This is a quick way to reduce the size of a database log file. As a caveat to beginners, this should not be used on mission critical db systems. It is intended as a quick and dirty fix for non-essential systems.
For those not familiar with the Attach and Detach commands:
--You need to make sure the database is not being used by anyone else/any other process. That is why there is a set single_user statement.
--If your database has multiple files/filegroups, you need only specify the primary file in the create statement (if you haven't made any file modifications after detaching).
-- You may need to enable xp_cmdshell therefore I've included the sp_configure statements.
