创建临时表空间
CREATE TEMPORARY TABLESPACE test_temp TEMPFILE ' D:\data_temp.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 ' D:\data_data.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 pwd123 DEFAULT TABLESPACE TEST_DATATEMPORARY TABLESPACE TEST_TEMP;给用户授予权限
GRANT CREATE SESSION, CREATE ANY TABLE , CREATE ANY VIEW , CREATE ANY INDEX , CREATE ANY PROCEDURE , ALTER ANY TABLE , ALTER ANY PROCEDURE , DROP ANY TABLE , DROP ANY VIEW , DROP ANY INDEX , DROP ANY PROCEDURE , SELECT ANY TABLE , INSERT ANY TABLE , UPDATE ANY TABLE , DELETE ANY TABLE TO username;将role这个角色授与username,也就是说，使username这个用户可以管理和使用role所拥有的资源
