Oralce创建表用户和导入导出dmp文件

1、查看表空间名字：

select distinct TABLESPACE_NAME from tabs

2、查看几个表空间：

select count(distinct TABLESPACE_NAME) from tabs

3、创建表空间

create tablespace tj_apartmentorasys logging datafile
'D:\ORACLE\PRODUCT\10.2.0\ORADATA\RESOURCE\tj_apartmentorasys.dbf'
size 1024m autoextend on next 50m maxsize
unlimited extent management local segment space management auto;

4、创建用户并赋权限

create user integration
default tablespace sdzjypt
identified by integration;
grant dba to integration;
grant select any table to integration;
grant insert any table to integration;
grant update any table to integration;
grant delete any table to integration;
alter user integration account unlock;

查询用户表空间

select * from dba_users;
select username,default_tablespace from dba_users;

查询现有连接用户

select * from v$session;

查看表空间信息

select file_name,tablespace_name from dba_data_files;

select name from v$datafile;

数据库导出

exp test/test@192.168.4.118/resource file=C:\1\test.dmp

导出数据表

exp system/manager@TEST file=d:\daochu.dmp tables=(table1,table2)

数据库导入

imp test/test@192.168.4.118/resource file=C:\test.dmp full=y

创建表空间

create smallfile tablespace xtz logging  datafile '+DATA/shitan/datafile/xtz.dbf' size 1024m autoextend on next 50m maxsize unlimited extent management local segment space management auto;

创建用户
