MySQL unknown column 'password_last_changed

问题:

When creating a user using this command:

create user 'foo'@localhost';

this error is shown:

ERROR 1054 (42S22): Unknown column 'password_last_changed' in 'mysql.user'

Using MySQL server version: 5.7.6

I tried to add it but I don't know its data-type How can I fix this?

回答1:

Apparently you upgraded your MySQL to 5.7 from an earlier version.

Column 'password_last_changed' used to exist in MySQL <5.7, but was removed since 5.7

If this is the case, you have to run 'mysql_upgrade' script to migrate some tables from the old version to the new one.

run

mysql_upgrade -u root -p

and enter your root password.

then you should have your problem solved
