不是这个问题，尝试删除用户表空间
12:24:57 [email protected](BAPRCDB)> select default_tablespace from dba_users where username=‘GSDPAY‘;

DEFAULT_TABLESPACE

GSDPAY_DATA

12:25:05 [email protected]BD1(BAPRCDB)> drop tablespace GSDPAY_DATA including contents and datafiles;

Tablespace dropped.

12:29:08 [email protected](BAPRCDB)> drop user GSDPAY cascade;
