SQL server清空数据库日志脚本

/*设置为简单模式*/
USE [master]
ALTER DATABASE {0} SET RECOVERY SIMPLE WITH NO_WAIT
ALTER DATABASE {0} SET RECOVERY SIMPLE 

/*获取日志文件名称*/
USE {0}
Declare @logname nvarchar(200)
SELECT @logname=name FROM sys.database_files where type=1 

/*收缩日志文件*/
DBCC SHRINKFILE (@logname , 0, TRUNCATEONLY)  

/*还原为完全模式*/
USE [master]
ALTER DATABASE {0} SET RECOVERY FULL WITH NO_WAIT
ALTER DATABASE {0} SET RECOVERY FULL

{0}替换成数据库名称即可。
