我在mysql中创建了一个数据库并运行命令-create user 'aquaman'@'localhost' identified by password'aquaman123';ERROR 1396 (HY000): Operation CREATE USER failed for 'aquaman'@'localhost'
有谁能帮我解决这个问题
我错误地从mysql.user表中删除了根用户。delete from mysql.user where user='username';CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';ERROR 1396 (HY000): Operation CREATE
