介绍关于sqlserver数据库移动数据库路径的脚本
前几天做过这么一件事，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）。脚本需输入2个参数：目标数据库名字和目标目录
复制代码 代码如下:
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
