在sqlserver2005/2008中备份数据库，收缩日志文件

---1.先备份数据库(含日志文件）
use myhis
go
backup database myhis to disk='d:\myhis_rzbak'
go


---2.设为简单恢复模式
use [master] 
go
alter database myhis set recovery simple with no_wait 
go
alter database myhis set recovery simple 
go


---3.收缩数据库日志文件为8M
use myhis
go
dbcc shrinkfile(myhis_log,8)
go

---4.重新设为完整恢复模式
use master
go
alter database myhis set recovery full with no_wait 
go
alter database myhis set recovery full
go

alter proc proc_database    @database nvarchar(50)as  begin  ---1.先备份数据库(含日志文件） execute('use '+@database+'  backup database '+@database+'  to disk=''d:\'+@database+'_rzbak''') ---2.设为简单恢复模式 execute(' use [master]   alter database '+@database+'  set recovery simple with no_wait   alter database '+@database+'  set recovery simple')  ---3.收缩数据库日志文件为8M execute(' use '+@database+'dbcc shrinkfile('+@database+'_log,8)')---4.重新设为完整恢复模式execute('  use masteralter database '+@database+'  set recovery full with no_waitalter database '+@database+'  set recovery full') ---使用示例--execute proc_database 'AmazonErp'  end
