In SQL Server data is stored using two physical files:
- (.mdf) extension which contains the data.
- (.ldf) extension which contains log.
Log file size increases very rapidly and depend on the operation performed on the data. After a long time period this file becomes too large. When log file is too large it takes time to perform some operations like (attach, de-attach, backup, restore… etc ).
Step 1. Copy/type the below given SQL.
Step 2. Change @DBName to <Database Name>, @DBName_log to <Log File Name>
Step 3. Execute the SQL.
ALTER DATABASE @DBName SET RECOVERY SIMPLE WITH NO_WAIT DBCC SHRINKFILE(@DBName_log, 1) ALTER DATABASE @DBName SET RECOVERY FULL WITH NO_WAIT GO
