mssqlserver2008 收缩日志文件

将日志文件收缩到指定的目标大小

以下示例将 AdventureWorks2008R2 数据库中的日志文件收缩到 1 MB。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。

Transact-SQL

USE AdventureWorks2008R2;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE AdventureWorks2008R2
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (AdventureWorks2008R2_Log, 1);
GO
-- Reset the database recovery model.
ALTER DATABASE AdventureWorks2008R2
SET RECOVERY FULL;
GO
