SQL Server 2008 R2下如何清理数据库日志文件

废话不多说，直接上代码，清理后日志文件为1M

[sql] 
USE [master]  
GO  
ALTER DATABASE [数据库名] SET RECOVERY SIMPLE WITH NO_WAIT  
GO  
ALTER DATABASE [数据库名] SET RECOVERY SIMPLE  
GO  
USE [数据库名]  
GO  
DBCC SHRINKFILE (N'[数据库日志文件名称]' , 0,TRUNCATEONLY)  
GO  
USE [master]  
GO  
ALTER DATABASE [数据库名] SET RECOVERY FULL WITH NO_WAIT  
GO  
ALTER DATABASE [数据库名] SET RECOVERY FULL  
GO

--查询指定数据库的日志文件名称

USE [数据库名]   
GO  
SELECT name FROM SYS.database_files WHERE type_desc='LOG'

08R2通过，其他版本未测试
