   sql 在使用中每次查询都会生成日志,但是如果你长久不去清理,可能整个硬都堆满哦,笔者就遇到这样的情况,直接网站后台都进不去了。下面我们一起来学习一下如何清理这个日志吧

  SQL2005清空删除日志:

  复制代码 代码如下:

  Backup Log DNName with no_log '这里的DNName是你要收缩的数据库名,自己注意修改下面的数据库名,我就不再注释了。

  go

  dump transaction DNName with no_log

  go

  USE DNName

  DBCC SHRINKFILE (2)

  Go

  SQL2008清空删除日志:

  '在SQL2008中清除日志就必须在简单模式下进行,等清除动作完毕再调回到完全模式。

  复制代码 代码如下:

  USE [master]

  GO

  ALTER DATABASE DNName SET RECOVERY SIMPLE WITH NO_WAIT

  GO

  ALTER DATABASE DNName SET RECOVERY SIMPLE --简单模式

  GO

  USE DNName

  GO

  DBCC SHRINKFILE (N'DNName_Log' , 11, TRUNCATEONLY)

  GO

  '这里的DNName_Log 如果不知道在sys.database_files里是什么名字的话,可以用以下注释的语句进行查询

  'USE DNName

  'GO

  'SELECT file_id, nameFROM sys.database_files;

  'GO

  USE [master]

  GO

  ALTER DATABASE DNName SET RECOVERY FULL WITH NO_WAIT

  GO

  ALTER DATABASE DNName SET RECOVERY FULL --还原为完全模式

  GO

  sqlserver2000压缩日志
