How do I truncate the transaction log in a SQL Server 2008 database?
What are possible best ways?
I tried this from a blog as follows:
1) From the setting database to simple recovery, shrinking the file and once again setting in full recovery, you are in fact losing your valuable log data and will be not able to restore point in time. Not only that, you will also not be able to use subsequent log files.
2) Shrinking database file or database adds fragmentation.
There are a lot of things you can do. First, start taking proper log backup using the following command instead of truncating them and losing them frequently.
BACKUP LOG [TestDb] TO DISK = N'C:\Backup\TestDb.bak' GO
Remove the code of SHRINKING the file. If you are taking proper log backups, your log file usually (again usually, special cases are excluded) do not grow very big.
