已经适用大多数情况(SQLServer2005/2008):


USE master
GO

DECLARE   
    @DBName sysname,
    @DestPath varchar(256)
DECLARE @DB table(
    name sysname,
    physical_name sysname)


BEGIN TRY

SELECT
    @DBName = 'FF',   --input database name
    @DestPath = 'E:\' --input destination path


--kill database processes
DECLARE @SPID varchar(20)
DECLARE curProcess CURSOR FOR

SELECT spid
FROM sys.sysprocesses
WHERE DB_NAME(dbid) = @DBName

OPEN curProcess
    FETCH NEXT FROM curProcess INTO @SPID
    WHILE @@FETCH_STATUS = 0
    BEGIN
            EXEC('KILL ' + @SPID)
            FETCH NEXT FROM curProcess
    END
CLOSE curProcess
DEALLOCATE curProcess

--query physical name

INSERT @DB(
    name,
    physical_name)
SELECT
    A.name,
    A.physical_name
FROM sys.master_files A
INNER JOIN sys.databases B
    ON A.database_id = B.database_id
        AND B.name = @DBName

--set offline
EXEC('ALTER DATABASE ' + @DBName + ' SET OFFLINE')

--move to dest path
DECLARE
    @login_name sysname,
    @physical_name sysname,
    @temp_name varchar(256)
DECLARE curMove CURSOR FOR
SELECT
    name,

    FETCH NEXT FROM curMove INTO @login_name,@physical_name
        WHILE @@FETCH_STATUS = 0

            EXEC('exec xp_cmdshell ''move "' + @physical_name + '" "' + @DestPath + '"''')
            EXEC('ALTER DATABASE ' + @DBName + ' MODIFY FILE ( NAME = ' + @login_name
