ORA-01940: cannot drop a user that is currently connected
原因是有程序在连接我们需要删除的用户,我们删除用户之前一定要先把连接断掉;
解决办法如下:
1、查找帐号下哪些连接在运行:
SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='USERNAME';
(注意:此处用户名需要大写)
SQL> SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='SSTEST';
SID SERIAL#
---------- ----------
137 41813
335 25993
464 58747
500 9153
531 50402
629 9264
631 11237
664 36180
8 rows selected.
2、删除用户进程;
SQL>ALTER SYSTEM KILL SESSION '137,41813';
System altered.
SQL>ALTER SYSTEM KILL SESSION '33525993;
System altered.
3、重新查看用户连接,并确认无连接在使用
SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='SSCRM';
4、删除用户
drop user sstest cascade ;
