MySql的错误解决:错误码1396

Whenever you had try to run query which create a User as Shown Below. MySql> CREATE USER 'springstudent'@'localhost' IDENTIFIED BY 'springstudent'; GRANT ALL PRIVILEGES ON * . * TO 'springstudent'@'localhost'; But when you try to run query which create user within all previleges, Due to bug it create gives previleges without showing user Because of this Problem we need to use this script for flush priviledges MySql> drop user 'springstudent'@'localhost'; flush privileges; create user admin@localhost identified by 'admins_password' After deleting the user, there is need to flush the mysql privileges Then Create User again

Gotchaaa ....Solved ....

是的，这个bug就在那里。然而，我找到了一个小小的变通办法。

假设用户在那里，那么删除用户 删除用户后，需要刷新mysql权限 现在创建用户。

这应该能解决问题。假设我们要创建admin @ localhost用户，下面的命令如下:

drop user admin@localhost;
flush privileges;
create user admin@localhost identified by 'admins_password'

我和OP有同样的问题，接受的答案不适合我。在接受答案的评论中，@Rathish发布了一个对我有用的解决方案，我想引起大家的注意。

这是链接:

https://www.rathishkumar.in/2018/10/Error-1396-HY000-Operation-CREATE-DROP-USER-failed-for-user-host.html

Rathish的解决方案是撤销所有用户的访问权限:

REVOKE ALL ON *.* FROM 'user'@'host';
DROP USER 'user'@'host';
FLUSH PRIVILEGES;

他还很有帮助地指出，你可以通过选择“user”和“host”来查询下面的表格，以确定你是否有之前操作留下的残留用户:

mysql.user: User accounts, global privileges, and other non-privilege columns
mysql.db: Database-level privileges
mysql.tables_priv: Table-level privileges
mysql.columns_priv: Column-level privileges
mysql.procs_priv: Stored procedure and function privileges
mysql.proxies_priv: Proxy-user privilege

谢谢你！

我今天遇到了这个问题，我通过以下步骤解决了它:

1)手动在mysql.user中插入麻烦的用户提供的必填字段值

mysql> insert into user(Host, User, Password, ssl_type) 
   values ('localhost', 'jack', 'jack', 'ANY');

2)

mysql> select * from user where User = 'jack';
   1 row in set (0.00 sec)

3)。

mysql> drop user jack;
Query OK, 0 rows affected (0.00 sec)

B. mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

C. mysql> create user 'jack' identified by 'jack';
Query OK, 0 rows affected (0.00 sec)

D. mysql> select Host, User, Password, ssl_type  from user where User = 'jack';
+-----------+-----------+-------------------------------------------+----------+
| Host      | User      | Password                                  | ssl_type |
+-----------+-----------+-------------------------------------------+----------+
| localhost | jack      | jack                                      | ANY      |
| %         | jack      | *45BB7035F11303D8F09B2877A00D2510DCE4D758 |          |
+-----------+-----------+-------------------------------------------+----------+
2 rows in set (0.00 sec)

4)。

mysql> delete from user 
 where User = 'nyse_user' and 
       Host = 'localhost' and 
       Password ='nyse';
Query OK, 1 row affected (0.00 sec)

B.

mysql> select Host, User, Password, ssl_type  from user where User = 'jack';
+------+-----------+-------------------------------------------+----------+
| Host | User      | Password                                  | ssl_type |
+------+-----------+-------------------------------------------+----------+
| %    | jack      | *45BB7035F11303D8F09B2877A00D2510DCE4D758 |          |
+------+-----------+-------------------------------------------+----------+
1 row in set (0.00 sec)

希望这能有所帮助。

删除用户，刷新权限;然后，创建用户。它确实有效!

如果要删除一个使用sql语句的用户，需要先删除columns_priv、db、procs_priv、tables_priv表中的相关数据。然后执行flush特权;
