MariaDB Create User Failed

Failure in the creation of user in MariaDB can only be possible in two ways:

• By naming the user as root, whenever you will try to do it, it will result in ERROR1396.
• By naming the user as the name which is already present in the user list.

Naming the user as root – In this, you need to rename the user other than root. As whenever you will name your user as root, it will give an error.

Naming the user who is already present in the user list – To resolve this issue, you can three things which are as follows:

• By renaming the user, as the user is already present inside the user list.
• By using OR REPLACE clause to replace the already existing user.
• By using IF NOT EXISTS clause, it will only create the user if and only if the name of the user is not present inside the list.

OR REPLACE Clause

It replaces the already present name of the user.

For example,

CREATE USER 'Justin'@localhost IDENTIFIED BY 'justin123';

CREATE OR REPLACE USER 'Justin'@localhost IDENTIFIED BY 'justin123';

IF NOT EXISTS

It will only create the user only if it is not present in the user list. Instead of giving an error, it gives a warning.

For example,

CREATE USER 'Justin'@localhost IDENTIFIED BY 'justin123';

CREATE USER IF NOT EXISTS 'Justin'@localhost IDENTIFIED BY 'justin123';
