ORA-01940: cannot drop a user that is currently connecte

当我们删除某个用户时，如果要删除的用户当前正连接Oracle数据库，则会报错：

SQL> conn /as sysdba
Connected.

SQL> drop user fc cascade;
drop user fc cascade

ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected.

通过v$session视图查出要删除的用户当前session信息，然后kill掉该用户session连接：

SQL> select sid,serial# from v$session where username='FC';
SID SERIAL#

---------- ----------

150 9019
SQL> alter system kill session '150,9019';
System altered.

再执行drop user操作便可成功：

SQL> drop user fc cascade;
User dropped.
