, administrators always recommend backing up databases on a regular basis. Lost or deleted databases can be recovered and restored instantly if you have a backup. Now, we’ll see the reasons for database loss in SQL server.

Reasons for data loss issue

It’s important to know the reasons before recovery of deleted SQL database items. These are some crucial reasons that may result in data loss:

  • MDF and NDF files are damaged.
  • Corrupted file system.
  • Power failure or malware attack.
  • Hard disk-related issues.
Why is database recovery necessary?

Database recovery ensures the availability of a database. It is important to maintain backup and recovery processes regularly. Database recovery involves mechanisms to restore the database quickly and accurately after loss or damage. This ensures availability in the case of an outage and more importantly data integrity.

Some useful SQL commands for database recovery

There are some essential commands that can be used to perform the SQL database recovery process:

  • DBCC CHECKDB: This command checks the physical and logical integrity of all the objects in the specified database by performing the following operations:

    Note: The above commands can’t be executed separately from DBCC CHECKDB.

  • Using the REPAIR_ALLOW_DATA_LOSS command may result in data loss. It might result in more data loss than anticipated, but it is worth trying once, if all the other options fail.

    Before that, the database should be set to the single-user mode as follows:

    Next, run CHECKDB with REPAIR_ALLOW_DATA_LOSS as follows:

    Note: In the above SQL query, “Testmachine2” is the name of the affected database. Replace this with your affected database’s name.

  • DBCC CHECKDB with REPAIR_FAST: It does a minor but fast repair of the database without the risk of data loss.
  • Note: Make sure that the database is set in a single-user mode before running this fix.
