How to Bring Database Online from Emergency Mode in SQL Server

The database is essential for every user since it preserves all of an organization’s vital information. It is highly susceptible to numerous issues due to the vast amount of data it contains. There are a number of situations where the SQL Server database becomes inaccessible and is flagged as Suspected. Additionally, until a database is backed up, a user is not permitted to view it or take any actions on it while it is in emergency mode. The processes for fixing a faulty SQL database and returning from emergency mode to normal mode will be covered in this article.

What does SQL Server’s Emergency Mode mean?

Let’s first define emergency mode before understanding how to recover the database from it. When the database’s transaction logs are damaged and there isn’t a recent backup, the emergency mode is essentially employed. The standard repair command will not function in this circumstance. The reason for this is that when the transaction logs are damaged, repairs are totally logged and cannot be used. Additionally, users have access to the database even while it is in emergency mode. Additionally, the ability to access the suspicious database and restore it from emergency status is granted with Read-Only permission.

Why do Users Restore Databases in Emergency Mode?

There are numerous reasons why the SQL database enters suspicious status. However, some of them are more frequent than others. Therefore, we explore several common causes for the SQL server issue before you bring the database online from the suspect mode in the SQL server.

     Database Corruption: If your SQL database is flagged as questionable, it may become corrupt.

     Malicious Attacks: The SQL server database entering suspect mode is also a result of any malware attack.      Hardware Issues: This issue may potentially be related to any hardware issues.

     Log File Corruption: Every SQL database has a transaction log that keeps track of all transactions and database changes. The SQL database could become corrupt for any number of reasons, including a faulty transaction log file.

     Improper System Shutdown: This is the most frequent cause of corruption problems. Therefore, it is advised to prevent erroneous system shutdowns.

How can SQL Database Be Recovered From Emergency Mode To Normal Mode?

Follow the procedures listed below to learn how to recover a database using emergency mode:

1. Verify the suspected status of a SQL database

Verifying if the database is in the suspected state is the first step. Run the command listed below to access the database’s data and do the same action. However, the command will produce an error message if the database is questionable.

SELECT name, state_desc FROM sys.databases WHERE name = Test_Database

2. In emergency mode, move the SQL Server database

Simply activate the database’s emergency mode by running the following command after you are certain that SQL is in suspect mode:


3. To repair SQL Server, use DBCC CHECKDB

You can begin the procedure to restore the database from emergency mode as soon as the emergency mode is activated. But by removing all incompatibilities that are the cause of the suspected mode, this repair command will assist. Now, a user must switch the database to single-user mode in order to perform the same action.

Note: Some data loss may occur throughout this process.


4. Enable Multi-User Database Access

Simply turn on multi-user access to the database after the successful completion of the repair operation by using the following command:


5. Online the Database

To recover the database and return it to online mode, you must finally run the following command.
