With the help of this technical write-up, we will learn the possible causes of the error and then look for the best ways that will help with resolving such errors. 

Let’s begin by understanding the error first to make it clearer for the users about what the error is and how it affects their day-to-day tasks. 

Understanding SQL Server Error 1814 & Its Causes

When the database administrators encounter the issue, they often get confused about why the error might have occurred and how it can risk their databases and data stored in them. The error code 1814 SQL Server specifies that the database engine is unable to create or even open the database or database files in SQL Server. There us bo specific cause for this SQL Server Service Error code 1814 to occur; furthermore, it can occur in various situations. Some of these scenarios are given below:

• Due to a TempDB creation failure.

• If there are any permission issues within the SQL Server environment.

Common Causes for SQL Error 1814 Explained

The SQL Server error 1814 is mainly associated with TempDB failure. Simplifying this, every time the SQL Server engine starts, it recreates the tempdb database, and in case there is any creation issue, it might lead to the error. However, this is not the only cause for the occurrence of this error. Let’s now take a look at some of the most common causes for the error.

• Disk space insufficiency.
• File paths that are invalid or missing.
• Security restrictions or permission issues.
• Several Disk issues or SQL Server storage corruption.

These are some of the common causes that lead to SQL Server Error 1814. Now, to resolve these issues, we will take a look at the best troubleshooting methods for the best results. 

Best Ways to Resolve Error Code 1814 SQL Server – Step By Step Explanation

To resolve the error efficiently with the desired results, we will now discuss the ways we tried and explain how using them can help with resolving the issues. All of these methods are troubleshooting ways that allow users to fix this error and further carry out their day-to-day tasks. 

Method 1: Fix Disk Storage Issues To Resolve the Error

As we read earlier, one of the causes for the occurrence of this error is the storage issue in the disk. So, to resolve the error, if it occurred due to this reason, the best way is to clear up storage and free up disk space for the SQL Server engine to work properly. Doing this will help, as when the error occurs, it mainly specifies that there is an insufficient disk space issue, and the database is unable to create or open the desired file. Below are a few things users and database administrators can do to fix the SQL Server error 1814:

• Delete unnecessary files from the disk that might be taking up too much space and restricting SQL Server engine from creating new files. 
• If any data is not related to SQL Server, it will be helpful to move that data to another disk. This will help with freeing up space for the SQL Server engine to work properly. 
• If possible, expanding the disk volume will also help in preventing the error from occurring. 

Method 2: Use the Correct File Path to Fix Error Code 1814 SQL Server

One of the causes of the error is a missing or incorrect file path. Therefore, this error can be resolved by using the correct file paths and further verifying them when working on the SQL Server database. Here is how this method might help and how it is effective for users to continue working on their databases. 

• If the SQL Server fails to find the physical path of the desired database files, the error code 1814 will occur. Hence, it is important to check whether the file path being used exists or not. 
• If the disk letter in the file path is changed, the SQL Server engine will fail to fetch the database files, further resulting in the error itself. Therefore, this can be resolved by verifying the file names before initiating with any operations. 
• It is important to identify the incorrect file path and correct it to fix the error effectively. 
• If the folder storing the database files has been accidentally deleted, the database administrators need to recreate these files to resolve the error in a hassle-free way. 

Method 3: Resolve SQL Error 1814 by Safe Restore Method

We earlier read how restoring or attach database SQL Server operations can also be a possible reason for the occurrence of this error. This can happen due to permission issues in the database while restoring or attaching the database, or even due to incorrect file paths. This can be resolved by the following steps:

• Restore the databases using WITH MOVE and using the correct file paths for the desired database files. 
• Also, if there is an existing database file with the same name, change the name of the file to fix the error. Renaming the database file will allow users to prevent database error 1814 from occurring. 
• Also, it is important to grant and manage crucial permissions for the database to restore or attach files.

Method 4: Resolve SQL Server Error 1814 By Fixing SQL Account Permissions

One of the reasons for the error occurrence is permission issues or security restrictions in the database. So, to resolve the issue, it is important for the users to grant the SQL Server Service account permissions. Without necessary permissions, the users might encounter errors like SQL Server error 5120. It will make it easier for the database engine to access and have complete control over the data folders. Granting access to the files and folders will allow the database to access the backup files and log files effectively for better results. 

Conclusion

Several reasons might lead to the occurrence of SQL Server Error 1814. In this technical write-up, most of the causes & how they further result in the error is explained. Additionally, we have added the best solutions to resolve the error in a much convenient way.
