If you lost your log file(*.ldf) with any reason, there is a simple way to recover the damaged DB, this solution is copied from

Microsot Experts Exchange forum, I have done my test, it works.

1. Stop SQL Server;

2. Backup mdf to a save location;

3. Start SQL Server, the DB will be suspect;

4. Run the following SQL to recover DB

ALTER DATABASE yourdb
SET
EMERGENCY;

ALTER DATABASE yourdb
SET
SINGLE_USER;

DBCC CHECKDB
(yourdb,
REPAIR_ALLOW_DATA_LOSS)
;

ALTER
DATABASE yourdb
SET
MULTI_USER;

ALTER
DATABASE yourdb
SET
