ORA-00959: tablespace 'TB01' does not exist

当前的表空间如下：

SQL> select name from v$tablespace;
 
NAME
--------------------------------------------------------------------------------
SYSTEM
SYSAUX
UNDOTBS1
USERS
TEMP
tb01
tb02

删除表空间，报错如下

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：建立表空间的时候，使用了小写名称

解决办法：因此删除时候必须加上双引号

SQL> drop tablespace "tb01" including contents and datafiles;
 
Tablespace dropped.
