收缩sqlserver事务日志

若要允许 DBCC SHRINKFILE 命令收缩文件，首先需要通过将数据库恢复模式设置为 SIMPLE 来截断该文件。

示例，收缩数据库abce的事务日志

USE abce;

GO

-- Truncate the log by changing the database recovery model to SIMPLE.

ALTER DATABASE abce

SET RECOVERY SIMPLE;

GO

-- Shrink the truncated log file to 1 MB.

DBCC SHRINKFILE (abce_Log, 1);

GO

-- Reset the database recovery model.

ALTER DATABASE abce

SET RECOVERY FULL;

GO
