批处理(bat)实现SQLServer数据库备份与还原

备份数据库.bat

@echo off
set path=%path%;C:\Program Files (x86)\Microsoft SQL Server\80\Tools\Binn
echo 数据库备份开始
osql.exe -S 127.0.0.1 -U sa -P 123456 -i sqlserverbackup.sql -o c:\backup\sqlserverbackup.out
echo 数据库备份完成
pause

sqlserverbackup.sql

DECLARE @name varchar(50)
DECLARE @datetime char(14)
DECLARE @path varchar(255)
DECLARE @bakfile varchar(255)
set @name='DataSample'
set @datetime=CONVERT(char(8),getdate(),112) + REPLACE(CONVERT(char(8),getdate(),108),':','')
set @path='c:\backup\'
set @bakfile=@path+''+@name+'_'+'bak_'+@datetime+'.BAK'
backup database @name to disk=@bakfile with name=@name
go

还原数据库.bat
