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.
