直接拷贝数据文件把数据库的数据文件(*.mdf)和日志文件(*.ldf)都拷贝到目的服务器,在SQL Server Query Analyzer中用语句进行恢复: EXEC sp_attach_db @dbname = 'test', @filename1 = 'd:mssql7data est_data.mdf', @filename2 = 'd:mssql7data est_log.ldf' 这样就把test数据库附加到SQL Server中,可以照常使用。如果不想用原来的日志文件,可以用如下的命令: EXEC sp_detach_db @dbname = 'test' EXEC sp_attach_single_file_db @dbname = 'test', @physname = 'd:mssql7data est_data.mdf' 这个语句的作用是仅仅加载数据文件,日志文件可以由SQL Server数据库自动添加,但是原来的日志文件中记录的数据就丢失了。
