SQL is one of the best and most widely used RDBMS (Relational Database Management System) worldwide. But users face several errors while using it. One of the most persistent issues of Microsoft SQL Server is error 926. This error forbids the users from opening the database and executing the queries. 

The following error message is visible on getting error 926:

If you are also getting the same error repeatedly, then we are here with the best solutions to fix the SQL Server error. But before going to learn the fixes, let us first look at the reasons behind the error 926.

There can be multiple reasons for the latter error. Some of the causes for Microsoft SQL Server error 926 are as follows:

• It can occur if you have not attached the SQL database accurately.

• Also, it can happen while starting a SQL Server instance.

• Additionally, operations such as RESTORE database or RESTORE LOG commands can also be responsible for such errors.

Now that you know the causes. Let us explore the short tricks which one can opt for fixing the SQL Server database error 926.

Manual Fix for Microsoft SQL Server 2016 Error 926

First of all, you should check the SQL Server error log to find the reasons for the error. Most probably, database corruption or hardware issues are the factors responsible for such an error. Firstly, try to fix the hardware issue. And if that doesn’t work, then try to restore the last backup. Also, you can use DBCC CHECKDB repair options if you don’t have a backup. 

Moreover, if nothing works, then proceed with the following method divided into two parts which are as follows:

Part 1: Repair database by using EMERGENCY Mode

Part 2: Moving and detaching MSDB file

Let us now look at these in detail.

Repair Database by Using EMERGENCY Mode

Follow the given steps to fix Microsoft SQL Server error 926:

• First of all, launch a new query window in SSMS (SQL Server Management Studio) and execute the commands given below.

• ALTER DATABASE DB_Name SET EMERGENCY

This command allows users read-only permission to access the database by putting it in Emergency mode.

• DBCC CHECKDB (‘DB_Name’);

DBCC CHECKDB is the inbuilt tool to check and repair any issues in a SQL database.

• ALTER DATABASE DB_NAME SET SINGLE _USER WITH ROLLBACK IMMEDIATE;

It provokes the single-user mode.

• DBCC CHECKDB (‘DB_Name’, REPAIR ALLOW_DATA_LOSS);

This command will repair the errors in the database.

• ALTER DATABASE DB_Name SET MULTI_USER;

Lastly, this command will set the Microsoft SQL Server database to multi-user mode.

After all of the above, if you can access the database, reset it to the normal mode. And if still, you are unable to access the database, then move to part 2.

Moving & Detaching MSDB File 

If repairing the database from emergency mode does not fix the error, then one can use SSMS or T-SQL. You can recover them by moving and detaching MSDB databases as follows:

• First, launch Object Explorer in SSMS.

• Now, press Stop from the sub-menu obtained by right-clicking on the connected SQL Server instance.

• After that, browse and select Administrative Tools from the Control Panel and then hit Services.

• On the following dialog box, right-click on SQL Server (MSSQLSERVER) and click on the Stop button.

• Now, go to the following location:

C:\Program Files\ Microsoft SQL Server\ MSSQL10.MSSQLSERVER\ MSSQL\ DATA

• After that, move the .mdf and .ldf files to any other location and then copy them back to their original place.

• Restart the SQL Server Service again.

• Finally, detach the MSDB file after refreshing the database. 

These methods are worthy for giving a try, but they also have several drawbacks, which are as follows:

• Risk of loss of data integrity

• Time-consuming

• Higher chance of data loss on using DBCC CHECKDB ‘REPAIR_ALLOW_DATA_LOSS’ command.

• It is not suitable for repairing large databases or heavily corrupt databases.

Now, you are familiar with the manual method and its limitations to fix Microsoft SQL Server error 926. To overcome all the drawbacks of the manual process, I would like to recommend you use a third-party utility to fix error 926.
