Open LDF File

A log file or extension LDF (Log Database File) is a Microsoft SQL Server database file, which stores all the transaction/event logs, running on the database.

Microsoft SQL Server is a Relational Database Management System, or RDBMS, that supports a wide variety of transaction processing, business intelligence, and analytics applications in corporate computing environments.

Microsoft SQL Server is one of the three leading database technologies on the market, along with Oracle Database and IBM's DB2.

The main purpose of using the LDF log file in SQL Server is to roll back the database in case of data loss.

The log file uses the same file name as its associated MDF file, ie if the MDF is named 'units.MDF', then the LDF will be named 'units.LDF'.

The LDF file can be opened using the SQL command line program.

Each transaction or rollback command has a different syntax for each LDF file.
