Here is another SQL script that I keep handy in my toolbox: Shrink All Database Files.sql. Unlike the script that I shared in my previous post that simply truncated all transaction logs to free up disk space, this script is suitable for running in a Production environment (PROD), as well as in non-production environments, such as a shared Development environment (DEV).
Here is the script:
DROP TABLE #CommandQueue CREATE TABLE #CommandQueue ( ID INT IDENTITY ( 1, 1 ) , SqlStatement VARCHAR(1000) ) INSERT INTO #CommandQueue ( SqlStatement ) SELECT 'USE [' + A.name + '] DBCC SHRINKFILE (N''' + B.name + ''' , 1)' FROM sys.databases A INNER JOIN sys.master_files B ON A.database_id = B.database_id WHERE A.name NOT IN ( 'master', 'model', 'msdb', 'tempdb' ) DECLARE @id INT SELECT @id = MIN(ID) FROM #CommandQueue WHILE @id IS NOT NULL BEGIN DECLARE @sqlStatement VARCHAR(1000) SELECT @sqlStatement = SqlStatement FROM #CommandQueue WHERE ID = @id PRINT 'Executing ''' + @sqlStatement + '''...' EXEC (@sqlStatement) DELETE FROM #CommandQueue WHERE ID = @id SELECT @id = MIN(ID) FROM #CommandQueue END
As you can see, this script follows the same pattern that I described in my previous post.
I have found this script to be especially useful when working with Microsoft Office SharePoint Server (MOSS) 2007, because I sometimes migrate large amounts of content when working on certain features (particularly Search) but later decide to remove the content and need to recover the disk space on my VM.
