imp help=y
匯入自己的表:
exp scott/[email protected] tables=(student, address) file=D:\scott_stu_add.dmp log=D:\scott_stu_add.log
imp scott/[email protected] file=D:\scott_stu_add.dmp log=D:log.log
imp scott/[email protected] file=D:\scott_stu_add.dmp tables=student
匯入別人的表:
conn sys as sysdba;
drop user test cascade;
create user test identified by test;
下面是對的:
imp test/[email protected] file=D:\scott_stu_add.dmp fromuser=scott touser=test
imp sys/[email protected] file=D:\scott_stu_add.dmp fromuser=scott touser=test
上面已經匯入了,但又重複執行,會報錯
imp test/[email protected] file=D:\scott_stu_add.dmp fromuser=scott touser=test
加上ignore 後,create 語句錯誤被忽略了,接著會執行後面的insert語句
imp test/[email protected] file=D:\scott_stu_add.dmp fromuser=scott touser=test ignore=y
下面這個是不對的:
imp scott/[email protected] file=D:\scott_stu_add.dmp fromuser=scott touser=test
oracle imp dmp
