Question

通过一个错误的脚本，我在Oracle 9i系统上创建了一个用户名围绕用户名（即他的用户名是'用户名'，而不是用户名）的用户。现在我想删除该用户。既不是“DROP USER'用户名'”也不是“DROP USER \'username \'”，也不是“DROP USER（SELECT username from all_users where user_id = 123）”。我该如何摆脱那个用户？

Answer 1

create user "'bla'" identified by bla;

drop user "'bla'";

Answer 2

根据Oracle's Documentation ...

“引用的标识符开始和结束用双引号（“）。如果使用a命名模式对象引用标识符，然后你必须使用每当双引号你指的是那个对象。“

所以这......

DROP USER "username" CASCADE;

Answer 3

我知道这是一篇旧帖子，但是对于因此问题搜索而遇到困扰的任何人 - 问题似乎是数据库触发器在drop用户上触发。我发布了我为Oracle XE找到的解决方案（对于其他10g版本可能也是如此） here

希望有人觉得这很有用，

Answer 4

尝试DROP USER "'username'"或DROP USER ''username''。（注意那些最后的引号都是单引号）

Answer 5

我不知道甲骨文，但你可以尝试用双引号括起来吗？

（如果错误，我会删除这个答案）

Answer 6

以下代码可能会对您有所帮助：

declare 

   sel_username varchar2(30); 
   r_user_id    varchar2(30); 
   r_username   varchar2(30); 
   user_cmd     varchar2(200); 

BEGIN
/* 
   This procedure will delete a single user_id and can be used to delete a user 
   with none displayable characters in the name 

   **Replace** the user_id  in this script to that you want to delete !!

*/      
-- select the username for a special user_id. Ther username may contain none displayed characters

   select username into sel_username from dba_users where user_id = 34; 
   select user_id, username into r_user_id , r_username from dba_users where username = sel_username ; 
   DBMS_OUTPUT.PUT_LINE('Selected user: ' || r_user_id || ' ' || r_username); 

-- If a test is needed, an alter passwort command may be usefull 
-- user_cmd := 'ALTER USER "' || r_username || '" IDENTIFIED BY PASSWORDX '; 

-- Drop the selected user 

   user_cmd := 'DROP USER "' || r_username || '" CASCADE '; 
   DBMS_OUTPUT.PUT_LINE('Executing user_cmd: ' || user_cmd ); 
   execute immediate user_cmd ; 

END;

再次提供更好的格式：

declare 

   sel_username varchar2(30); 

   r_user_id    varchar2(30); 

   r_username   varchar2(30); 

   user_cmd     varchar2(200); 

BEGIN

/* 

   This procedure will delete a single userid and can be used to delete a user 
   with none displayable characters in the name 

   **Replace the user_id  in this script !!** 

   Author: Ulrich Henkenjohann  -  March 2010 / tested on ORACLE 10.2.0.4 

*/      
-- select the username for a special user_id. Ther username may contain none displayed characters

   select username into sel_username from dba_users where user_id = 34; 

   select user_id, username into r_user_id , r_username from dba_users where username = sel_username ; 

   DBMS_OUTPUT.PUT_LINE('Selected user: ' || r_user_id || ' ' || r_username); 

-- If a test is needed, an alter passwort command may be usefull 

-- user_cmd := 'ALTER USER "' || r_username || '" IDENTIFIED BY PASSWORDX '; 

-- Drop the selected user 

   user_cmd := 'DROP USER "' || r_username || '" CASCADE '; 

   DBMS_OUTPUT.PUT_LINE('Executing user_cmd: ' || user_cmd ); 

   execute immediate user_cmd ; 

END;
