移动Sql Server数据库的脚本

前段时间做过这么一件事情,把原本放在c盘的所有数据库(除了sql server系统文件外)文件Move到D盘,主要是为了方便后续管理以及减少磁盘I/O阻塞(C,D是2个独立磁盘)。

脚本很简单,在此只是记录下来,以免以后忘记,也方便复用:

这个脚本只有2个参数需要输入,即:目标数据库名字目标目录

 

USE master

GO



DECLARE

    @DBName sysname,

    @DestPath varchar(256)

DECLARE @DB table(

    name sysname,

    physical_name sysname)





BEGIN TRY



SELECT

    @DBName = 'TargetDatabaseName',   --input database name

    @DestPath = 'D:\SqlData\'         --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

WHERE A.type <=1



--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,

    physical_name

FROM @DB

OPEN curMove

    FETCH NEXT FROM curMove INTO @login_name,@physical_name

        WHILE @@FETCH_STATUS = 0

        BEGIN

            SET @temp_name = RIGHT(@physical_name,CHARINDEX('\',REVERSE(@physical_name)) - 1)

            EXEC('exec xp_cmdshell ''move "' + @physical_name + '" "' + @DestPath + '"''')

            EXEC('ALTER DATABASE ' + @DBName + ' MODIFY FILE ( NAME = ' + @login_name

                    + ', FILENAME = ''' + @DestPath + @temp_name + ''')')

            FETCH NEXT FROM curMove INTO @login_name,@physical_name

        END

CLOSE curMove

DEALLOCATE curMove



-- set online

EXEC('ALTER DATABASE ' + @DBName + ' SET ONLINE')



-- show result

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

END TRY

BEGIN CATCH

    SELECT ERROR_MESSAGE() AS ErrorMessage

END CATCH

GO
