I used to run a one-liner for creating a new database and adding a new user to it, with a custom password. It looked like this:
mysql> GRANT ALL PRIVILEGES ON ohdear_ci.* TO 'ohdear_ci'@'localhost' IDENTIFIED BY 'ohdear_secret';
In MySQL 8 however, you'll receive this error message.
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'ohdear_secret'' at line 1
The reason appears to be that MySQL dropped support for this short-hand version and now requires the slightly longer version instead.
mysql> CREATE USER 'ohdear_ci'@'localhost' IDENTIFIED BY 'ohdear_secret'; Query OK, 0 rows affected (0.11 sec) mysql> GRANT ALL ON ohdear_ci.* TO 'ohdear_ci'@'localhost'; Query OK, 0 rows affected (0.15 sec)
If you have scripting in place that uses the short, one-liner version, be aware those might need changing if you move to MySQL 8.
