-----創建表空間
create tablespace JTKMS datafile 'E:\app\xys\oradata\orcl\zqdb.dbf' size 50m autoextend on next 50m maxsize 512m extent management local;
-----創建表用戶
create user newkm identified by newkm default tablespace JTKMS temporary tablespace temp quota unlimited on JTKMS;
--刪除表空間,如果其他表空間中的表有外鍵等約束關聯到了本表空間中的表的字段，就要加上CASCADE CONSTRAINTS
drop tablespace tablespace_name including contents and datafiles CASCADE CONSTRAINTS;
--刪除表用戶,說明： 刪除了user，只是刪除了該user下的schema objects，是不會刪除相應的tablespace的。
drop user username cascade
