The only thing often prevents the shrinking of a log file is an active transaction.
Dbcc opentran(database)
Only when this transaction is terminated will you be able to shrink the LogFiles.

Following up on what arnold said.

Typically you will need to put the database in SINGLE_USER mode which may not be feasible for business purposes depending on how your database is used.

USE Master;


Open in new window

DBCC SHRINKFILE(<logical filename>, <desired size in MB>)

When you are done, don't forget to return the database to MULTI_USER.


Open in new window

Sometimes the indexes for the tables can take a lot of space.  You can reindex each table by running the following command on the tables in the database

dbcc dbreindex ('table_name','',70)

run the shrink after you are done and this may free up more space
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

The shrink is on the transaction log file not on the DB files. Reindex is not advisable as that will add to the transaction log.

I rolled back and tried to shrink with the command but it gave me below message

DBCC SHRINKFILE (mydb_log.LDF, '8968')

Incorrect syntax near '.'.

Do i have to run that command on each table?


Yes i am trying to shrink log file (.ldf)

I was able to shrink the log file by switching the "recovery model" of the database to "simple"

Note that simply shriking the log file now, does not resolve the reason it expanded.  The change in recovery model if left permanently could have an adverse impact when a restore to a point in time is needed.
If left unresolved, and recovery mode returned to Full, you will once again run into this same situation as you've not resolved its cause.

A change to simple with an active transaction would not have allowed you to shrink the DB meaning the active transaction preventing the shrinking of the log file had been terminated, i.e. SSMS session you have was closed and reopened.
