ORA-00959: tablespace 'TB01' does not exist

當前的表空間如下：

SQL> select name from v$tablespace;

NAME
--------------------------------------------------------------------------------
SYSTEM
SYSAUX
UNDOTBS1
USERS
TEMP
tb01
tb02

刪除表空間，報錯如下

SQL> drop tablespace tb01 including contents and datafiles;
drop tablespace tb01 including contents and datafiles
*
ERROR at line 1:
ORA-00959: tablespace 'TB01' does not exist

原因：建立表空間的時候，使用了小寫名稱

解決辦法：因此刪除時候必須加上雙引號

SQL> drop tablespace "tb01" including contents and datafiles;

Tablespace dropped.
