Sql Server 2005 日志文件清除，收缩

一、

1.DUMP TRANSACTION 数据库名称 WITH NO_LOG   

2.在数据库上点右键->任务->收宿->文件，文件类型改为：日志，将文件收宿到1M。（如果未达到收容目标，多执行几次）

二、

清除日志：--以下代码未经验证 DECLARE @LogicalFileName sysname,        @MaxMinutes INT,        @NewSize INTUSE     szwzcheck             -- 要操作的数据库名SELECT  @LogicalFileName = 'szwzcheck_Log',  -- 日志文件名@MaxMinutes = 10,               -- Limit on time allowed to wrap log.        @NewSize = 20                  -- 你想设定的日志文件的大小(M)-- Setup / initializeDECLARE @OriginalSize intSELECT @OriginalSize = size   FROM sysfiles  WHERE name = @LogicalFileNameSELECT 'Original Size of ' + db_name() + ' LOG is ' +         CONVERT(VARCHAR(30),@OriginalSize) + ' 8K pages or ' +         CONVERT(VARCHAR(30),(@OriginalSize*8/1024)) + 'MB'  FROM sysfiles  WHERE name = @LogicalFileNameCREATE TABLE DummyTrans  (DummyColumn char (8000) not null)DECLARE @Counter   INT,        @StartTime DATETIME,        @TruncLog  VARCHAR(255)SELECT  @StartTime = GETDATE(),        @TruncLog = 'BACKUP LOG ' + db_name() + ' WITH TRUNCATE_ONLY'DBCC SHRINKFILE (@LogicalFileName, @NewSize)EXEC (@TruncLog)-- Wrap the log if necessary.WHILE     @MaxMinutes > DATEDIFF (mi, @StartTime, GETDATE()) -- time       AND @OriginalSize = (SELECT size FROM sysfiles WHERE name = @LogicalFileName)
