sp2-0734:未知的命令开头'imp 忽略了剩余行默认分类

应该是在cmd的dos命令提示符下执行,而不是在sqlplus里面。。。。。。但是格式一定要类似于:

imp PERSONNEL_MANAGE/MWQ@DBSQL full=y  file=C:personnel_manage.dmpignore=y

谨以此纪念我的粗心。。。。。我错了。

 

imp 命令是在dos提示符下执行的。
直接cmd后执行而不是在sql下执行的


数据导出:
1 将数据库TEST完全导出,用户名system 密码manager 导出到D:daochu.dmp中
   exp system/manager@TEST file=d:daochu.dmp full=y
2 将数据库中system用户与sys用户的表导出
   exp system/manager@TEST file=d:daochu.dmp owner=(system,sys)
3 将数据库中的表inner_notify、notify_staff_relat导出
    exp aichannel/aichannel@TESTDB2 file= d:datanewsmgnt.dmp tables=(inner_notify,notify_staff_relat)

4 将数据库中的表table1中的字段filed1以"00"打头的数据导出
   exp system/manager@TEST file=d:daochu.dmp tables=(table1) query=" where filed1 like '00%'"

  上面是常用的导出,对于压缩,既用winzip把dmp文件可以很好的压缩。
  也可以在上面命令后面 加上 compress=y 来实现。

数据的导入
1 将D:daochu.dmp 中的数据导入 TEST数据库中。
   imp system/manager@TEST  file=d:daochu.dmp
   imp aichannel/aichannel@HUST full=y  file=d:datanewsmgnt.dmp ignore=y
   上面可能有点问题,因为有的表已经存在,然后它就报错,对该表就不进行导入。
   在后面加上 ignore=y 就可以了。
2 将d:daochu.dmp中的表table1 导入
imp system/manager@TEST  file=d:daochu.dmp  tables=(table1)

 

基本上上面的导入导出够用了。不少情况要先是将表彻底删除,然后导入。

注意:
操作者要有足够的权限,权限不够它会提示。
数据库时可以连上的。可以用tnsping TEST 来获得数据库TEST能否连上。


当然,上面的方法在导出数据时可能会导出很大的包,那是因为你的用户可能在授权的时候授予了DBA的权限,所以可以采用下面方法来进行数据库备份:

数据库备份
建议系统过渡后,每周进行一次备份。或者在数据表发生重大改变前,对要改变的数据表进行备份。
执行以下步骤,进行备份。
在命令行里,敲入“cmd”,回车,进入命令行窗口。
在窗口中,输入:
exp mas/123456@mas

系统提示:输入数组提取缓冲区大小: 4096 >
可以直接回车;

系统提示:导出文件: EXPDAT.DMP>
此处输入导出文件的位置,其路径必须存在,Oracle在这里不会自动建立路径,但可以建立文件名。备份文件以dmp作为后缀。
输入内容如:e:workmas_db_090925v1.dmp 回车

系统提示: (1)E(完整的数据库),(2)U(用户) 或 (3)T(表): (2)U > u
此处可以输入u,也可以直接回车,因为系统此时默认的是U

系统提示:导出权限(yes/no):yes>回车

系统提示:导出表数据(yes/no):yes>回车

系统提示:压缩区(yes/no):yes>回车

系统提示:要导出的用户: (RETURN 以退出) > mas

系统提示:要导出的用户: (RETURN 以退出) > 回车

此时系统会自动进行备份
