This blog is composed to present the multiple methods to import MDF file to SQL server database without the LDF log file when the MDF file is in a corrupt or missing state.
As users know, SQL Server is a famous application for storing and managing large amounts of data, has database files to store its information. Basically, it has two types of files. The MDF files are the primary files of the SQL server database which are used to manage the schema and data. Other than this database file, the LDF file is the Log Database File, which stores transactional or log information of the SQL database. Furthermore, the LDF files can also be used for checking the logs in case of corruption. Sometimes, these log files get missing while attaching the MDF file to the server, and the process fails due to this. In such circumstances, one job can be done – attach MDF without LDF log file. After the MDF file is successfully added, log files would be generated automatically.
Now, let’s learn the cases in which the LDF files are missing.
Why Add MDF file to SQL server Without LDF?
When the user try to attach or import MDF files in SQL and if you are getting an error message while attempting this process, it means your SQL Server database files have some corruption issues. You cannot take the log backup if there is corruption in your LDF file. As your LDF files may be missing due to corruption. In this situation, you can attach your MDF file without the LDF file and restore the MDF file SQL server. This can further resolve your problem if your log files are deleted intentionally or unintentionally.
So, in the below section, I am going to discuss various techniques to attach MDF files to SQL server.
There are primarily two techniques to attach SQL MDF files without LDF manually.

This technique needs some technical skills and prior knowledge of running scripts.
The techniques mentioned above do not work if your database MDF file is corrupted. In such circumstances, it is recommended to use the SQL Database Recovery tool. The software can efficiently scan and repair corrupt database files in just a few simple clicks. After the file is repaired successfully, you can easily import MDF file to SQL server database environment.
