参考视频:[bbk4992]袁宝华 第十二章 - 数据移植
实验步骤:
1、test user---create table --- emp1
2、test user---create index --- emp1
3、create direcotry --- test_dir --- grant
4、show directory
5、expdp --- emp1
expdp test/test DUMPFILE=emp1.dmp DIRECTORY=test_dir tables=emp1 logfile=emp1.log
6、man-made destroy accidents
drop table emp1 purge;
7、impdp
impdp test/test DUMPFILE=emp1.dmp DIRECTORY=test_dir logfile=emp1.log
将test用户中的表emp，移植到用户user1中
