Each SQL Server database contains a transaction log file (.ldf) that records all transactions and changes made by each transaction. This log file is an important part of the database, and SQL Server uses it to restore the database to a consistent state in case of system failure.

While attaching the SQL database, you also require the transaction log file, along with the MDF file. However, you can attach the database even without the transaction log file. In this article, you will learn how to attach a SQL database without a transaction log file.
