How to Fix Microsoft SQL Server Error 926? Step-by-Step

When I opened the SQL database, I encountered error 926 and marked my database inaccessible. Due to this, my application connected with the database has also stopped working. I do not have the exact idea, but I think it is the issue of the MDF file or database corruption.

What is Microsoft SQL Server Error 926?

This error appears when the SQL Server can’t access the database during recovery. Mostly, the database becomes unavailable due to corruption or damaged MDF files. If this happens, then the SQL Server may mark your database as suspected or inaccessible to prevent further damage. 

This error occurs generally when you open a database, connect an application, or restore the database. It is noticed that the SQL Database Error 924 also appears with 926 sometimes. It happens because both errors are related to the database recovery problems.

A common error message may look like this:

“Database ‘Database_Name’ cannot be opened. It has been marked SUSPECT by recovery.”

This error should not be ignored because it may indicate serious corruption inside the SQL database files.

Common Causes Behind SQL Server Error 926

Cause	How It Affects the Database
Corrupted MDF/NDF Files	Damaged database files can make the SQL database inaccessible.
Sudden System Shutdown	Interrupts active database operations and recovery processes.
Power Failure	May leave transactions incomplete and corrupt database records.
Damaged Transaction Logs	SQL Server may fail to recover the database properly.
Improper SQL Server Shutdown	Can force the database into suspect mode.
Hard Disk Issues	Bad sectors or storage failure may damage SQL files.
Low Disk Space	SQL Server may stop processing database operations correctly.
Virus or Malware Attack	Harmful programs can corrupt database files or server components.
Hardware Failure	Faulty RAM, storage devices, or controllers can affect database stability.
Recovery Process Failure	SQL Server may fail while trying to recover the database during startup.

Fix SQL Server 926 Error Manually

There are several ways to fix the SQL Server 2008 R2 Error 926. In this section, we have discussed the two methods that you can try to fix the error. Follow the methods below in a stepwise manner.

Method 1: Fix the Error 926 Using Commands

1. Firstly, open a new window and use the query given below:
   EXEC sp_resetstatus ‘DB_Name’
2. In a database, sp_resetstatus disables the suspect flag. Basically, it updates the status column as well as a mode that is named as sys.databases. You’ll get the sysadmin rights to perform this action only when you have login details.
   ALTER DATABASE DB_Name SET SINGLE_USER WITH ROLLBACK IMMEDIATE
3. This query will set your database into single-user mode.
   ALTER DATABASE DB_Name SET MULTI_USERDetails
4. You can set your database into multi-user mode by using this command.
   ALTER DATABASE DB_Name SET EMERGENCY
5. It becomes a READ_ONLY copy if your SQL database has been set to EMERGENCY mode. After that, only the sysadmin members can access it.
   DBCC checkdb (‘DB_Name’)
6. Use this command to check integrity.
   DBCC CheckDB (‘DB_Name’, REPAIR_ALLOW_DATA_LOSS)
7. Use the above command to repair the errors.

Method 2: Via SQL Management Studio (SSMS)

1. Open MS SQL Management Studio (SSMS) and then on Object Explorer. After that, in the opened connection item, right-click and choose Stop.
2. Now, open the Control Panel on your computer.
3. After, Click on Administrative Tools>>Services.
4. Now, highlight the server (MSSQLSERVER) item >> right-click on it.
5. Then, click on Stop from the opened menu list.
6. Following the path:
   C:\ProgramFiles\MicrosoftSQLServer\MSSQL10.MSSQLSERVER\MSSQL\DATA
7. Now you have to move the MSDBData.mdf data files to MSDBlog.ldf to a different location.
8. Now, copy-paste this file from a new location to the old location.
9. Click the Right-click the mouse button and then on the Start option.
10. Now, refresh your database.
11. Finally, one can detach the MSDB File.

With the methods above, you can fix the error 926. But the manual process involves many steps, and the execution of this method is also difficult. Therefore, in the next section, we have described the alternative solution to fix it.
