SQL Server 数据库管理常用笔记

备份：

USE master
GO

BACKUP DATABASE PRE_Article TO disk @备份磁盘全路径

收缩：

USE master
GO

DUMP TRANSACTION @数据库名称 WITH NO_LOG
BACKUP LOG @数据库名称WITH NO_LOG
DBCC SHRINKDATABASE(@数据库名称)

附加：

USE master
GO

EXEC sp_attach_db
@dbname='附加数据库名称',
@filename1='数据库数据文件全路径',
@filename2='数据库日志文件全路径'

分离：

USE master
GO

EXEC sp_detach_db @dbname = N'数据库名称', @keepfulltextindexfile=N'true'

备份数据库：

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

收缩数据库：

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)

附加数据库：

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'

BAT批量生成附加数据库语句：（数据库文件同目录下运行）

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

分离数据库：

EXEC master.dbo.sp_detach_db @dbname = N'数据库名称'

BAT批量生成分离数据库语句：（数据库文件同目录下运行）

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