imp help=y
导入自己的表:
exp scott/tiger@orcl tables=(student, address) file=D:scott_stu_add.dmp log=D:scott_stu_add.log
imp scott/tiger@orcl file=D:scott_stu_add.dmp log=D:log.log
imp scott/tiger@orcl file=D:scott_stu_add.dmp tables=student
导入别人的表:
conn sys as sysdba;
drop user test cascade;
create user test identified by test;
下面是对的:
imp test/test@orcl file=D:scott_stu_add.dmp fromuser=scott touser=test
imp sys/change_on_install@orcl file=D:scott_stu_add.dmp fromuser=scott touser=test
上面已经导入了,但又重复执行,会报错
imp test/test@orcl file=D:scott_stu_add.dmp fromuser=scott touser=test
加上ignore 后,create 语句错误被忽略了,接着会执行后面的语句
imp test/test@orcl file=D:scott_stu_add.dmp fromuser=scott touser=test ignore=y
下面这个是不对的:
imp scott/tiger@orcl file=D:scott_stu_add.dmp fromuser=scott touser=test
