The SQL Server Database can work in various different states such as ONLINE, OFFLINE, RESTORING, EMERGENCY, SUSPECT, etc. State here implies the current running mode in which the database is working. At a time it can only reside in one state. In every state, the SQL server database possesses different properties. In this blog, we are going to discuss the suspect mode and about the methods to recover the database from the suspect mode in SQL Server 2016.

To check the state of the database we can use two methods:

  • By running the query- Select name, state_desc from sys.databases
  • By using DATABASEPROPERTYEX and status

Before going further we need to understand that what are the reasons due to which SQL Server Database goes into the suspect mode.

Suspect mode indicates the corruption of Database Server due to which users can not access the database and the risk of data loss is there.

Know The SQL Server Suspect Database Causes

  • Corruption in DB files.
  • Missing log file
  • Hardware failure
  • Crashing of SQL Server
  • Power failure
  • Improper shutdown of SQL Server
  • Less Disk space available

There are more such reasons that lead the DB in the suspect state. As we know that when a DB is in the suspect state it becomes unavailable to the user and is prone to data loss. In such a scenario the user is unable to access the Database and even the recovery of databases becomes difficult. Therefore, there is a need to recover the database from the suspect mode in SQL Server by taking appropriate strong steps for the same. For an instant solution, you can use the SQL Database recovery tool.

I am using SQL Server version 2016, I am unable to access my database as SQL server shows that the database is in the suspect state. I do not even have the backup of the database. If anyone knows how to recover the DB from the suspect mode in SQL Server version 2016, please let me know.”

We can do this by using two approaches, one is manual and the other is by using an automated tool.

For this, you need to set the database to EMERGENCY mode.

Step1: Launch the SQL server management studio.

Run the query “ALTER DATABASE DATABASE_NAME SET EMERGENCY”

Step2: For checking consistency, run the command-

DBCC CHECKDB (Database_Name)

Step3: Run the following command to recover the database-

DBCC CHECKDB (Database_Name, REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS, NO_INFOMSGS;
GO

Step4: Set back to multi-user state by using the command ALTER DATABASE Db_name SET MULTI_USER

By using the manual method we can repair DB from the suspect state but it might be difficult for a nontechnical user to use the manual approach. It requires more technical knowledge and consumes more time.

Efficient Application To Resolve Suspect Database Issue

In case of extreme corruption or damage to the SQL database, the manual method will not work, hence it is better to use a third party automated tool to resolve this problem.

The SQL recovery tool works efficiently even in case of severe file corruption and recovers all the data from the affected files. It provides more accuracy and consumes very less time to recover DB. The demo version of the software is also available for trial purposes. The demo version allows you to preview the recovered data. This software repairs and recover the corrupt files of suspected databases efficiently and saves them to the MDF files of the server.

Conclusion:

In this blog, we have discussed how to recover database from the suspect mode in SQL server by using both manual and automated approaches. Manual methods are more time consuming and are not efficient for severe corruption. So, to resolve the issue it is recommended to use third-party software that overcomes all the drawbacks of the manual method. SQL recovery tool is the best recovery software to repair every type of corruption and it provides a feature to recover all the deleted records from the databases.
