When corruption occurs in SQL Server database, the user faces many critical problems & issues. For instance, queries of database fail with serious errors & backup is inaccessible with critical errors. The SQL user must identify the kind of corruption by running the integrity check command. Running the CHECK DB command directly with one of the repair options isn’t recommended to avoid data hammering situations.

Open SQL Server Management Studio & then Run the ALTER DATABASE [db_name] SET EMERGENCY command.
This command will set your database in emergency mode. Now, we have o move to the second phase.
Phase #2
It’s time to find out the errors present in the server. To analyze the errors & fix SQL database corruption, simply run the below-mentioned command.
DBCC CHECKDB (N db_name) WITH ALL_ERRORMSGS, NO_INFOMSGS
After this, the software will present a report having the errors it found during the scan. It’ll also recommend you the minimum level of repair required at the bottom of the summary.
Phase #3
Here, put the database in single-user mode by running the ALTER DATABASE db_name SET SINGLE_USER command.
After this Run the DBCC CHECKDB (N ‘db_name, REPAIR_REBUILD) command or DBCC CHECKDB (N ‘db_name, REPAIR_ALLOW_DATALOSS) command.
And then Run the ALTER DATABASE database_name SET MULTI_USER command to set the database to multiuser again.
