-------------------------创建表空间与用户

创建临时表空间

CREATE TEMPORARY TABLESPACE test_temp
TEMPFILE '/u01/oracle/product/10.2.0/oradata/orcl/test_temp01.dbf '
SIZE 32M
AUTOEXTEND ON
NEXT 32M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL;

创建用户表空间

CREATE TABLESPACE test_data
LOGGING
DATAFILE '/u01/oracle/product/10.2.0/oradata/orcl/my_data01.dbf '
SIZE 32M
AUTOEXTEND ON
NEXT 32M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL;

创建用户并制定表空间

CREATE USER username IDENTIFIED BY password
DEFAULT TABLESPACE TEST_DATA
TEMPORARY TABLESPACE TEST_TEMP;

SELECT * FROM USER_SYS_PRIVS;

查看用户对象或角色权限

SELECT * FROM DBA_TAB_PRIVS;
SELECT * FROM ALL_TAB_PRIVS;
SELECT * FROM USER_TAB_PRIVS;

查看所有角色
