错误---＃1396 - “RegForm_user”@'％'的操作CREATE USER失败

Question

我在创建运行此sql脚本的用户时遇到问题

CREATE DATABASE RegistrationForm
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;


CREATE USER RegForm_user;

GRANT ALL ON RegistrationForm.* TO 'RegForm_user'@'localhost' IDENTIFIED BY '@regformpswd';

USE RegistrationForm

# *************** create tables *****************

我收到此错误

    Errore
Query SQL:


CREATE USER RegForm_user
Messaggio di MySQL: Documentazione

#1396 - Operation CREATE USER failed for 'RegForm_user'@'%'

为什么会出现这个错误？
