Best Ways to Fix SQL Server Error 1813 Without Any Data Loss

If you are working on an SQL Database, there are higher risks or coming across various errors. One of these errors is the SQL Server Error 1813. When a user encounters an SQL error, they tend to panic first as the major impact of any error falls on the database and the data in it.   

With this write-up, we are going to discuss the same issue. Additionally, we will be talking about the causes of the error, the challenges and the solutions to resolve the error. Let’s begin by understanding what the attach database error in SQL Server is.

What is SQL Server Attach Database Error?

When we talk about the SQL Error 1813, there are a few things we are aware of. Let’s list them up to understand the error better. 

• This SQL Database error occurs when the SQL Server attempts to attach a database or access a database but encounters issues during the process. 
• There can be various reasons that may contribute to the SQL server not being able to attach or access the database. 
• The major causes of this SQL Error to occur can be issues with the database files or due to the misconfigurations in the database or the server. 

If we talk about the actual causes, there are many of them. Here we will discuss a few of them to get a better idea about the issue.

SQL Server Error 1813 Causes

As we mentioned earlier, there can be various reasons for the error to occur. But the primary reasons are:

• I/O Errors During Write Operation: This error generally occurs when the SQL Server fails to attach the database due to the error during the write operation. The I/O error describes the failure during the input/output operation between the SQL Server and the disk. This operation failure can be further caused due to factors like:
  • Disk Failures
  • Corruptions in file systems
  • Connectivity issues
    
• Corruption in Database Files: This can also be one of the major reasons for the occurrence of the SQL Error 1813. If the MDF or LDF files get damaged or corrupted due to any reason, it can make it difficult for the server to attach the database. Therefore, it can also become one of the major causes of the SQL database error. 
  
• Misconfiguration of Databases: When there is a configuration issue with the database settings, it can make the process of attaching the database files difficult. 

So, for the SQL Database Recovery, it becomes necessary to know the actual cause of the error. If we talk about what may have caused the error,  the answer is a little straightforward. When the SQL Database error occurs, the error message displays the details of the error. The detail contains the error number, error severity and the error state that can help you to understand why the error may have occurred. 

Now as to understand what are the methods to resolve this error, we will proceed on with the solutions. There are different methods that will help you with the error.

How to Resolve the SQL Server Error 1813 Attach Database?

The first method we are going to discuss is the manual method for resolving this SQL database error. The method is as follows:

• Create a new database with the same name as the database that is to be fixed. It is necessary to recreate the MDF,NDF and the LDF files with the same names as well. 
• Put the SQL Server in the offline mode. 
• For the next step, replace the original MDF file with the newly created MDF file to move the original file to the new destination. 
• Now, delete the LDF of the new database.
• Put the SQL Server in the online mode again, you will see that the database has been marked as suspect.
• Use the following command to ensure that you can upgrade the values in the systems tables of the master database. 

USE MASTER 
GO
sp_CONFIGURE ‘allow updates’, 1
RECONFIGURE WITH OVERRIDE
GO

• Now set the database to emergency mode. Then use the command to retrieve the current status of the Database:

SELECT * FROM alldatabases WHERE name=Database_Name

• Next, run the following command for updating the row of the database. 

BEGIN
UPDATE alldatabases
SET status 32678
WHERE name = ‘Database_Name’
COMMIT TRAN

• Then, restart the SQL Server to resolve the SQL Error 1813.

(IMPORTANT: in case you miss or skip this step, the SQL Server may encounter an error)

• Open SSMS, and go to the query window for the execution of the DBCC command. This will create a new log file.

(REMEMBER: the newly created LDF file must have the same name as the deleted LDF file)

Use the command: 

DBCC TRACEON(3604)
DBCC REBUILD_LOG(Database_Name, ‘C: \Database_Name_log.ldf’)
GO

• Execute the following command to reset the database status:

sp_RESETSTATUS Database_Name
GO

• To turn off the updates of the Systems Tables of the master database, enter the given command:

USE MASTER
GO
sp_CONFIGURE ‘allow updates’, 0
RECONFIGURE WITH OVERRIDE
GO

• Put the database in the Single User Mode

sp_DBOPTION ‘Databse_Name’ , ‘single user’, ‘true’

• If the status of the databas still doesn’t change, try the following command:

sp_DBOPTION ‘Database_Name’ , ‘single user’ , ‘false’

This method needs complete accuracy while execution, and even a slight mistake can cause further errors in the repair process. Let’s try a more efficient and straightforward method to resolve the error.
