Therefore, we come across the best solution to recover SQL server database from suspect mode. This article will help you to understand the problem and how to solve it quickly.
What do you mean by SQL Suspect Mode?
It is one of the SQL database states that shows the start of the recovery process but has not been successfully completed. The user will not be able to access the databases during the server startup when the server is in suspect mode.
Why SQL Server Database marked as Suspect?

- Due to file corruption in the Database.
- Absence of any database files
- When SQL database server not properly shutdown
- Device opening failure where the data or the log file resides
- Crashing of SQL server
Now, after knowing the reasons, you must know the solutions to carry SQL database Suspect mode to Normal mode.
How to recover SQL server database from Suspect mode to Normal mode?
There are several manual ways to recover SQL server database from suspect mode to normal mode as mention below:
Manual Methods to Recover SQL Server Database from Suspect Mode-
- Check the status of SQL database’s suspected mode
The first thing to do in this case is to check the suspected status of the database. You can check this by accessing data from the database using the following command. If the database is suspected, an error message may result from the command:
Command: SELECT *FROM database_name..table_name
- Database setting in Emergency Mode
Use T-SQL commands to set in emergency mode as mention below:
Command: ALTER DATABASE mydatabase SET EMERGENCY
Example: if you want to check the database named “ABC” are in the emergency mode or not using T-SQL, run the following command:
The database will be signed by a yellow sign if it is in the emergency mode like this:
To set the SQL Database from emergency mode to normal mode, set online by the following command as follows:
Command: ALTER DATABASE mydatabase SET ONLINE
Nevertheless, if your database’s suspect status is affected, setting ONLINE will only revert to a suspect status database and you can not access the information.
- Return back from Database to Multi-User Database
After the completion of the repairing process, allow multi-user access to the database using this command:
Command: ALTER DATABASE SET MULTI USER WITH ROLLBACK IMMEDIATE database name
- Use DBCC Commands to Recover SQL Database From Emergency Mode
If the above process fails, then run DBCC commands to restore data as follows:
Command: DBCC CHECKDB (dbname, REPAIR_ALLOW_DATA_LOSS)
Here, the DBCC commands repair the database.
- Using ROLLBACK, recover SQL Database From Emergency Mode to normal mode
Use T-SQL commands to restore the database to the normal state as follows:
Command: ALTER DATABASE dbname SET MULTI_USER WITH ROLLBACK IMMEDIATE
If the above procedure fails for databases of large size. So, for better results, you can use third party SQL Database Recovery utility to tackle this issue. This utility easily solves SQL Server Database to recover SQL Database in Suspect Mode problem.
We have mentioned about the Suspect state in this blog first then we provide reasons for the suspect state. After that, all manual approach has been given to recover SQL server database from Suspect Mode but it has some limitations with the large-sized database.
