Summary: This blog is dedicated to elucidating SQL Server error 926, a frequently encountered issue among SQL users. Numerous queries have been posted on SQL forums concerning error 926. Additionally, this article aims to emphasize both manual and alternative approaches for resolving SQL Server 2008 R2 Error 926.

Undoubtedly, SQL Server stands as a prominent choice among contemporary database management systems. It empowers users with enhanced flexibility and efficiency in database administration and optimization. However, like all well-crafted applications, SQL Server is not without its imperfections. Many users encounter a variety of errors during their interactions with SQL databases at various junctures. Among these, Error 926 is notorious for disrupting SQL transactions, thereby impeding the seamless operation of the SQL Server.

Error 926 occurs when attempting to connect to an SQL instance using sysadmin login credentials and SSMS. This error is displayed when the database is marked as “Suspect” due to a failed recovery process. Nevertheless, there are additional scenarios in which the SQL 926 error may also manifest on the screen, such as:

  • While extracting transactions from the SQL database log
  • When a database is attached to the SQL Server by the user
  • While restoring the database in the SQL server
  • So, what causes the SQL Server 926 error, and how can it be resolved quickly?

    In this blog post, we will address your queries, shed light on the underlying problems associated with this error, and present alternative approaches to prevent SQL error 926.

What Causes SQL Server 926 Error?

There are multiple reasons behind the SQL Server 926 error; some of the most common causes include:

  • If the header part of the system file is corrupted
  • Due to malware errors in the computer hardware
  • Abrupt shutdown of the SQL Server application
  • SQL database is marked as Suspect
  • While restoring the database in the SQL server
Temporary Solutions to Fix SQL Error 926

Prior to delving further into the conventional approaches for addressing SQL Server Error 926, consider implementing some interim solutions aimed at resolving the problem.

  • 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

To resolve the error, start by executing a DBCC check using the following steps:

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

    Note: Within the database, the sp_resetstatus function is utilized to deactivate the suspect flag and refresh the status column and mode found in the sys.databases table.

  3. After that, execute the below query to set your database into single-user mode:
  5. Again, use the below command to set the database to multi-user mode to make it accessible for everyone:
  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.
  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:

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

Method 2nd: Move and Detach MSDB File

An alternative approach to resolving error 926 involves relocating and disassociating the MSDB file. To implement this solution, follow the steps outlined below:

  1. Open MySQL Management Studio and click on Object Explorer. In the opened connection, right-click and select Stop.
  2. Navigate to the Control Panel in your system, access Administrative Tools, and then choose 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. In the active connection within the Object Explorer, simply right-click and then choose the Start option.
Limitations of Manual Methods

The aforementioned approaches can offer assistance in addressing SQL Server Error 926; however, they come with certain limitations. Carrying out the prescribed commands involves a complex procedure that demands both time and a proficient understanding of SQL queries. Moreover, there exists the possibility of errors occurring during the execution of these commands.

Another limitation is that the manual method proves to be quite unreliable for individuals who are inexperienced and lack technical expertise, as it heavily relies on technical terminology. Therefore, what other solution can be considered to rectify this issue?
