---Create the user create user Helq3_Pro identified by "1" default tablespace MOF temporary tablespace TEMP profile DEFAULT;
(2)为用户授权
SQL> grant dba to helq3_cpbgt_20200714 with admin option; SQL> grant unlimited tablespace to helq3_cpbgt_20200714 with admin option; SQL> grant imp_full_database to helq3_cpbgt_20200714;
3.数据导入
(1)imp导入:imp userid=helq3_cpbgt_20200714/1@orcl file=E:\cpcz.dmp full=y ignore=y
(2)数据泵导入impdp
首先,创建,并为用户授权此文件夹
数据泵导入:impdp helq3_cpbgt_20200714/1 dumpfile=cpcz.dmp directory=expdp_dir remap_schema=helq3_cpbgt_20200714(导出时的用户名):helq3_cpbgt_20200714
4.数据导出
(1)exp导出: exp helq3_cpbgt_20200714/1@orcl file=E:\cpcz.dmp log=cpcz.log
导出带空表的数据库->先做查询,再正常导出:select ‘alter table ‘||table_name||‘ allocate extent;‘ from user_tables where num_rows=0;
(2)expdp 数据泵导出:expdp helq3_cpbgt_20200714/1@orcl schemas=helq3_cpbgt_20200714 dumpfile=cpcz.dmp directory=expdp_dir logfile=cpcz.log
