第一次接触到12C CDB和PDB数据库，且客户提供的是ORACLE一体机，只有访问权，费劲周折，今记录12C创建默认路径表空间语句和用户
--创建默认表空间：
create tablespace tablesapce_name datafile size 500M autoextend on next 100M;
--创建用户空间：
create user username identified by password
default tablespace tablesapce_name ;
--用户授权：
grant connect,resource to username ;
grant create any sequence to username ;
grant create any table to username ;
grant delete any table to username ;
grant insert any table to username ;
grant select any table to username ;
grant unlimited tablespace to username ;
grant execute any procedure to username ;
grant update any table to username ;
grant create any view to username ;
如上~
