There could be a wide variety of reasons that can lead to SQL server error 824. Here I have listed the primary causes:
As you have known the significant factors, now, it’s time to troubleshoot this error using the best methods.
In this section, you will find easy ways to fix SQL fatal error 823 manually. Also, you will learn how to get rid of it using automatic SQL recovery software.
If you are unable to access the SQL Server database due to error code 823, you should first check for the available backups.
However, if you are one such user who used to create a backup of your database regularly, then you can easily restore SQL Server DB from the available backup.
In the absence of a backup, you can try the below tricks to troubleshoot this error.
Well, there are various statements & commands in the SQL Server Management Studio that helps to check and solve the Server error. One such statement is- DBCC CHECKDB.
Here, you can also use the DBCC CHECKDB command to repair the SQL database and get rid of this error.
Run the below T-SQL query –
DBCC CHECKDB (DB_NAME, REPAIR_REBUILD);
Nonetheless, to repair the SQL database, it is important to restrict its usage to a single user. However, you can run the below T-SQL statement to change the database to the Single-user state:
ALTER DATABASE DB2 SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
Now, you can simply take assistance from a SQL Server Management Studio in order to change the mode of the user. All you need to do is to navigate to a database >> make right-click on that. After that, in Restrict Access, you have to choose the feature “Options.” Next, choose a SINGLE USER mode >> click OK.
Once you have successfully changed the mode of the user, you will have to again run the statement ‘DBCC CHECKDB’ to verify the fixed database.
