4 min read

Summary: Are you looking forward to a quick solution regarding how to restore MDF file without log file. Here we will provide a step by step procedure to resolve such issues quickly.

Microsoft SQL Server is one of the most popular program used to store and retrieve data according to the requirement of other applications. SQL Server databases use different types of files – an MDF File also known as primary database file where all the database information is stored. Another is LDF or transaction Log File, which stores transactional or log information of the SQL Server database.

There are times when SQL database files get damaged and become inaccessible. At that point, users need to recover and restore the database file. Sometimes while restoring the SQL database files (MDF and LDF), the user is unable to connect the log file that means the transaction log file is lost. In such a situation, one thing can be done i.e. restore MDF file without log file. Once the SQL MDF file is restored successfully, the log files would be created automatically. Therefore, in this post, we are going to discuss some effective approaches that will let you know how to restore MDF file without Log File.

Manual Ways to Restore MDF File Without Log File

Using SQL Server Management Studio (SSMS)

Follow the steps mentioned below to restore MDF file without Log file:

  • Firstly, open SQL Server Management Studio on your system.
  • After that, right-click on the databases and then click on Attach from the drop-down list.
  • Here click on the Add button, browse the location of SQL database .mdf file >> choose the file, and hit the OKbutton.
  • Now, preview the database details in the Attach dialog box but you will notice that the Server is unable to find the log database files (.ldf).
  • To attach the MDF file without log file, select the LDF file and press on the Remove button.
  • After that, click on the OKbutton for restoring the MDF file without log file. During the restoration of the database, the SQL server will create a new Log file automatically.
