DROP用户'netbeansuser'@'％';抛出错误HY000（1396）MySQL

Question

我错误地创建了一个我现在无法删除的用户。以下是与MySQL交互的代码片段：

mysql> DROP User 'netbeansuser'@'%';
ERROR 1396 (HY000): Operation DROP USER failed for 'netbeansuser'@'%'
mysql> select User from mysql.user;
+------------------+
| User             |
+------------------+
| root             |
| root             |
| debian-sys-maint |
| netbeansuser     |
| root             |
| root             |
+------------------+
6 rows in set (0.00 sec)

mysql> DROP User 'netbeansuser';
ERROR 1396 (HY000): Operation DROP USER failed for 'netbeansuser'@'%'
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> select User from mysql.user;
+------------------+
| User             |
+------------------+
| root             |
| root             |
| debian-sys-maint |
| netbeansuser     |
| root             |
| root             |
+------------------+
6 rows in set (0.00 sec) 

mysql> DROP User 'netbeansuser';
ERROR 1396 (HY000): Operation DROP USER failed for 'netbeansuser'@'%'
mysql> DROP User 'netbeansuser'@'%';
ERROR 1396 (HY000): Operation DROP USER failed for 'netbeansuser'@'%'

我做错了什么？特别是什么是＆＃39;％＆＃39;在主机名上签名？我在创建用户时没有指定主机名。了解MySQL用户创建中的主机名绑定的任何资源也会有所帮助。谢谢大家。

这会有所帮助。

使用'localhost'代替'％'。
