Microsoft SQL has its own identity these days and is a widely used database management system. You have important data there, and it is very easy to create a backup and restore the data in the time of uncertainties. I have heard of many cases where people have accidentally dropped a Database, and they do not have a backup to retrieve the data.
There are several parts of an SQL server which get affected by the data loss like Database file, Relational Database, client/server system and Database Management System which manages all these parts. The database file is a complex and organized file which has managed data; therefore it plays an important role. Relational Database is the way the data is organized which is in the form of tables. The client or server system works as the main communicator and users on multiple client machines connect to a server which is accessed by a machine through Local Area Network.

There can be many other reasons for data loss, but these three are the main ones. There are methods with the help of which you can recover the data you have lost. If the data loss has occurred to the file, then the possibilities are low due to the complex nature of the files. If the issue is with the file system, then the system needs to get repaired, which sometimes can get automatically if OS supports such a function. If there is a failure in storage device, then most probably this is the hard disk’s issue. Try to find the ways to make it work so that you can recover from that.
Recovering the lost data is not a big deal if you have the backup and know exactly how to recover the data. Here are some commands with the help of which you can recover the database.
Both commands can only be performed if you have Microsoft SQL Server Management Studio. For this, you first need to open it in your system and follow the below mentioned steps.
EXEC sp_resetstatus [DATABASE_NAME];
ALTER DATABASE [DATABASE_NAME] SET EMERGENCY
DBCC CHECKDB ([DATABASE_NAME])
ALTER DATABASE [DATABASE_NAME] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DBCC DATABASE ([DATABASE_NAME], REPAIR_ALLOW_DATA_LOSS)
ALTER DATABASE [DATABASE_NAME] SET MULTI_USER
You can use this method if you have a good understanding of the subject or you are under the guidance of a professional. If this process takes a long time to execute then might be the corruption is high, but if it is taking unusual time or fails to work, then it means that the corruption is severe. In this case, you need to take help of an automated method.
