Oracle常用命令-用户、表空间、赋权限、导入导出

1.1   删除表空间

drop tablespace QBKJ including contents and datafiles;

1.2   删除用户

drop user admin cascade;

1.3   创建表空间

create tablespace QBKJ  

datafile 'D:apporacle_tablespacesQBKJ.dbf'  

size 1024M  

autoextend on next 5M maxsize 20480M;

 注意：创建表空间时，路径要有，如oracle_tablespaces这个文件夹要先创建好

1.4   创建用户

create user admin identified by "qb123456" default tablespace QBKJ;

1.5   给用户赋权限

grant connect,resource to admin; 

grant dba to admin;

grant create any sequence to admin; 

grant create any table to admin; 

grant delete any table to admin; 

grant insert any table to admin; 

grant select any table to admin; 

grant unlimited tablespace to admin; 

grant execute any procedure to admin; 

grant update any table to admin; 

grant create any view to admin;

1.6   导入/导出数据（此种命令导入方式实在cmd的dos窗口下）

1.部分表导致：

imp qbkjpro/qb123456@localhost/orcl file="D:dmp_150qbkjhlw.DMP"  tables=(vacc_dic_tmp,vac_child_info) ignore=y

2.全表导入

imp admin/qb123456@localhost/orcl file="E:奇兵科技qbkj.dmp"  ignore=y full=y

 

ignore=y：表示已存在表忽略

1.全表导出：

exp admin/qb123456@localhost/orcl file="C:UsersAdministratorDesktopadmin0218.dmp"

2.部分表导出：

exp admin/qb123456@localhost/orcl file="C:UsersAdministratorDesktopadmin0218.dmp"  tables=(vacc_dic_tmp,vac_child_info)
