在SQL SERVER 2008 中 BACKUP LOG WITH TRUNCATE_ONLY 已不再被支持,要收缩数据库日志,首先需要通过将数据库恢复模式设置为 SIMPLE 来截断该文件。语句如下:
Code USE DATABASENAME; GO -- Truncate the log by changing the database recovery model to SIMPLE. ALTERDATABASE DATABASENAME SET RECOVERY SIMPLE; GO -- Shrink the truncated log file to 1 MB. DBCC SHRINKFILE (DATABASENAME_Log, 1); GO -- Reset the database recovery model. ALTERDATABASE DATABASENAME SET RECOVERY FULL; GO
要收缩已做镜像的数据库的日志文档,用
USE DATABASENAME; GO
BACKUPLOG DATABASENAME TODISK='文件路径.'
-- Shrink the truncated log file to 1 MB. DBCC SHRINKFILE (DATABASENAME_Log, 1); GO
