推荐答案好吧,很明显,你没有完成这项任务,b/c甚至没有给我们足够的信息以帮助您.对于初学者来说,这是一种什么样的数据库?如果是Access,则可以通过复制MDB文件来进行备份.否则,如果您通过SQL进行备份,则只需编写SQL并执行它即可.正如其他人所说,您尝试过什么吗?您是否知道有关如何备份数据库的任何信息? Well, it''s clear you are not up to this task, b/c you don''t even give us enough info to be a ble to help you. For starters, what sort of DB is it ? If it''s Access, you can make a backup by making a copy of the MDB file. Otherwise, if you make a backup through SQL, you just write the SQL and execute it. As others said, have you tried anything ? Do you know anything about how to backup a DB ?
