USE DatabaseName
DBCC SHRINKFILE(, 1)
BACKUP LOG WITH TRUNCATE_ONLY
DBCC SHRINKFILE(, 1)

Thank you so much
Mathi

I am using the SQL 2005, the log file is really big, I have found the reason and I can delete the item from the database,however what I should do with the log file, Is it possible if we can just modify the log file by items,I mean just delete the specific item in LogFile, or what I can do is just shrink or delete the log file?

Thanks for reading and waiting for any reply.

–Shrink the truncated log file to 1 MB.
–DBCC SHRINKFILE (, )
–DBCC SHRINKFILE (‘DATABASE_log’,1)

thanks in advance for your answer,

Regars, Cris

After reading many topics from Pinal I have given below the suggestions:

1. Take the log backup first (whether you want or don’t want). Then only SQL Server engine knows it and issues checkpoints to close the already opened transactions. (You may need to take a full backup first if your DB is recently restored and not taken the FULL backup till now)

2. USE ;
GO
– Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE
SET RECOVERY SIMPLE;
GO
– Shrink the truncated log file to 5120 MB.
DBCC SHRINKFILE (Log_name, 5120);
–You cannot expect the same size it may be varying depending upon the nature of the logs stored.
GO
– Reset the database recovery model.
ALTER DATABASE
SET RECOVERY FULL;
GO
3. Take a FULL backup
4. Take transaction log backups in a regular interval to avoid the unconditional growth (This is very best way of practicing to reduce the log growth).

Thanks & regards,
Vijay

If you dont care if there is log file or not then please change your Recovery model from FULL to SIMPLE.

If your DB’s Recovery model is SIMPLE you don’t need to use the code mentioned by PINAL.

I’ve SQL Express 2008 database. I have limited hard disk space on machine. I don’t care if there is log file or not. I don’t need to recover from the log file also. So I don’t want the the log file to grow bigger. Is it the best solution to execute just one command “DBCC SHRINKFILE(, 10)” periodically? or do I still need to use below three steps that you suggested originally

USE DatabaseName
GO
DBCC SHRINKFILE(, 1)
BACKUP LOG WITH TRUNCATE_ONLY
DBCC SHRINKFILE(, 1)
GO

my log file became 40Gb i want to shrink it to 5 Gb. I don’t want to backup of log file.
Can i execute follwing query:-
DBCC SHRINKFILE(log_name, 5000)

plz help me

Your suggestion was years ago but it worked. Thanks. :)

—
GO
Use dbLog
if exists
(select name from master.sys.databases where recovery_model = 1 and name = ‘dbLog’)
begin
if exists
(Select * from
(
select dateadd(n , 90, max(backup_finish_date)) as maxLogdate
from msdb..backupset bckset
where database_name = ‘dbLog’ and type = ‘L’) mm
where maxLogDate > getdate())
begin
BACKUP LOG dbLog WITH TRUNCATE_ONLY
dbcc Shrinkfile (‘dbLog_Log’, 50, truncateonly)
end
end
else
begin
BACKUP LOG dbLog WITH TRUNCATE_ONLY
dbcc Shrinkfile (‘dbLog_Log’, 50, truncateonly)
end
–

ALTER database eConfigDev SET RECOVERY SIMPLE
GO

Then confirm that it’s set to Simple (no logs used for recovery)

Select name, recovery_model_desc from sys.databases
GO

THEN, right-click on database, Tasks, SHRINK, Files, select log file, set it to maybe 1MB or even 0mb

Here’s the article that worked (took me quite a few before I found one that actually told me how to do it)

Here’s what works.

ALTER database eConfigDev SET RECOVERY SIMPLE
GO

Then confirm that it’s set to Simple (no logs used for recovery)

Select name, recovery_model_desc from sys.databases
GO

THEN, right-click on database, Tasks, SHRINK, Files, select log file, set it to maybe 1MB or even 0mb

– First, use the below code to get the file associated with the database in question.

USE [database_name]
GO

SELECT FILE_ID, name, size from sys.database_files;
GO

– Second, use the code below to truncate the log file

dbcc shrinkfile(3,truncateonly);
GO

NOTE :
Only perform this step if and only if you don’t need to restore from the log file you need to truncate.
Make sure you perform full Backup immediately after truncation is perform JUST IN CASE!

I just used this script. Working fine
