[T-SQL] Truncate Log File

Few days back , i was called by my friend who was working on community database with a problem that log file of his db was growing bigger and he was worried about it. So i went there and saw that its not a big issue and told him that i would prepare a script and give him so that he could run that once in a month:

USE TEST;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE TEST
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (TEST_log, 1);
GO
-- Reset the database recovery model.
ALTER DATABASE TEST
SET RECOVERY FULL;
GO
