SQL Server 数据库清空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

　　使用时将db_develop更换为你需要操作的数据库名即可。
