I MySQL 5.7 blev adgangskodefeltet i mysql.user table-feltet fjernet, nu er feltnavnet 'authentication_string'.
Vælg først databasen:
mysql>use mysql;
Og vis så tabellerne:
mysql>show tables;
Du finder brugertabellen, lad os nu se dens felter:
mysql> describe user;

Overraskelse！Der er intet felt med navnet 'adgangskode', adgangskodefeltet hedder 'autentication_string'. Så gør bare dette:
update user set authentication_string=password('1111') where user='root';
Nu vil alt være ok.
Sammenlignet med MySQL 5.6 er ændringerne ret omfattende:Hvad er nyt i MySQL 5.7
