SQL Server 數據庫清空ldf日志文件

USE [master]
ALTER DATABASE [DB_Develop]
SET RECOVERY SIMPLE WITH NO_WAIT
ALTER DATABASE [DB_Develop] 
SET RECOVERY SIMPLE
GO
USE [DB_Develop]
DECLARE @logname VARCHAR(150)
SELECT @logname = NAME
FROM   sys.database_files
WHERE  NAME LIKE'%log'
DBCC SHRINKFILE(@logname, 11, TRUNCATEONLY)
GO
USE [master]
ALTER DATABASE [DB_Develop]
SET RECOVERY FULL WITH NO_WAIT
ALTER DATABASE [DB_Develop] 
SET RECOVERY FULL
GO

　　使用時將DB_Develop更換為你需要操作的數據庫名即可。
