SQL Server 備份、還原、附加、分離數據庫 批量語句

以下例子是我在實際生產環境中使用過的，在查詢分析器中運行。

備份數據庫：

use master
declare @ls_time varchar(100)
declare @ls_dbname varchar(100)
set @ls_time = convert(varchar, getdate(), 112) + '_' + replace(convert(varchar, getdate(), 108), ':', '')

set @ls_dbname = 'D:\data\backup\' + @ls_time + '_PRE_Article.bak'
BACKUP DATABASE PRE_Article TO disk = @ls_dbname

set @ls_dbname = 'D:\data\backup\' + @ls_time + '_PRE_Supply.bak'
BACKUP DATABASE PRE_Supply TO disk = @ls_dbname

set @ls_dbname = 'D:\data\backup\' + @ls_time + '_PRE_Ask.bak'
BACKUP DATABASE PRE_Ask TO disk = @ls_dbname

-- ...... 按上面格式添加

收縮數據庫：

DUMP TRANSACTION PRE_Article WITH NO_LOG
BACKUP LOG PRE_Article WITH NO_LOG
DBCC SHRINKDATABASE(PRE_Article)

DUMP TRANSACTION PRE_Supply WITH NO_LOG
BACKUP LOG PRE_Supply WITH NO_LOG
DBCC SHRINKDATABASE(PRE_Supply)

DUMP TRANSACTION PRE_Ask WITH NO_LOG
BACKUP LOG PRE_Ask WITH NO_LOG
DBCC SHRINKDATABASE(PRE_Ask)

-- ...... 按上面格式添加

附加數據庫：

EXEC sp_attach_db @dbname = 'PRE_Article'
,@filename1 = 'E:\Data\PRE_Article_Data.MDF' 
,@filename2 = 'E:\Data\PRE_Article_Log.LDF'   

EXEC sp_attach_db @dbname = 'PRE_Supply'
,@filename1 = 'E:\Data\PRE_Supply_Data.MDF' 
,@filename2 = 'E:\Data\PRE_Supply_Log.LDF'

EXEC sp_attach_db @dbname = 'PRE_Ask'
,@filename1 = 'E:\Data\PRE_Ask_Data.MDF' 
,@filename2 = 'E:\Data\PRE_Ask_Log.LDF'

-- ...... 按上面格式添加

BAT批量生成附加數據庫語句：（數據庫文件同目錄下運行）

 ECHO USE [master] >> 附加.sql
ECHO GO >> 附加.sql
FOR %%I IN (*.mdf) DO ECHO CREATE DATABASE [%%~nI] ON >> 附加.sql
FOR %%I IN (*.mdf) DO ECHO (FILENAME = N'%%~dpnxI'), >> 附加.sql
FOR %%I IN (*.ldf) DO ECHO (FILENAME = N'%%~dpnxI') >> 附加.sql
ECHO FOR ATTACH >> 附加.sql
ECHO GO >> 附加.sql
::sqlcmd -i 附加.sql
::del 附加.sql
ECHO.
::PAUSE

BAT批量生成分離數據庫語句：（數據庫文件同目錄下運行）

 FOR %%I IN (*.mdf) DO echo EXEC master.dbo.sp_detach_db @dbname = N'%%~nI', @keepfulltextindexfile=N'true' >> 分離.sql
ECHO.
::PAUSE
