In the last blog, I discussed the process of shrinking the database size to make it easier to move around. The process involved detaching the database and reattaching it. I've an email from one of the readers asking if this can be done while the database is online.
Well, the answer is yes. You can shrink the log file while the database is up. There are two commands that one can use to truncate a log file to reduce its size. They are Backup Log and DBCC ShrinkFile.
Backup Log demo01 with truncate_only
DBCC ShrinkFile('demo01_log', 1)
The commands above will truncate the log file and reduce its size to one megabytes. Before this is carried out though, I highly suggest that you backup your database first.
