mysql:第41行出现错误1044 (42000)：拒绝用户访问

Question

我在mysql中遇到了一个奇怪的权限错误。

当我尝试上传备份时，我得到：

mysql DB -uDB -pPASS < files.30.12.12.sql
ERROR 1044 (42000) at line 41: Access denied for user 'DB'@'localhost' to database 'DB'

奇怪的是，我可以使用相同的用户名和密码登录到mysql consul：

mysql DB -uDB -pPASS

检查您是否也可以在手动登录时运行该SQL文件。我猜您的SQL语句不能由指定的用户(-uDB)执行。该错误并不一定意味着您未登录到MySQL，它很可能意味着您没有运行该脚本的权限

您可以通过执行如下所示的简单语句来尝试登录

mysql DB -uDB -pPASS < SHOW TABLES
