如何减少SQL Server 2014数据库的大小

Question

I have a SQL Server 2014 database dump which is approx. 60GB large. In SQL Server Management Studio, it is shown for the original DB, that the "ROWS Data" has an initial size of ~ 99000MB and the "LOG" has an initial size of ~ 25600MB.

Now there are a view tables in the Database which are about 10GB large and which I can flush/clean.

After deleting the data inside those tables, what is the best way to decrease the physical size of the database? A lot of posts I discovered are dealing with SHRINKDATABASE but some articles won't recommend it because of bad fragmentation and performance.

Thanks in advance.

Answer 1

Here is a code I have used to reduce the space used and free up Database space and actual Drive space. Hope this helps.

USE YourDataBase;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE YourDataBase
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (YourDataBase_log, 1);
GO
-- Reset the database recovery model.
ALTER DATABASE YourDataBase
SET RECOVERY FULL;
GO

Answer 2

Instead of use DBCC SHRINKDATABASE I suggest you to use DBCC SHRINKFILE , obviously your tables should be stored on different FILEGROUP. Then you can reduce the physical size of your database optimizing fragmentation.

Hope this could help

You need to shrink your DataBase by using below Query.

ALTER DATABASE [DBNAME] SET RECOVERY SIMPLE WITH NO_WAIT
DBCC SHRINKFILE(PTechJew_LOG, 1)
ALTER DATABASE [DBNAME] SET RECOVERY FULL WITH NO_WAIT

After run this query check your log file. Its Worked.
