Temporary Solutions to Fix SQL Error 926

Before we dive deeper into the standard methods to fix the SQL Server Error 926, there are some temporary fixes you can try to resolve the issue.

  • Restart your connection to SQL Server
  • Disconnect the server from your system and reconnect
  • Restart the SQL Server Management Studio (SSMS)
  • Restart the service SQL Server
  • If the above solutions don’t work well for you, you can move on to the below methods to fix the error.

Method 1st – Perform the DBCC Check

The first method to fix the error is to perform the DBCC check with the below steps:

  1. Open a new window in the SQL Server Management Studio (SSMS) and execute the query:
  2. EXEC sp_resetstatus ‘DB_Name’

    Note: In the database, sp_resetstatus disables the suspect flag and updates the status column and mode named sys.databases.

  3. After that, execute the below query to set your database into single-user mode:
  4. MODIFY DATABASE DB_NAME SET SINGLE_USER WITH ROLLBACK IMMEDIATE
  5. Again, use the below command to set the database to multi-user mode to make it accessible for everyone:
  6. ALTER DATABASE DB_Name SET MULTI_USERDetails
  7. Run the below command, and if the SQL database is set to EMERGENCY mode, its status changes to READ_ONLY copy. After this, only the sysadmin members can access it.
  8. ALTER DATABASE DB_Name SET EMERGENCY
  9. Now, run the DB check command to check the integrity between the objects:
  10. DBCC checkdb (‘DB_Name’)
  11. Finally, to repair the errors in the SQL databases, run the below query:
  12. DBCC CheckDB (‘DB_Name’, REPAIR_ALLOW_DATA_LOSS)

    This method will definitely fix the error. However, if it persists, move the second method mentioned below.

Method 2nd: Move and Detach MSDB File

Another method to fix error 926 is moving and detaching the MSDB file. Follow the below steps to execute this method:

  1. Open MySQL Management Studio and click on Object Explorer. In the opened connection, right-click and select Stop.
  2. Go to the Control Panel on your system, click on Administrative Tools, and select Services.
  3. Emphasize the SQL Server (MSSQLSERVER) item from the services tab and right-click on it. Then, click Stop from the opened menu list.
  4. Go to the following path in your C drive:
  5. C:\ProgramFiles\MicrosoftSQLServer\MSSQL10.MSSQLSERVER\MSSQL\DATA
  6. Now, find the MSDBData.mdf and MSDBlog.ldf file and move it to another location.
  7. Copy the files from the new location and paste them back to the older place.
  8. Now, in the opened connection in Object Explorer, right-click on it and select Start.

Limitations of Manual Methods

The above methods might be helpful in resolving the SQL Server Error 926, but it does have some limitations. Executing the above commands is a complex process that requires time and knowledge of SQL queries. Besides, there are chances that you might make mistakes while executing the commands.

Another drawback is that the manual approach is completely unstable for naïve and non-technical users as the process revolves around technical terms. So, what is the alternative solution to fix this error?
