SQLServer收缩数据库日志的方法

1、查看数据库日志大小

dbcc sqlperf(logspace)

2、收缩数据库

比如数据库名称为ZYWY，则语句如下：

USE ZYWY;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE ZYWY
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (ZYWY_log, 100);
GO
-- Reset the database recovery model.
ALTER DATABASE ZYWY
SET RECOVERY FULL;
GO
