cmd下操作oracle数据导库

1.cmd窗口下,登陆管理员用户:sqlplus sys/1 as sysdba 

2.创建新用户并为用户授权:

  (1)创建用户

---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
